Abstract
In this study, we engineered liposomal indocyanine green (ICG) to maximize its photothermal effects while maintaining the fluorescence intensity. Various liposomal formulations of ICG were prepared by varying the lipid composition and the molar ratio between total lipid and ICG, and their photothermal characteristics were evaluated under near-infrared irradiation. We showed that the ICG dispersity in the liposomal membrane and its physical interaction with phospholipids were the main factors determining the photothermal conversion efficiency. In phototherapeutic studies, the optimized formulation of liposomal ICG showed greater anticancer effects in a mouse tumor model compared with other liposomal formulations and the free form of ICG. Furthermore, we utilized liposomal ICG to visualize the metastatic lymph node around the primary tumor under fluorescence imaging guidance and ablate the lymph node with the enhanced photothermal effect, indicating the potential for selective treatment of metastatic lymph node.

Abstract
Both photothermal therapy (PTT) and photodynamic therapy (PDT) are phototherapeutic approaches, which have been widely investigated for cancer therapy mediated by an external light source. Here, a nanosystem presenting the synchronous PTT and PDT effect realized through one-step near-infrared (NIR) light irradiation is reported. This system was fabricated by conjugating indocyanine green (ICG) on hollow gold nanospheres (HAuNS) using branched-polyethylenimine (PEI, MW = 10 kDa) as optimal linker, which provided a high ICG payload as well as a covering layer with suitable thickness on HAuNS to maintain ICG fluorescence and reactive oxygen species (ROS) productivity. The resulting system (ICG-PEI-HAuNS) had the molar ratio of ICG:PEI:Au = 3:0.33:5. Compared with free ICG, ICG-PEI-HAuNS exhibited dramatically enhanced stability of ICG molecules and greater intratumoral accumulation. The conjugation of ICG caused significantly higher plasmon absorption of ICG-PEI-HAuNS in the NIR region compared with HAuNS alone, inducing remarkably enhanced photothermal conversion efficiency and synchronous photodynamic effect under NIR light irradiation. Interestingly, compared with PTT or PDT alone, synchronous PTT and PDT produced by ICG-PEI-HAuNS upon NIR light irradiation induced significantly stronger antitumor and metastasis inhibition effects both in vitro and in vivo, which might be a promising strategy for cancer treatment.

Abstract
Many photoresponsive dyes have been utilized as imaging and photodynamic/photothermal therapy agents. Indocyanine green (ICG) is the only near-infrared region (NIR) organic dye for clinical applications approved by the United States Food and Drug Administration; however, the clinical application of ICG is limited by its poor aqueous solubility, low cancer specificity, and low sensitivity in cancer theranostics. To overcome these issues, a multifunctional nanoplatform based on hyaluronic acid (HA) and ICG-engineered metal-organic framework MIL-100(Fe) nanoparticles (MOF@HA@ICG NPs) was successfully developed for imaging-guided, anticancer photothermal therapy (PTT). The synthesized NPs showed a high loading content of ICG (40%), strong NIR absorbance, and photostability. The in vitro and in vivo imaging showed that the MOF@HA@ICG NPs exhibited greater cellular uptake in CD44-positive MCF-7 cells and enhanced tumor accumulation in xenograft tumors due to their targeting capability, compared to MOF@ICG NPs (non-HA-targeted) and free ICG. The in vitro photothermal toxicity and in vivo PTT treatments demonstrated that MOF@HA@ICG NPs could effectively inhibit the growth of MCF-7 cells/xenograft tumors. These results suggest that MOF@HA@ICG NPs could be served as a new promising theranostic nanoplatform for improved anticancer PTT through cancer-specific and image-guided drug delivery.

Abstract
Light-activated theranostic materials offer a potential platform for optical imaging and phototherapeutic applications. We have engineered constructs derived from erythrocytes, which can be doped with the FDA-approved near infrared (NIR) chromophore, indocyanine green (ICG). We refer to these constructs as NIR erythrocyte-mimicking transducers (NETs). Herein, we investigated the effects of changing the NETs mean diameter from micron- (≈4 μm) to nano- (≈90 nm) scale, and the ICG concentration utilized in the fabrication of NETs from 5 to 20 μM on the resulting absorption and scattering characteristics of the NETs. Our approach consisted of integrating sphere-based measurements of light transmittance and reflectance, and subsequent utilization of these measurements in an inverse adding-doubling algorithm to estimate the absorption (μ a) and reduced scattering (μ s') coefficients of these NETs. For a given NETs diameter, values of μ a increased over the approximate spectral band of 630-860 nm with increasing ICG concentration. Micron-sized NETs produced the highest peak value of μ a when using ICG concentrations of 10 and 20 μM, and showed increased values of μ s' as compared to nano-sized NETs. Spectral profiles of μ s' for these NETs showed a trend consistent with Mie scattering behavior for spherical objects. For all NETs investigated, changing the ICG concentration minimally affected the scattering characteristics. A Monte Carlo-based model of light distribution showed that the presence of these NETs enhanced the fluence levels within simulated blood vessels. These results provide important data towards determining the appropriate light dosimetry parameters for an intended light-based biomedical application of NETs.

