Abstract
Fluorescence and photoacoustic imaging have different advantages in cancer diagnosis; however, combining effects in one agent normally requires a trade-off as the mechanisms interfere. Here, based on rational molecular design, we introduce a smart organic nanoparticle whose absorbed excitation energy can be photo-switched to the pathway of thermal deactivation for photoacoustic imaging, or to allow opposed routes for fluorescence imaging and photodynamic therapy. The molecule is made of a dithienylethene (DTE) core with two surrounding 2-(1-(4-(1,2,2-triphenylvinyl)phenyl)ethylidene)malononitrile (TPECM) units (DTE-TPECM). The photosensitive molecule changes from a ring-closed, for photoacoustic imaging, to a ring-opened state for fluorescence and photodynamic effects upon an external light trigger. The nanoparticles’ photoacoustic and fluorescence imaging properties demonstrate the advantage of the switch. The use of the nanoparticles improves the outcomes of in vivo cancer surgery using preoperative photoacoustic imaging and intraoperative fluorescent visualization/photodynamic therapy of residual tumours to ensure total tumour removal. The combination of imaging techniques in cancer treatment often involves a trade-off in properties due to the opposite working mechanisms. Here, the authors report on a material that avoids the trade-off by switching from photoacoustic imaging to fluorescence imaging upon an external light trigger

Abstract
As phototheranostic agents, carbon dots (CDs), have recently drawn considerable attention due to their excellent physicochemical properties. However, the complex synthetic route and high-cost of CDs greatly limit their practical application. To address this issue, given their nearly infinite supply from nature, Hypocrella bambusae is used as the precursor for the preparation of CDs in this study. The obtained Hypocrella bambusae CDs (HBCDs) possess good water solubility, broad absorption (350-800 nm), red-light emission (maximum peak at 610 nm), and low biotoxicity. Moreover, HBCDs can highly generate 1O2 (0.38) and heat (27.6%) under 635 nm laser irradiation. These excellent properties of HBCDs capacitate them to be utilized for bimodal fluorescence/photoacoustic imaging-guided synergistic photodynamic therapy (PDT)/photothermal therapy (PTT). This work provides a new candidate for tumor treatment with the combination of PDT and PTT, and explores a novel approach for the preparation of CD-based phototheranostic agents with natural biomass as raw carbon sources.

Abstract
White blood cells (WBCs) are a major component of immunity in response to pathogen invasion. Neutrophils are the most abundant WBCs in humans, playing a central role in acute inflammation induced by pathogens. Adhesion to vasculature and tissue infiltration of neutrophils are key processes in acute inflammation. Many inflammatory/autoimmune disorders and cancer therapies have been found to be involved in activation and tissue infiltration of neutrophils. A promising strategy to develop novel targeted drug delivery systems is the targeting and exploitation of activated neutrophils. Herein, a new drug delivery platform based on neutrophils is reviewed. There are two types of drug delivery systems: neutrophils as carriers and neutrophil-membrane-derived nanovesicles. It is discussed how nanoparticles hijack neutrophils in vivo to deliver therapeutics across blood vessel barriers and how neutrophil-membrane-derived nanovesicles target inflamed vasculature. Finally, the potential applications of neutrophil-based drug delivery systems in treating inflammation and cancers are presented.

Abstract
The use of visible light to produce reactive oxygen species (ROS) from renewable water splitting is a highly promising means in photodynamic therapy (PDT). Up to date, diverse inorganic-organic hybrid materials developed as photosensitizers still undergo low therapeutic efficiency and/or poor stability. Herein, a kind of carbon-nanodot-decorated TiO2 nanotubes (CDots/TiO2 NTs) composite is developed and applied for photodynamic therapy. Upon 650 nm laser light excitation, the emissions with short wavelengths (325-425 nm) from the CDots as a result of upconversion process excite TiO2 NTs to form electron/hole (e- /h+ ) pairs, triggering the reaction with the adsorbed oxidants to produce ROS. Moreover, the CDots deposited on the surface of TiO2 NTs markedly enhance the light absorption response and narrow the band gap compared with anatase TiO2 nanoparticles, thereby increasing the photosensitizing efficiency. Besides, the CDots show high chemical catalytic activity for H2 O2 decomposition even if no light is needed, which is essential for PDT. The excellent therapeutic performance actuated by 650 nm light is demonstrated by in vitro and in vivo assays. This photosensitizer comprises low-cost, earth-abundant, environment-friendly merits, and especially excellent stability, implying its feasible application in biomedical field.