Abstract
Photoacoustic (PA)/near-infrared fluorescence (NIRF) dual-modal imaging-guided phototherapy has been wide explored very recently. However, the development of high-efficiency and simplified-performed theranostic system for amplifying imaging-guided photothermal therapy/photodynamic therapy (PTT/PDT) is still a great challenge. Herein, a single-light-triggered indocyanine green (ICG)-loaded PEGylation silver nanoparticle core/polyaniline shell (Ag@PANI) nanocomposites (ICG-Ag@PANI) for PA/NIRF imaging-guided enhanced PTT/PDT synergistic effect has been successfully constructed. In this study, the synthesized Ag@PANI nanocomposites are utilized not only as the promising photothermal agent but also as potential nanovehicles for loading photosensitizer ICG via π-π stacking and hydrophobic interaction. The as-prepared ICG-Ag@PANI possesses many superior properties such as strong optical absorption in the near-infrared (NIR) region, enhanced photostability of ICG, as well as outstanding NIR laser-induced local hyperthermia and reactive oxygen species (ROS) generation. In the in vivo study, PA/NIRF dual-modal imaging confirms the accumulation and distribution of ICG-Ag@PANI in the tumor region via enhanced permeability and retention (EPR) effect. Moreover, the PTT effect of ICG-Ag@PANI rapidly raised the tumor temperature to 56.8 °C within 5 min. It is also demonstrated that the cytotoxic ROS generation ability of ICG is well maintained after being loaded onto Ag@PANI nanocomposites. Remarkably, in comparison with PTT or PDT alone, the single 808 nm NIR laser-triggered combined PTT/PDT therapy exhibits enhanced HeLa cells lethality in vitro and tumor growth inhibition in vivo.

Abstract
An active cell membrane-camouflaged nanoparticle, owning to membrane antigens and membrane structure, can achieve special properties such as specific recognition, long blood circulation, and immune escaping. Herein, we reported a cancer cell membrane-cloaked nanoparticle system as a theranostic nanoplatform. The biomimetic nanoparticles (indocyanine green (ICG)-loaded and cancer cell membrane-coated nanoparticles, ICNPs) exhibit a core-shell nanostructure consisting of an ICG-polymeric core and cancer cell membrane shell. ICNPs demonstrated specific homologous targeting to cancer cells with good monodispersity, preferable photothermal response, and excellent fluorescence/photoacoustic (FL/PA) imaging properties. Benefited from the functionalization of the homologous binding adhesion molecules from cancer cell membranes, ICNPs significantly promoted cell endocytosis and homologous-targeting tumor accumulation in vivo. Moreover, ICNPs were also good at disguising as cells to decrease interception by the liver and kidney. Through near-infrared (NIR)-FL/PA dual-modal imaging, ICNPs could realize real-time monitored in vivo dynamic distribution with high spatial resolution and deep penetration. Under NIR laser irradiation, ICNPs exhibited highly efficient photothermal therapy to eradicate xenografted tumor. The robust ICNPs with homologous properties of cancer cell membranes can serve as a bionic nanoplatform for cancer-targeted imaging and phototherapy.

Abstract
We have prepared novel poly(d,l-lactide-co-glycolide) (PLGA) lipid nanoparticles (PNPs) that covalently conjugate folic acid (FA) and indocyanine green (ICG), in addition to encapsulating resveratrol (RSV) (FA-RSV/ICG-PLGA-lipid NPs, abbreviated as FA-RIPNPs); these nanoparticles have been developed for simultaneous targeted delivery of anticancer drug and fluorescence imaging. The FA-RIPNPs, with an average particle size of 92.8±2.1 nm, were prepared by a facile self-assembly-and-nanoprecipitation method, and they showed excellent stability and biocompatibility characteristics. The FA-RIPNPs exhibited an RSV encapsulation efficiency of approximately 65.6%±4.7% and a maximum release ratio of 78.2%±4.1% at pH 5.0 and 37°C. Confocal fluorescence images showed that FA-RIPNPs may facilitate a high cellular uptake via FA receptor-mediated endocytosis. Furthermore, FA-RIPNPs (containing 50 μg/mL RSV) induced a 81.4%±2.1% U87 cell inhibition rate via apoptosis, a value that proved to be higher than what has been shown for free RSV (53.1%±1.1%, equivalent RSV concentration). With a formulated polyethylene glycol (PEG) shell around the PLGA core, FA-RIPNPs prolonged the blood circulation of both free RSV and ICG, which approximately increased 6.96- and 39.4-fold (t1/2), respectively. Regarding FA-RIPNP use as a near-infrared probe, in vivo fluorescence images indicated a highly efficient accumulation of FA-RIPNPs in the tumor tissue, which proved to be approximately 2.8- and 12.6-fold higher than the RIPNPs and free ICG, respectively. Intravenous injection of FA-RIPNPs into U87 tumor-bearing mice demonstrated the best tumor inhibition effect for all tested drugs, including free RSV and RIPNPs, with no relapse, showing high biocompatibility and with no significant systemic in vivo toxicity over the course of the treatment (1 month). The results obtained demonstrate the versatility of the NPs, featuring stable fluorescence and tumor-targeting characteristics, with promising future applications in cancer therapy.

Abstract
"On-demand" drug release within target site is critical for targeted drug delivery systems. We herein integrate the advantages of upper critical solution temperature (UCST) polymers, photothermal agent, and red blood cell (RBC) membrane coating into a single drug delivery nanosystem and, for the first time, achieve remotely controlled UCST polymer-based drug delivery system that undergoes "on-demand" drug release within specified zone. When in laser-off state, the resulting nanosystem demonstrates significantly diminished drug self-leakage, owing to shielding by the RBC membrane coating. Upon laser irradiation, this system undergoes responsive drug release, likely because of particle swelling due to its UCST polymer component's hydrophobic-to-hydrophilic transition triggered by the rapid localized heating generated by its preloaded photothermal agent via photothermal effects. As a result, this drug delivery system exhibits spatiotemporally controlled cytotoxicity to cultured cells, efficiently eradicating irradiated cancerous cells without appreciably impacting nonirradiated ones, those ∼0.7 cm away from the irradiation zone. This work may open an avenue to thermosensitive drug delivery systems potentially "ideal" for intravenous administration and inspire future efforts on biomedical applications of UCST polymers.

Abstract
UNLABELLED Although indocyanine green (ICG) has promising applications in photothermal therapy (PPT) because of its low toxicity and high efficiency in inducing heat and singlet oxygen formation in response to near-infrared light with a wavelength of approximately 800nm, its clinical application has been restricted because of its rapid body clearance and poor water stability. Therefore, cell membrane capsules (CMCs) derived from mammalian cells were used to encapsulate negatively charged ICG by temporarily permeating the plasma membrane and resealing using positively charged doxorubicin hydrochloride (DOX). The resulting CMCs@DOX/ICG exhibited a spherical shape, with a diameter of approximately 800nm. The DOX and ICG encapsulation was confirmed by the UV-vis spectrum; a very small amount of DOX (0.8μg) and a very high amount of ICG (∼110μg) were encapsulated in 200μg CMCs. Encapsulation in the CMCs leads to sustained release of ICG, especially in the presence of positively charged DOX. The temperature enhancement and generation of ROS by ICG encapsulated in CMCs were confirmed upon laser irradiation in vitro, leading to cell death. CMCs@DOX/ICG also can significantly enhance the retention of ICG in a tumor after intratumoral injection in vivo. As a result, combination treatment with CMCs@DOX/ICG and laser irradiation demonstrated much better anticancer efficacy than that of free DOX/ICG and CMCs@ICG. The encapsulation of ICG into CMCs, especially with the assistance of DOX, significantly slows down the body clearance of ICG, with a retained PPT effect against tumors, an important step forward in the practical application of ICG in cancer therapy. STATEMENT OF SIGNIFICANCE In this study, cell membrane capsules (CMCs) derived from mammalian cells were used to encapsulate negatively charged indocyanine green (ICG) by temporarily permeating the plasma membrane and resealing, in the presence of positively charged doxorubicin hydrochloride (DOX). The resulting CMCs@DOX/ICG exhibited a spherical shape, with a diameter of approximately 800nm. Encapsulation in the CMCs leads to sustained release of ICG and thus slower clearance inside body, especially in the presence of positively charged DOX. The system provides a better photothermal effect against tumors, an important step forward in the practical application of ICG in cancer therapy.

Abstract
Combination of photodynamic therapy (PDT) with photothermal therapy (PTT) has achieved significantly improved therapeutic efficacy compared to a single phototherapy modality. However, most nanomaterials used for combined PDT/PTT are made of non-biodegradable materials (e.g., gold nanorods, carbon nanotubes, and graphenes) and may remain intact in the body for long time, raising concerns over their potential long-term toxicity. Here we report a new combined PDT/PTT nanomedicine, designated SP3NPs, that exhibit photo-decomposable, photodynamic and photothermal properties. SP3NPs were prepared by self-assembly of PEGylated cypate, comprising FDA-approved PEG and an ICG derivative. We confirmed the ability of SP3NPs to generate both singlet oxygen for a photodynamic effect and heat for photothermal therapy in response to NIR laser irradiation in vitro. Also, the unique ability of SP3NPs to undergo irreversible decomposition upon NIR laser irradiation was demonstrated. Further our experimental results demonstrated that SP3NPs strongly accumulated in tumor tissue owing to their highly PEGylated surface and relatively small size (~60 nm), offering subsequent imaging-guided combined PDT/PTT treatment that resulted in tumor eradication and prolonged survival of mice. Taken together, our SP3NPs described here may represent a novel and facile approach for next-generation theranostics with great promise for translation into clinical practice in the future.