Abstract
Bacterial infection is one of the most serious physiological conditions threatening human health. There is an increasing demand for more effective bacterial diagnosis and treatment through noninvasive theranostic approaches. Herein, a new strategy is reported to achieve in vivo metabolic labeling of bacteria through the use of MIL-100 (Fe) nanoparticles (NPs) as the nanocarrier for precise delivery of 3-azido-d-alanine (d-AzAla). After intravenous injection, MIL-100 (Fe) NPs can accumulate preferentially and degrade rapidly within the high H2 O2 inflammatory environment, releasing d-AzAla in the process. d-AzAla is selectively integrated into the cell walls of bacteria, which is confirmed by fluorescence signals from clickable DBCO-Cy5. Ultrasmall photosensitizer NPs with aggregation-induced emission characteristics are subsequently designed to react with the modified bacteria through in vivo click chemistry. Through photodynamic therapy, the amount of bacteria on the infected tissue can be significantly reduced. Overall, this study demonstrates the advantages of metal-organic-framework-assisted bacteria metabolic labeling strategy for precise bacterial detection and therapy guided by fluorescence imaging.

Abstract
We report on the synthesis, characterization, and radioluminescence quantification of several new varieties of nanoparticles with the general composition β-NaLnF4, incorporating known luminescent activator/sensitizer pairs. Using Monte Carlo modeling to complement luminescence measurements, we have calculated the radioluminescence yields and intrinsic conversion efficiencies of colloidally-dispersed nanoparticles by comparison to an organic liquid scintillator. While five of the compositions had low to modest radioluminescence yields relative to bulk materials, colloidal β-Na(Lu0.65Gd0.2Tb0.15)F4 displayed a strong output of 39 460 photons per MeV absorbed, comparable to some of the best non-hygroscopic bulk crystal scintillators and X-ray phosphors such as Gd2O2S:Tb. Measurements of β-Na(Lu0.65Gd0.2Tb0.15)F4 powder samples revealed persistent luminescence as well as stable charge trapping, warranting further investigation.

Abstract
The simple integration of chemotherapeutic drugs and photosensitizers (PSs) into the same nanocarriers only achieves a combination of chemo-photodynamic therapy but may not confer synergistic effects. The boosted intracellular release of chemotherapeutic drugs during the photodynamic therapy (PDT) process is necessary to achieve a cascade of amplified synergistic therapeutic effects of chemo-photodynamic therapy. Methods: In this study, we explored an innovative hyperbranched polyphosphate (RHPPE) containing a singlet oxygen (SO)-labile crosslinker to boost drug release during the PDT process. The photosensitizer chlorin e6 (Ce6) and doxorubicin (DOX) were simultaneously loaded into RHPPE nanoparticles (denoted as SOHNPCe6/DOX). The therapeutic efficacy of SOHNPCe6/DOX against drug-resistant cancer was evaluated in vitro and in vivo. Results: Under 660-nm light irradiation, SOHNPCe6/DOX can produce SO, which not only induces PDT against cancer but also cleaves the thioketal linkers to destroy the nanoparticles. Subsequently, boosted DOX release can be achieved, activating a chemotherapy cascade to synergistically destroy the remaining tumor cells after the initial round of PDT. Furthermore, SOHNPCe6/DOX also efficiently detected the tumor area by photoacoustic/magnetic resonance bimodal imaging. Under the guidance of bimodal imaging, the laser beam was precisely focused on the tumor areas, and subsequently, SOHNPCe6/DOX realized a cascade of amplified synergistic chemo-photodynamic therapeutic effects. High antitumor efficacy was achieved even in a drug-resistant tumor model. Conclusion: The designed SOHNPCe6/DOX with great biocompatibility is promising for use as a co-delivery carrier for combined chemo-photodynamic therapy, providing an alternative avenue to achieve a cascade of amplified synergistic effects of chemo-photodynamic therapy for cancer treatment.

Abstract
Cancer cells contain a unique set of cell surface receptors that provide potential targets for tumor theranostics. Here, we propose an efficient approach to construct G-quadruplex-based aptamers that specifically recognize cell-surface receptors and monitor them in an amplified manner. This designed aptamer combined particular sequence for the c-Met on the cell surface and poly-G-quadruplexes structures that allow a rapid and amplified fluorescent readout upon the binding of thioflavin T (ThT). The poly-G-quadruplexes also function as a carrier for photosensitizers such as TMPyP4 in that, the aptamer further trigger the production of reactive oxygen species (ROS) to commit cells to death. This unique c-Met targeting aptamer enabled simultaneous monitoring of c-Met on the cell surface with ThT and photodynamic killing of these lung cancer cells with TMPyP4. This strategy is expected to enhance the development of tumor-targeted diagnosis and drug delivery.