Abstract
Near-infrared (NIR) fluorescent nanostructured materials have emerged as novel contrast agents for non-invasive bioimaging. Here we report a class of polymer-silica nanoparticles doped with a NIR fluorescent dye prepared through a facile one-pot strategy. Hydrophobic NIR fluorescent dyes such as IR 780 iodide could be easily encapsulated into the micellar core by self-assembly of amphiphilic triblock copolymer Pluronic F127. When subsequently adding silane in aqueous solution, nanoparticles with a cross-linked core and a hydrophilic PEG shell were formed. The structure of the as-obtained nanoparticles was confirmed by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The nanoparticles exhibited a well-defined spherical structure with a mean diameter of approximately 30 nm, and excellent monodispersity and stability in aqueous solution. In addition, the photo-stability of IR 780 was significantly improved by encapsulation into the nanoparticles. In vitro MTT assay with cell lines HEK293 and A431 demonstrated that the IR 780 loaded nanoparticles (termed as IR780@NPs) were biocompatible. In vivo sentinel lymph node imaging revealed that the fluorescent intensity and retention time of the IR780@NPs were clearly superior to its constituent free dye, making it amenable to in vivo bioimaging. Further in vivo tumor imaging indicated that IR780@NPs have a longer retention time and much higher accumulation on the tumor site compared to free dye after intravenous administration. Overall this hydrophilic NIR fluorescent contrast agent exhibits excellent photophysical characteristics and low cytotoxicity, and holds a strong promise for a variety of applications including bioimaging and therapy.

Abstract
A novel and green multifunctional nanoplatform as a nanocarrier for drug delivery, cell imaging, and phototherapy has been engineered. The nanoplatform is composed of stabilized carbon spheres (CSs) as cores, a coated polydopamine (PDA) shell, targeted folic acid (FA), and the loaded anticancer drug indocyanine green (ICG), obtaining CSs@PDA-FA@ICG nanocomposites (NCs). The biocompatible PDA shell provided a high fluorescence quenching efficiency and a surface rich in functional groups for anchoring FA for targeting cancer cells. Aromatic ICG could be effectively loaded into the CSs@PDA-FA system via hydrophobic interactions and π-π stacking with a loading efficiency of 58.9%. Notably, the activated NIR fluorescence in an intracellular environment made CSs@PDA-FA@ICG a sensitive "OFF" to "ON" nanoprobe that can be used for NIR imaging. Moreover, compared to ICG alone, the CSs@PDA-FA@ICG NCs could induce efficient photoconversion for simultaneous synergetic photodynamic therapy (PDT) and photothermal therapy (PTT) under a single NIR laser irradiation. The results demonstrated that CSs@PDA-FA@ICG NCs as a targeted and activated nanoplatform provide new opportunities to facilitate the accurate diagnosis of cancer and enhanced treatment efficacy. This work stimulates more interest in the design of the facile surface functionalization strategy to construct other multifunctional nanocomposites, such as nanotubes and nanorods.

Abstract
The development of treatment protocols that resulted in a complete response to photothermal therapy (PTT) was usually hampered by uneven heat distribution and low effectiveness. Here, we reported an NIR fluorescence and photoacoustic dual-modal imaging-guided active targeted thermal sensitive liposomes (TSLs) based on the photothermal therapy agent Indocyanine green (ICG) and antiangiogenesis agent Rapamycin (RAPA) to realize enhanced therapeutic and diagnostic functions. As expected, the in vitro drug release studies exhibited the satisfactory result of drug released from the TSLs under hyperthermia conditions induced by NIR stimulation. The in vitro cellular studies confirmed that the FA-ICG/RAPA-TSLs plus NIR laser exhibited efficient drug accumulation and cytotoxicity in tumor cells and epithelial cells. After 24 h intravenous injection of FA-ICG/RAPA-TSLs, the margins of tumor and normal tissue were accurately identified via the in vivo NIR fluorescence and photoacoustic dual-modal imaging. In addition, FA-ICG/RAPA-TSLs combined with NIR irradiation treated tumor-bearing nude mice inhibited tumor growth to a great extent and possessed much lower side effects to normal organs. All detailed evidence suggested that the theranostic TSLs which were capable of enhancing the therapeutic index might be a suitable drug delivery system for dual-modal imaging-guided therapeutic tools for diagnostics as well as the treatment of tumors.

Abstract
Indocyanine green (ICG) is a cyanine compound that displays fluorescent properties in the near infrared region. This dye is employed for numerous indications but nowadays its major application field regards tumour diagnosis and treatments. Optical imaging by near infrared fluorescence provides news opportunities for oncologic surgery. The imaging of ICG can be useful for intraoperative identification of several solid tumours and metastases, and sentinel lymph node detection. In addition, ICG can be used as an agent for the destruction of malignant tissue, by virtue of the production of reactive oxygen species and/or induction of a hyperthermia effect under irradiation. Nevertheless, ICG shows several drawbacks, which limit its clinical application. Several formulative strategies have been studied to overcome these problems. The rationale of the development of ICG containing drug delivery systems is to enhance the in vivo stability and biodistribution profile of this dye, allowing tumour accumulation and resulting in better efficacy. In this review, ICG containing nano-sized carriers are classified based on their chemical composition and structure. In addition to nanosystems, different formulations including hydrogel, microsystems and others loaded with ICG will be illustrated. In particular, this report describes the preparation, in vitro characterization and in vivo application of ICG platforms for cancer imaging and treatment. The promising results of all systems confirm their clinical utility but further studies are required prior to evaluating the formulations in human trials.

Abstract
IR-780 iodide, a near-infrared (near-IR) fluorescent dye, can be utilized as an effective theranostic agent for both imaging and photothermal therapy. However, its lipophilicity limits its further biomedical applications. Herein, we synthesized a phospholipid mimicking amphiphilic homopolymer poly(12-(methacryloyloxy)dodecyl phosphorylcholine) (PMDPC) via reversible addition-fragmentation chain transfer (RAFT) polymerization. The amphiphilic homopolymer PMDPC can be self-assembled into micelles and used for the encapsulation of IR-780. The IR-780 loaded micelles (PMDPC-IR-780) exhibited low cytotoxicity in the dark, whereas remarkable photothermal cytotoxicity to pancreatic cancer cells (BxPC-3) was observed upon near-IR laser irradiation. We further investigated in vivo biodistribution of PMDPC-IR-780 micelles. Higher accumulation of PMDPC-IR-780 than that of free IR-780 in tumor tissue was verified, which might be ascribed to the enhanced permeability and retention (EPR) effect and long circulation time benefiting from the zwitterionic phosphorylcholine surface. Therefore, the IR-780 loaded phospholipid mimicking homopolymeric micelles could have great potential for cancer theranostics.

Abstract
The challenge in photothermal therapy (PTT) is to develop biocompatible photothermal transducers that can absorb and convert near-infrared (NIR) light into heat with high efficiency. Herein, we report salt-induced aggregation of gold nanoparticles (GNPs) in biological media to form highly efficient and biocompatible NIR photothermal transducers for PTT and photothermal/photoacoustic (PT/PA) imaging of cancer. The GNP depots in situ formed by salt-induced aggregation of GNPs show strong NIR absorption induced by plasmonic coupling between adjacent GNPs and very high photothermal conversion efficiency (52%), enabling photothermal destruction of tumor cells. More interestingly, GNPs in situ aggregate in tumors to form GNP depots, enabling simultaneous PT/PA imaging and PTT of the tumors. These findings may provide a simple and effective way to develop a new class of intelligent and biocompatible NIR photothermal transducers with high efficiency for PT/PA imaging and PTT.

Abstract
Photoacoustic imaging (PAI) is an emerging analytical modality that is under intense preclinical development for the early diagnosis of various medical conditions, including cancer. However, the lack of specific tumor targeting by various contrast agents used in PAI obstructs its clinical applications. In this study, we developed indocyanine green (ICG)-encapsulated micelles specific for the CD 44 receptor and used in near infrared and photoacoustic imaging of tumors. ICG was hydrophobically modified prior to loading into hyaluronic acid (HA)-based micelles utilized for CD 44 based-targeting. We investigated the physicochemical characteristics of prepared HA only and ICG-encapsulated HA micelles (HA-ICG micelles). After intravenous injection of tumor-bearing mice, the bio-distribution and in vivo photoacoustic images of ICG-encapsulated HA micelles accumulating in tumors were also investigated. Our study further encourages the application of this HA-ICG-based nano-platform as a tumor-specific contrast agent for PAI.

Abstract
A biodegradable and reduction-cleavable gemcitabine (GEM) polymeric prodrug with in vivo near-infrared (NIR) imaging ability was reported. This theranostic GEM prodrug PEG-b-[PLA-co-PMAC-graft-(IR820-co-GEM)] was synthesized by ring-opening polymerization and "click" reaction. The as-prepared reduction-sensitive prodrug could self-assemble into prodrug micelles in aqueous solution confirmed by dynamic light scattering (DLS) and transmission electron microscopy (TEM). In vitro drug release studies showed that these prodrug micelles were able to release GEM in an intracellular-mimicking reductive environment. These prodrug micelles could be effectively internalized by BxPC-3 pancreatic cancer cells, which were observed by confocal laser scanning microscopy (CLSM). Meanwhile, a methyl thiazolyl tetrazolium (MTT) assay demonstrated that this prodrug exhibited high cytotoxicity against BxPC-3 cells. The in vivo whole-animal near-infrared (NIR) imaging results showed that these prodrug micelles could be effectively accumulated in tumor tissue and had a longer blood circulation time than IR820-COOH. The endogenous reduction-sensitive gemcitabine prodrug micelles with the in vivo NIR imaging ability might have great potential in image-guided pancreatic cancer therapy.