Abstract
Ruthenium(ii) [Ru(ii)] polypyridyl complexes have been the focus of intense investigations since work began exploring their supramolecular interactions with DNA. In recent years, there have been considerable efforts to translate this solution-based research into a biological environment with the intention of developing new classes of probes, luminescent imaging agents, therapeutics and theranostics. In only 10 years the field has expanded with diverse applications for these complexes as imaging agents and promising candidates for therapeutics. In light of these efforts this review exclusively focuses on the developments of these complexes in biological systems, both in cells and in vivo, and hopes to communicate to readers the diversity of applications within which these complexes have found use, as well as new insights gained along the way and challenges that researchers in this field still face.

Abstract
Triple-negative breast cancer (TNBC) tumors are heterogeneous, with mesenchymal-like cells at their core and fast proliferating cells on the periphery. It is desirable and beneficial to treat TNBC cells of different phenotypes with the most appropriate drugs. Here, we report a 78 nm, chlorin e6-, docetaxel-, and anti-Twist siRNA-containing polymeric nanoparticle (CDTN) with spatiotemporally specific activity when irradiated by light. Under conditions mimicking superficial tumor tissue with sufficient light input, TNBC cells are mainly killed by the photodynamic therapy (PDT) function of CDTNs. In contrast, under conditions mimicking deep tumor tissue with weak light input, PDT potentiates chemotherapy (CT) and gene therapy (GT) by facilitating the endolysosomal escape of CDTNs. Compared with free drugs, CDTNs improve the intratumoral exposure of docetaxel and anti-Twist siRNA by 2.5- and 2-fold, respectively. When combined with laser irradiation applied at the time of maximal intratumoral accumulation, the CDTNs significantly inhibit the growth of primary tumors and their lung metastasis (both >80%) by killing the peripheral cells, mainly through PDT and prohibiting the growth and metastasis of deep cells through PDT as enhanced CT and GT. On the contrary, dual-modality nanomedicine lacking CT, GT, or PDT showed fast primary tumor growth, poor metastasis control, or both, respectively. This study reveals the spatiotemporally specific mechanism of CDTNs in treating metastatic TNBC and highlights the importance of combined therapy in treating TNBC.

Abstract
Photodynamic therapy (PDT) could be highly selective and noninvasive, with low side effects as an adjuvant therapy for cancer treatment. Because excitation sources such as UV and visible lights for most of the photosensitizers do not penetrate deeply enough into biological tissues, PDT is useful only when the lesions are located within 10 mm below the skin. In addition, there is no prior example of theranostics capable of both PDT and imaging with a single deep-penetrating X-ray excitation source. Here we report a new theranostic scintillator nanoparticle (ScNP) composite in a core-shell-shell arrangement, that is, NaLuF4:Gd(35%),Eu(15%)@NaLuF4:Gd(40%)@NaLuF4:Gd(35%),Tb(15%), which is capable of being excited by a single X-ray radiation source to allow potentially deep tissue PDT and optical imaging with a low dark cytotoxicity and effective photocytotoxicity. With the X-ray excitation, the ScNPs can emit visible light at 543 nm (from Tb3+) to stimulate the loaded rose bengal (RB) photosensitizer and cause death of efficient MDA-MB-231 and MCF-7 cancer cells. The ScNPs can also emit light at 614 and 695 nm (from Eu3+) for luminescence imaging. The middle shell in the core-shell-shell ScNPs is unique to separate the Eu3+ in the core and the Tb3+ in the outer shell to prevent resonance quenching between them and to result in good PDT efficiency. Also, it was demonstrated that although the addition of a mesoporous SiO2 layer resulted in the transfer of 82.7% fluorescence resonance energy between Tb3+ and RB, the subsequent conversion of the energy from RB to generate 1O2 was hampered, although the loaded amount of the RB was almost twice that without the mSiO2 layer. A unique method to compare the wt % and mol % compositions calculated by using the morphological transmission electron microscope images and the inductively coupled plasma elemental analysis data of the core, core-shell, and core-shell-shell ScNPs is also introduced.

Abstract
Recent studies indicate that carbon dots (CDs) can efficiently generate singlet oxygen (1 O2 ) for photodynamic therapy (PDT) of cancer. However, the hypoxic tumor microenvironment and rapid consumption of oxygen in the PDT process will severely limit therapeutic effects of CDs due to the oxygen-dependent PDT. Thus, it is becoming particularly important to develop a novel CD as an in situ tumor oxygenerator for overcoming hypoxia and substantially enhancing the PDT efficacy. Herein, for the first time, magnetofluorescent Mn-CDs are successfully prepared using manganese(II) phthalocyanine as a precursor. After cooperative self-assembly with DSPE-PEG, the obtained Mn-CD assembly can be applied as a smart contrast agent for both near-infrared fluorescence (FL) (maximum peak at 745 nm) and T1 -weighted magnetic resonance (MR) (relaxivity value of 6.97 mM-1 s-1 ) imaging. More interestingly, the Mn-CD assembly can not only effectively produce 1 O2 (quantum yield of 0.40) but also highly catalyze H2 O2 to generate oxygen. These collective properties of the Mn-CD assembly enable it to be utilized as an acidic H2 O2 -driven oxygenerator to increase the oxygen concentration in hypoxic solid tumors for simultaneous bimodal FL/MR imaging and enhanced PDT. This work explores a new biomedical use of CDs and provides a versatile carbon nanomaterial candidate for multifunctional nanotheranostic applications.