Abstract
To significantly promote tumor uptake and penetration of therapeutics, a nanovehicle system comprising poly(lactic-co-glycolic acid) (PLGA) as the hydrophobic cores coated with pH-responsive N-acetyl histidine modified D-α-tocopheryl polyethylene glycol succinate (NAcHis-TPGS) is developed in this work. The nanocarriers with switchable surface charges in response to tumor extracellular acidity (pHe) were capable of selectively co-delivering indocyanine green (ICG), a photothermal agent, and doxorubicin (DOX), a chemotherapy drug, to tumor sites. The in vitro cellular uptake of ICG/DOX-loaded nanoparticles by cancer cells and macrophages was significantly promoted in weak acidic environments due to the increased protonation of the NAcHis moieties. The results of in vivo and ex vivo biodistribution studies demonstrated that upon intravenous injection the theranostic nanoparticles were substantially accumulated in TRAMP-C1 solid tumor of tumor-bearing mice. Immunohistochemical examination of tumor sections confirmed the active permeation of the nanoparticles into deep tumor hypoxia due to their small size, pHe-induced near neutral surface, and the additional hitchhiking transport via tumor-associated macrophages. The prominent imaging-guided photothermal therapy of ICG/DOX-loaded nanoparticles after tumor accumulation induced extensive tumor tissue/vessel ablation, which further promoted their extravasation and DOX tumor permeation, thus effectively suppressing tumor growth.

Abstract
Multifunctional near-infrared (NIR) nanoparticles demonstrate great potential in tumor theranostic applications. To achieve the sensitive detection and effective phototherapy in the early stage of tumor genesis, it is highly desirable to improve the targeting of NIR theranostic agents to biomarkers and to enhance their accumulation in tumor. Here we report a novel targeted multifunctional theranostic nanoparticle, internalized RGD (iRGD)-modified indocyanine green (ICG) liposomes (iRGD-ICG-LPs), for molecular imaging-guided photothermal therapy (PTT) and photodynamic therapy (PDT) therapy against breast tumor. The iRGD peptides with high affinity to αvβ3 integrin and effective tumor-internalized property were firstly used to synthesize iRGD-PEG2000-DSPE lipopeptides, which were further utilized to fabricate the targeted ICG liposomes. The results indicated that iRGD-ICG-LPs exhibited excellent stability and could provide an accurate and sensitive detection of breast tumor through NIR fluorescence molecular imaging. We further employed this nanoparticle for tumor theranostic application, demonstrating significantly higher tumor accumulation and tumor inhibition efficacy through PTT/PDT effects. Histological analysis further revealed much more apoptotic cells, confirming the advantageous anti-tumor effect of iRGD-ICG-LPs over non-targeted ICG-LPs. Notably, the targeting therapy mediated by iRGD provides almost equivalent anti-tumor efficacy at a 12.5-fold lower drug dose than that by monoclonal antibody, and no tumor recurrence and obvious treatment-induced toxicity were observed in our study. Our study provides a promising strategy to realize the sensitive detection and effective treatment of tumors by integrating molecular imaging into PTT/PDT therapy.

Abstract
Despite the tremendous progress that photothermal therapy (PTT) has recently achieved, it still has a long way to go to gain the effective targeted photothermal ablation of tumor cells. Driven by this need, we describe a new class of targeted photothermal therapeutic agents for cancer cells with pH responsive bioimaging using near-infrared dye (NIR) IR825, conjugated poly(ethylene glycol)-g-poly(dimethylaminoethyl methacrylate) (PEG-g-PDMA, PgP), and hyaluronic acid (HA) anchored reduced graphene oxide (rGO) hybrid nanoparticles. The obtained rGO nanoparticles (PgP/HA-rGO) showed pH-dependent fluorescence emission and excellent near-infrared (NIR) irradiation of cancer cells targeted in vitro to provide cytotoxicity. Using intravenously administered PTT agents, the time-dependent in vivo tumor target accumulation was exactly defined, presenting eminent photothermal conversion at 4 and 8 h post-injection, which was demonstrated from the ex vivo biodistribution of tumors. These tumor environment responsive hybrid nanoparticles generated photothermal heat, which caused dominant suppression of tumor growth. The histopathological studies obtained by H&E staining demonstrated complete healing from malignant tumor. In an area of limited successes in cancer therapy, our translation will pave the road to design stimulus environment responsive targeted PTT agents for the safe eradication of devastating cancer.

Abstract
The therapeutic effectiveness of chemotherapy was hampered by dose-limiting toxicity and was optimal only when tumor cells were subjected to a maximum drug exposure. The purpose of this work was to design a dual-functional thermosensitive bubble-generating liposome (BTSL) combined with conjugated targeted ligand (folate, FA) and photothermal agent (IR780), to realize enhanced therapeutic and diagnostic functions. This drug carrier was proposed to target tumor cells owing to FA-specific binding, followed by triggering drug release due to the decomposition of encapsulated ammonium bicarbonate (NH4HCO3) (generated CO2 bubbles) by being subjected to near-infrared (near-IR) laser irradiation, creating permeable defects in the lipid bilayer that rapidly release drug. In vitro temperature-triggered release study indicated the BTSL system was sensitive to heat triggering, resulting in rapid drug release under hyperthermia. For in vitro cellular uptake experiments, different results were observed on human epidermoid carcinoma cells (KB cells) and human lung cancer cells (A549 cells) due to their different (positive or negative) response to FA receptor. Furthermore, in vivo biodistribution analysis and antitumor study indicated IR780-BTSL-FA could specifically target KB tumor cells, exhibiting longer circulation time than free drug. In the pharmacodynamics experiments, IR780-BTSL-FA efficiently inhibited tumor growth in nude mice with no evident side effect to normal tissues and organs. Results of this study demonstrated that the constructed smart theranostic nanocarrier IR780-BTSL-FA might contribute to establishment of tumor-selective and effective chemotherapy.