Abstract
Multifunctional nano-biomaterials with the integration of diagnostic and therapeutic functions have shown great promise in improving the efficacy of cancer therapy. Herein, a new nanoplatform based on functionalized Cu3BiS3 nanoparticles (NPs) is fabricated for tumour-targeted combination phototherapy. The as-synthesized hydrophobic Cu3BiS3 NPs are modified with DSPE-PEG/DSPE-PEG-NH2, followed by the conjugation of the photosensitizer chlorin e6 (Ce6) and the target ligand folic acid (FA). The introduced Ce6 can further form a chelate complex with Gd3+. The rationally designed Cu3BiS3-PEG-(Ce6-Gd3+)-FA NPs, which have high physiological stability and good biocompatibility, can specifically target FA-receptor over-expressed tumour cells. The Cu3BiS3-PEG-(Ce6-Gd3+)-FA NPs exhibit effective dual-modal CT and MR imaging in the xenografted HeLa tumours. Importantly, excellent in vivo anti-tumour effects have been achieved by synergistic photothermal/photodynamic therapy using the multifunctional NPs. We expect that this versatile nanoplatform will play a role in exploring precise cancer diagnosis and therapy.

Abstract
Photodynamic therapy (PDT) utilizing light-induced reactive oxygen species (ROS) is a promising alternative to combat antibiotic-resistant bacteria and biofilm. However, the photosensitizer (PS)-modified surface only exhibits antibacterial properties in the presence of light. It is known that extended photoirradiation may lead to phototoxicity and tissue hypoxia, which greatly limits PDT efficiency, while ambient pathogens also have the opportunity to attach to biorelevant surfaces in medical facilities without light. Here, an antimicrobial film composed of black phosphorus nanosheets (BPSs) and poly (4-pyridonemethylstyrene) endoperoxide (PPMS-EPO) to control the storage and release of ROS reversibly is introduced. BPS, as a biocompatible PS, can produce high singlet oxygen under the irradiation of visible light of 660 nm, which can be stably stored in PPMS-EPO. The ROS can be gradually thermally released in the dark. In vitro antibacterial studies demonstrate that the PPMS-EPO/BPS film exhibits a rapid disinfection ability with antibacterial rate of 99.3% against Escherichia coli and 99.2% against Staphylococcus aureus after 10 min of irradiation. Even without light, the corresponding antibacterial rate reaches 76.5% and 69.7%, respectively. In addition, incorporating PPMS significantly improves the chemical stability of the BPS.

Abstract
The matrix metalloproteinases (MMPs) are well-known mediators that are activated in tumor progression. MMP2 is a kind of gelatinase in extracellular matrix remodeling and cancer metastasis processes. MMP2 secretion increased in many types of cancer diseases, and its abnormal expression is associated with a poor prognosis. We fabricated a nanocomposite that sensed MMP2 expression by a red and blue light change. This nanocomposite consisted of an upconversion nanoparticle (UCNP), MMP2-sensitive peptide, and CuInS2/ZnS quantum dot (CIS/ZnS QD). An UCNP is composed of NaYF4:Tm/Yb@NaYF4:Nd/Yb, which has multiple emissions at UV/blue-visible wavelengths under 808 nm laser excitation. The conjugated CIS/ZnS QD showed the red-visible fluorescence though the FRET process. The two fluorophores were connected by a MMP2-sensitive peptide to form a novel MMP2 biosensor, named UCNP@p-QD. UCNP@p-QD was highly biocompatible according to cell viability assay. The FRET-based biosensor was employed in the MMP2 determination in vitro and in vivo. Furthermore, it was administrated into the tumor-bearing mouse to check MMP2 expression. UCNP@p-QD could be a promising tool for biological study and biomedical application. In this study, we demonstrated that the CIS/ZnS QD improved the upconversion intensity through a near-infrared-induced FRET process. This nanocomposite has the advantage of light penetration, excellent biocompatibility, and high sensitivity to sense MMP2. The near-infrared-induced composites are a potential inspiration for use in biomedical applications.

Abstract
Nanomedicine-based combination therapy has sparked a growing interest in clinical disease treatment and pharmaceutical industry. In this study, a mitochondria-targeted and near-infrared (NIR) light-activable multitasking nanographene (i.e., GT/IR820/DP-CpG) was engineered to in situ trigger highly efficient "triple-punch" strategy of cancer photodynamic therapy, photothermal therapy, and immunotherapy. Modification of triphenylphosphonium on graphene made the vehicle specifically guide the NIR dye IR820 home to mitochondria, followed by lysosomes escape in a time-dependent manner. The photoactive nanocomplex generated an abundant reactive oxygen species as well as photothermal heat to ultimately kill cancer cells by inducing mitochondrial collapse and irreversible cell apoptosis upon the NIR laser irradiation. Further introduction of an immunostimulatory conjugate DP-CpG significantly promoted the secretion of proinflammatory cytokines (i.e., interleukin-6, tumor necrosis factor-α, and interferon-γ) and thus improved the immunogenicity of tumors. In vivo studies demonstrated that GT/IR820/DP-CpG remarkably inhibited tumor growth (tumor inhibition rate, ∼88%) resulting from the combinational phototherapeutic effect of IR820 and immunostimulatory activity of DP-CpG, thereby causing negligible toxic effects on mice. Our work provides a new paradigm of architecting organelle-targeted and stimulative nanocomplex for highly efficient cancer photoimmunotherapy.

Abstract
Reactive oxygen species generation efficiency of photosensitizers and hypoxia microenvironment in solid tumor hamper photodynamic therapy (PDT) efficacy. Here, we introduce an efficient inorganic photosensitizer by incorporating plasmonic gold metal nanostructures into Cu2O semiconductors for PDT. By utilizing the plasmon-induced resonance energy transfer (PIRET) process from Au to Cu2O, Au@SiO2@Cu2O (ASC) demonstrates a high singlet oxygen quantum yield of 0.71 under a 670 nm laser irradiation. The ASC is loaded into oxygen self-enriched perfluorohexane (PFH) droplets and coated with liposome (Lip) to form Lip(ASC/PFH) nanocomposites. The achieved Lip(ASC/PFH) shows considerable anticancer efficacy for in vitro cancer cells and in vivo tumor growth. The proposed oxygen self-enriched PIRET-PDT concept has significant implication in PDT design.

Abstract
5,7-Diaryl-substituted symmetrical diazepinoporphyrazine and tribenzodiazepinoporphyrazine were synthesized and characterized using UV-Vis, MS MALDI, and various NMR techniques. The expected photosensitizing potentials of these porphyrazines were evaluated by measuring their abilities to generate singlet oxygen in organic solvents and by comparing them with that of the recently obtained dendrimeric G1-type diazepinoporhyrazine. Absorbance and fluorescence measurements were performed to study the aggregation properties of the novel macrocycles. The photocytotoxicity of tribenzodiazepinoporphyrazine towards LNCaP cells in its free form and after its incorporation into liposomes was examined using MTT assay under normoxic and hypoxic conditions. It is interesting that all tested liposome formulations maintained their phototoxic activity in hypoxia. Also, tribenzodiazepinoporphyrazine incorporated into liposomes revealed better photocytotoxic effect (IC50 values of 0.600 ± 0.357 μM and 0.378 ± 0.002 μM) than its free form (IC50 values of 3.135 ± 0.156 μM). Following the in vitro experiments, the most promising liposomal formulation containing l-α-phosphatidyl-DL-glycerol for tribenzodiazepinoporphyrazine was found. Moreover, tribenzodiazepinoporphyrazine incorporated into liposomes containing 1,2-dioleoyl-3-trimethylammonium-propane (chloride salt) revealed moderate phototoxicity at 5 × 10-5 μM for antibacterial photodynamic therapy. It was established that an irradiation of planktonic bacterial strains significantly reduced CFUs of Staphylococcus aureus ATCC 25923 in comparison to tribenzodiazepinoporphyrazine containing l-α-phosphatidyl-DL-glycerol liposomes.