Abstract
Although many techniques exist for fabricating near-infrared (NIR)-resonant and magnetic resonance imaging (MRI)-capable nanomediators for photothermal cancer therapy, preparing them in an efficient and scalable process remains a significant challenge. In this report, we exploit one-step siloxane chemistry to facilely conjugate NIR-absorbing satellites onto a well-developed polysiloxane-containing polymer-coated iron oxide nanoparticle (IONP) core to generate dual functional core-satellite nanomediators for photothermal therapy. An advantage of this nanocomposite design is the variety of potential satellites that can be simply attached to impart NIR resonance, which we demonstrate using NIR-resonant gold sulfide nanoparticles (Au2SNPs) and the NIR dye IR820 as two example satellites. The core-satellite nanomediators are fully characterized by using absorption spectra, dynamic light scattering, ζ potential measurements, and transmission electron microscopy. The enhanced photothermal effect under the irradiation of NIR laser light is identified through in vitro solutions and in vivo mice studies. The MRI capabilities as contrast agents are demonstrated in mice. Our data suggest that polysiloxane-containing polymer-coated IONPs can be used as a versatile platform to build such dual functional nanomediators for translatable, MRI-guided photothermal cancer therapy.

Abstract
Indocyanine green (ICG), an FDA approved medical near-infrared (NIR) imaging agent, has been extensively used in cancer theranosis. However, the limited aqueous photostability, rapid body clearance, and poor cellular uptake severely restrict its practical applications. For these problems to be overcome, ICG-encapsulated hybrid polymeric nanomicelles (PNMs) were developed in this work through coassociation of the amphiphilic diblock copolymer poly(lactic-co-glycolic acid)-b-poly(ethylene glycol) (PLGA-b-PEG) and hydrophobic electrostatic complexes composed of ICG molecules and branched poly(ethylenimine) (PEI). The ICG-encapsulated hybrid PNMs featured a hydrophobic PLGA/ICG/PEI core stabilized by hydrophilic PEG shells. The encapsulation of electrostatic ICG/PEI complexes into the compact PLGA-rich core not only facilitated the ICG loading but also promoted its aqueous optical stability. The effects of the chain length of PEI in combination with ICG on the physiochemical properties of PNMs and their drug leakage were also investigated. PEI(10k) (10 kDa) could form highly robust and dense complexes with ICG, and thus prominently reduced ICG outflow from the PNMs. The results of in vitro cellular uptake and cytotoxicity studies revealed that the ICG/PEI(10k)-loaded PNMs significantly promoted cellular uptake of ICG by HeLa cells due to their near-neutral surface, and thereby augmented the NIR-triggered hyperthermia effect in destroying cancer cells. These findings strongly indicate that the ICG/PEI10k-loaded PNMs have significant potential for attaining effective cancer imaging and photothermal therapy.

Abstract
Pancreatic cancer is an insidious type of cancer with its symptoms manifested upon extensive disease. The overall 5-year survival rates between 0.4 and 4%. Surgical resection is an option for only 10% of the patients with pancreatic cancer. Local recurrence and hepatic metastases occur within 2 years after surgery. There are currently several molecular pathways investigated and novel targeted treatments are on the market. However; the nature of pancreatic cancer with its ability to spread locally in the primary site and lymph nodes indicates that further experimentation with local interventional therapies could be a future treatment proposal as palliative care or adjunct to gene therapy and chemotherapy/radiotherapy. In the current review, we will summarize the molecular pathways and present the interventional treatment options for pancreatic cancer.

Abstract
IR-780, a representative hydrophobic near-infrared (NIR) fluorescence dye, is capable of fluorescently imaging and photothermal therapy in vitro and in vivo. However, insolubility in all pharmaceutically acceptable solvents limits its further biological applications. To increase solubility, we developed a novel self-assembled IR-780 containing micelle (PEG-IR-780-C13) based on the structural modification of IR-780. Briefly, a hydrophilic PEG2000 was modified on the one side of IR-780, and the hydrophobic carbon chain on the other side was extended from C3 to C16 (additional C13 carbon chain). The modification provides a better self-assemble capability, improved water solubility and higher stability. In addition, PEG-IR-780-C13 micelles are specifically targeted to the tumor after intravenous injection and can be used for tumor imaging. The in vitro cell viability assays and in vivo photothermal therapy experiments indicated that CT-26 cells or CT-26 xenograft tumors can be effectively ablated by combining PEG-IR-780-C13 micelles with 808 nm laser irradiation. More importantly, no significant toxicity can be observed after intravenous administration of the therapeutic dose of generated micelles. Overall, our micelles may have the least safety concern while showing excellent treatment efficacy, and thus may be a new photothermal agent potentially useful in clinical applications.