Abstract
The classical photodynamic therapy (PDT) requires external light to activate photosensitizers for cancer treatment. However, limited tissue penetration of light has been a long-standing challenge for PDT to cure malignant tumors in deep tissues. Recently, Cerenkov radiation (CR) emitted by radiotracers such as 18F-fluorodeoxyglucose (18F-FDG) has become an alternative and promising internal light source. Nevertheless, fluorine-18 (F-18) only releases 1.3 photons per decay in average; consequently, injection dose of F-18 goes beyond 10-30 times more than usual to acquire therapeutic efficacy because of its low Cerenkov productivity. Gallium-68 (Ga-68) is a favorable CR source owing to its ready availability from generator and 30-time higher Cerenkov productivity. Herein, we report, for the first time, the use of Ga-68 as a CR source to activate dextran-modified TiO2 nanoparticles (D-TiO2 NPs) for CR-induced PDT. Compared with 18F-FDG, 68Ga-labeled bovine serum albumin (68Ga-BSA) inhibited the growth of 4T1 cells and exhibited significantly stronger DNA damage to tumor cells. In vivo studies showed that the tumor growth was almost completely inhibited when tumor-bearing mice were treated with a combination of D-TiO2 NPs and 68Ga-BSA. This study proved that Ga-68 is a more potent radionuclide for PDT than F-18 both in vitro and in vivo offered a promising strategy of using a diagnostic dose of radioactivity to achieve depth-independent cancer therapy without using any external light source.

Abstract
This work presents the mechanism of the photoinduced generation of reactive oxygen species (ROS) by paramagnetic copper porphyrins in aqueous solution. Electronic structure calculations within the framework of the (time-dependent) density functional theory, (TD)DFT, reveal the details regarding the development of the atomistic and electronic structures of the copper porphyrin in solution along the set of chemical reactions accessible upon photoactivation. This study identifies the key parameters controlling the feasibility of the various reaction pathways that drive the formation of specific reactive oxygen species, ROS, i.e. superoxide, peroxyl and hydroxyl radicals. An important outcome of our results is the rationalization of how the water solvent molecules play a crucial role in most steps of the overall reaction. The present study is illustrated by focusing on one specific copper porphyrin for which precise experimental data have recently been measured, and can readily be generalized to the whole family of paramagnetic porphyrins. The conclusions of this work shed light on the rational design of metalloporphyrins as photosensitizers for photodynamic therapy.

Abstract
Engineering functional nanomaterials with high therapeutic efficacy and minimum side effects has increasingly become a promising strategy for cancer treatment. Herein, a reactive oxygen species (ROS) enhanced combination chemotherapy platform is designed via a biocompatible metal-polyphenol networks self-assembly process by encapsulating doxorubicin (DOX) and platinum prodrugs in nanoparticles. Both DOX and platinum drugs can activate nicotinamide adenine dinucleotide phosphate oxidases, generating superoxide radicals (O2•- ). The superoxide dismutase-like activity of polyphenols can catalyze H2 O2 generation from O2•- . Finally, the highly toxic HO• free radicals are generated by a Fenton reaction. The ROS HO• can synergize the chemotherapy by a cascade of bioreactions. Positron emission tomography imaging of 89 Zr-labeled as-prepared DOX@Pt prodrug Fe3+ nanoparticles (DPPF NPs) shows prolonged blood circulation and high tumor accumulation. Furthermore, the DPPF NPs can effectively inhibit tumor growth and reduce the side effects of anticancer drugs. This study establishes a novel ROS promoted synergistic nanomedicine platform for cancer therapy.

Abstract
Supramolecular chemistry provides a "bottom-up" method to fabricate nanostructures for biomedical applications. Herein, we report a facile strategy to directly assemble a phthalocyanine photosensitizer (PcS) with an anticancer drug mitoxantrone (MA) to form uniform nanostructures (PcS-MA), which not only display nanoscale optical properties but also have the capability of undergoing nucleic-acid-responsive disassembly. These supramolecular assemblies possess activatable fluorescence emission and singlet oxygen generation associated with the formation of free PcS, mild photothermal heating, and a concomitant chemotherapeutic effect associated with the formation of free MA. In vivo evaluations indicate that PcS-MA nanostructures have a high level of accumulation in tumor tissues, are capable of being used for cancer imaging, and have significantly improved anticancer effect compared to that of PcS. This study demonstrates an attractive strategy for overcoming the limitations of photodynamic cancer therapy.

Abstract
This study applies in situ production of hypochlorous acid (HOCl) to improve the therapeutic efficacy of platinum drugs. The phagocytic enzyme myeloperoxidase (MPO) is coated with two functional polyphenol derivatives (platinum prodrug polyphenols and PEG polyphenols) and ferric ion by metal phenolic coordination, which can shield MPO from degradation by other compounds in the blood. Moreover, the platinum prodrug can be reduced to cisplatin in cells and produce hydrogen peroxide (H2O2). The MPO catalyzes the conversion of H2O2 to HOCl in the intercellular environment. The as-prepared MPO Pt PEG nanoparticles (MPP NPs) can be employed as a reactive oxygen species cascade bioreaction to enhance platinum drug therapy. The MPP NPs show prolonged blood circulation and high tumor accumulation as evidenced by 89Zr-based positron emission tomography imaging. The MPP NPs effectively inhibit tumor growth in vivo. As a first-in-class platform to harness the highly toxic HOCl in nanomedicine for cancer therapy, this strategy may open doors for further development of progressive therapeutic systems.