Abstract
Aim: Indocyanine green (ICG) is a promising near-infrared (NIR) dye for tumor imaging and photothermal therapy; however, the poor stability and lack of targeting limit its application. In this study, ICG was encapsulated into folate-conjugated poly(2-ethyl-2-oxazoline)-b-poly(ε-caprolactone) micelles to overcome these problems. Materials & methods: ICG-loaded micelles were prepared by solvent evaporation method. Cell uptake and in vitro photothermal cytotoxicity were evaluated on KB cells. In vivo NIR imaging and photothermal therapy were conducted on KB tumor-bearing mice. Results: ICG-loaded micelles with favorable sizes and stable NIR optical properties were successfully prepared. These micelles could target to KB tumors and enabled high-resolution NIR imaging. Moreover, they could effectively convert the absorbed NIR laser energy into heat, resulting in significant tumor damage and inhibition. Conclusion: This novel micellar system, integrating stable NIR properties, excellent tumor targeting and photothermal capability, showed great potential in tumor imaging and therapy.

Abstract
Near-infrared plasmonic nanoparticles demonstrate great potential in disease theranostic applications. Herein a nanoplatform, composed of mesoporous silica-coated gold nanorods (AuNRs), is tailor-designed to optimize the photodynamic therapy (PDT) for tumor based on the plasmonic effect. The surface plasmon resonance of AuNRs was fine-tuned to overlap with the exciton absorption of indocyanine green (ICG), a near-infrared photodynamic dye with poor photostability and low quantum yield. Such overlap greatly increases the singlet oxygen yield of incorporated ICG by maximizing the local field enhancement, and protecting the ICG molecules against photodegradation by virtue of the high absorption cross section of the AuNRs. The silica shell strongly increased ICG payload with the additional benefit of enhancing ICG photostability by facilitating the formation of ICG aggregates. As-fabricated AuNR@SiO2-ICG nanoplatform enables trimodal imaging, near-infrared fluorescence from ICG, and two-photon luminescence/photoacoustic tomography from the AuNRs. The integrated strategy significantly improved photodynamic destruction of breast tumor cells and inhibited the growth of orthotopic breast tumors in mice, with mild laser irradiation, through a synergistic effect of PDT and photothermal therapy. Our study highlights the effect of local field enhancement in PDT and demonstrates the importance of systematic design of nanoplatform to greatly enhancing the antitumor efficacy.

Abstract
Gold nanocages (AuNCs), which have tunable near-infrared (NIR) absorption and intrinsically high photothermal conversion efficiency, have been actively investigated as photothermal conversion agents for photothermal therapy (PTT). The short blood circulation lifetime of AuNCs, however, limits their tumor uptake and thus in vivo applications. Here we show that such a limitation can be overcome by cloaking AuNCs with red blood cell (RBC) membranes, a natural stealth coating. The fusion of RBC membranes over AuNC surface does not alter the unique porous and hollow structures of AuNCs, and the resulting RBC-membrane-coated AuNCs (RBC-AuNCs) exhibit good colloidal stability. Upon NIR laser irradiation, the RBC-AuNCs demonstrate in vitro photothermal effects and selectively ablate cancerous cells within the irradiation zone as do the pristine biopolymer-stealth-coated AuNCs. Moreover, the RBC-AuNCs exhibit significantly enhanced in vivo blood retention and circulation lifetime compared to the biopolymer-stealth-coated counterparts, as demonstrated using a mouse model. With integrated advantages of photothermal effects from AuNCs and long blood circulation lifetime from RBCs, the RBC-AuNCs demonstrate drastically enhanced tumor uptake when administered systematically, and mice that received PPT cancer treatment modulated by RBC-AuNCs achieve 100% survival over a span of 45 days. Taken together, our results indicate that the long circulating RBC-AuNCs may facilitate the in vivo applications of AuNCs, and the RBC-membrane stealth coating technique may pave the way to improved efficacy of PPT modulated by noble metal nanoparticles.

Abstract
In medicine, nanotechnology has sparked a rapidly growing interest as it promises to solve a number of issues associated with conventional therapeutic agents, including their poor water solubility (at least, for most anticancer drugs), lack of targeting capability, nonspecific distribution, systemic toxicity, and low therapeutic index. Over the past several decades, remarkable progress has been made in the development and application of engineered nanoparticles to treat cancer more effectively. For example, therapeutic agents have been integrated with nanoparticles engineered with optimal sizes, shapes, and surface properties to increase their solubility, prolong their circulation half-life, improve their biodistribution, and reduce their immunogenicity. Nanoparticles and their payloads have also been favorably delivered into tumors by taking advantage of the pathophysiological conditions, such as the enhanced permeability and retention effect, and the spatial variations in the pH value. Additionally, targeting ligands (e.g., small organic molecules, peptides, antibodies, and nucleic acids) have been added to the surface of nanoparticles to specifically target cancerous cells through selective binding to the receptors overexpressed on their surface. Furthermore, it has been demonstrated that multiple types of therapeutic drugs and/or diagnostic agents (e.g., contrast agents) could be delivered through the same carrier to enable combination therapy with a potential to overcome multidrug resistance, and real-time readout on the treatment efficacy. It is anticipated that precisely engineered nanoparticles will emerge as the next-generation platform for cancer therapy and many other biomedical applications.