Abstract
Photodynamic therapy (PDT) is an emerging effective treatment for cancer. However, the great promise of PDT for bladder cancer therapy has not yet been realized because of tumor hypoxia. To address this challenge, we fabricated O2-generating HSA-MnO2-Ce6 NPs (HSA for human serum albumin, Ce6 for chlorin e6, and NPs for nanoparticles) to overcome tumor hypoxia and thus enhance the photodynamic effect for bladder cancer therapy. Methods: The HSA-MnO2-Ce6 NPs were prepared. We investigated the O2 generation of NPs in vitro and in vivo. The orthotopic bladder cancer model in C57BL/6 mice was established for in vivo study, and dual-modal imaging of NPs were demonstrated. Therapeutic efficacy of NPs for bladder cancer was evaluated. Results: HSA-MnO2-Ce6 NPs had an excellent performance in generating O2in vitro upon reaction with H2O2 at endogenous levels. Moreover, 1O2 generation was increased two-fold by using HSA-MnO2-Ce6 NPs instead of HSA-Ce6 NPs in the presence of H2O2 under 660 nm laser irradiation. In vitro cell viability assays showed that HSA-MnO2-Ce6 NPs themselves were non-toxic but greatly enhanced PDT effects on bladder cancer cells under laser irradiation. In vivo near-infrared (NIR) fluorescence and magnetic resonance (MR) imaging suggested the excellent bladder tumor-targeting property of HSA-MnO2-Ce6 NPs. O2 content in orthotopic bladder cancer was increased 3.5-fold after injection of HSA-MnO2-Ce6 NPs as compared with pre-injection. Given the excellent tumor-targeting ability and negligible toxicity, HSA-MnO2-Ce6 NPs were then used to treat orthotopic bladder cancer by PDT. The PDT with HSA-MnO2-Ce6 NPs showed remarkably improved therapeutic efficacy and significantly prolonged lifetime of mice as compared with controls. Conclusion: This study not only demonstrated the great potential of HSA-MnO2-Ce6 NPs for bladder cancer photodynamic ablation but also provided a new therapeutic strategy to overcoming tumor hypoxia.

Abstract
Silver nanoparticles (AgNPs) enwrapped in the biologically safe tannic acid (TA)/Fe3+ nanofilm are synthesized by an ultrafast, green, simple, and universal method. The physical antibacterial activity and photodynamic antibacterial therapy (PAT) efficacy of the TA/Fe3+/AgNPs nanofilm were investigated for the first time, which exhibited a strong physical antibacterial activity as well as great biocompatibility, through in vitro and in vivo studies. The results disclosed that this hybrid coating could possess high PAT capabilities upon irradiation under a visible light of 660 nm, which is longer than those of previously reported green and blue sensitization light, thus allowing deeper light penetration into biological tissues. Electron spin resonance (ESR) spectra proved that the PAT efficacy of the TA/Fe3+/AgNPs nanofilm was associated with the yields of singlet oxygen (1O2) under the irradiation of visible light (660 nm). A higher PAT efficiency of 100 and 94% against Escherichia coli and Staphylococcus aureus could be achieved within 20 min of illumination under 660 nm visible light, whereas the innate physical antibacterial activity of AgNPs could endow the implants with long-term prevention of bacterial infection. The mechanism of PAT may be associated with the formation of oxidative stress and oxidative damage to key biomolecules (proteins and lipids) in bacteria. Our results reveal that the synergistic action of both PAT and physical action of AgNPs in this hybrid nanofilm is an effective way to inactivate bacteria, with minimal side effects.

Abstract
TiO2 nanoparticles modified with phthalocyanines (Pc) have been proven to be a potential photosensitizer in the application of photodynamic therapy (PDT). However, the generation of reactive oxygen species (ROS) by TiO2 nanoparticles modified with Pc has not been demonstrated clearly. In this study, nitrogen-doped TiO2 conjugated with Pc (N-TiO2-Pc) were studied by means of monitoring the generation of ROS. The absorbance and photokilling effect on HeLa cells upon visible light of different regions were also studied and compared with non-doped TiO2-Pc and Pc. Both N-TiO2-Pc and TiO2-Pc can be activated by visible light and exhibited much higher photokilling effect on HeLa cells than Pc. In addition, nitrogen-doping can greatly enhance the formation of 1O2 and •O2−, while it suppresses the generation of OH•. This resulted in significant photodynamic activity. Therefore, N-TiO2-Pc can be an excellent candidate for a photosensitizer in PDT with wide-spectrum visible irradiation.

Abstract
Cancer is rapidly becoming the top killer in the world. Most of the FDA approved anticancer drugs are organic molecules, while metallodrugs are very scarce. The advent of the first metal based therapeutic agent, cisplatin, launched a new era in the application of transition metal complexes for therapeutic design. Due to their unique and versatile biochemical properties, ruthenium-based compounds have emerged as promising anti-cancer agents that serve as alternatives to cisplatin and its derivertives. Ruthenium(iii) complexes have successfully been used in clinical research and their mechanisms of anticancer action have been reported in large volumes over the past few decades. Ruthenium(ii) complexes have also attracted significant attention as anticancer candidates; however, only a few of them have been reported comprehensively. In this review, we discuss the development of ruthenium(ii) complexes as anticancer candidates and biocatalysts, including arene ruthenium complexes, polypyridyl ruthenium complexes, and ruthenium nanomaterial complexes. This review focuses on the likely mechanisms of action of ruthenium(ii)-based anticancer drugs and the relationship between their chemical structures and biological properties. This review also highlights the catalytic activity and the photoinduced activation of ruthenium(ii) complexes, their targeted delivery, and their activity in nanomaterial systems.

Abstract
Photodynamic therapy (PDT), which relies on photosensitizers (PS) and light to generate reactive oxygen species to kill cancer cells or bacteria, has attracted much attention in recent years. PSs with both bright emission and efficient singlet oxygen generation have also been used for image-guided PDT. However, simultaneously achieving effective 1 O2 generation, long wavelength absorption, and stable near-infrared (NIR) emission with low dark toxicity in a single PS remains challenging. In addition, it is well known that when traditional PSs are made into nanoparticles, they encounter quenched fluorescence and reduced 1 O2 production. In this contribution, these challenging issues have been successfully addressed through designing the first photostable photosensitizer with aggregation-induced NIR emission and very effective 1 O2 generation in aggregate state. The yielded nanoparticles show very effective 1 O2 generation, bright NIR fluorescence centered at 820 nm, excellent photostability, good biocompatibility, and negligible dark in vivo toxicity. Both in vitro and in vivo experiments prove that the nanoparticles are excellent candidates for image-guided photodynamic anticancer therapy.

Abstract
Near infrared (NIR) light triggered phototherapy including photothermal therapy (PTT) and photodynamic therapy (PDT) affords superior outcome in cancer treatment. However, the reactive oxygen species (ROS) generated by NIR-excited upconversion nanostructure is limited by the feeble upconverted light which cannot activate PDT agents efficiently. Here, an IR-808 dye sensitized upconversion nanoparticle (UCNP) with a chlorin e6 (Ce6)-functionalized silica layer is developed for PDT agent. The two booster effectors (dye-sensitization and core-shell enhancement) synergistically amplify the upconversion efficiency, therefore achieving superbright visible emission under low 808 nm light excitation. The markedly amplified red light subsequently triggers the photosensitizer (Ce6) to produce large amount of ROS for efficient PDT. After the silica is endowed with positive surface, these PDT nanoparticles can be easily grafted on MoS2 nanosheet. As the optimal laser wavelength of UCNPs is consistent with that of MoS2 nanosheet for PTT, the invented nanoplatform generates both abundant ROS and local hyperthermia upon a single 808 nm laser irradiation. Both the in vitro and in vivo assays validate that the innovated nanostructure presents excellent cancer cell inhibition effectiveness by taking advantages of the synergistic PTT and PDT, simultaneously, posing trimodal (upconversion luminescence/computed tomography (CT)/magnetic resonance imaging (MRI) imaging capability.

Abstract
Photodynamic therapy (PDT), which relies on photosensitizers (PS) and light to generate reactive oxygen species to kill cancer cells or bacteria, has attracted much attention in recent years. PSs with both bright emission and efficient singlet oxygen generation have also been used for image-guided PDT. However, simultaneously achieving effective 1 O2 generation, long wavelength absorption, and stable near-infrared (NIR) emission with low dark toxicity in a single PS remains challenging. In addition, it is well known that when traditional PSs are made into nanoparticles, they encounter quenched fluorescence and reduced 1 O2 production. In this contribution, these challenging issues have been successfully addressed through designing the first photostable photosensitizer with aggregation-induced NIR emission and very effective 1 O2 generation in aggregate state. The yielded nanoparticles show very effective 1 O2 generation, bright NIR fluorescence centered at 820 nm, excellent photostability, good biocompatibility, and negligible dark in vivo toxicity. Both in vitro and in vivo experiments prove that the nanoparticles are excellent candidates for image-guided photodynamic anticancer therapy.
