Abstract
Nowadays, the selective release of therapeutic drugs into tumor cells has become an important way of tumor treatment due to the high side effects of chemotherapy drugs. As one of the gas mediators, hydrogen sulfide (H2S) is closely related to cancer. Due to the high content of H2S in tumor cells, it can be used as a signaling molecule that triggers the release of drugs to achieve the selective release of therapeutic drugs. In addition, dual-channel fluorescence imaging technology can be better applied to monitor the drug delivery process and distinguish the state before and after drug release, so as to better track the effect of drug therapy. Based on this, we used NBD amines (NBD-NHR) as the recognition group of H2S and connected the tyrosine kinase inhibitor crizotinib to construct an activated dual-channel fluorescent probe CZ-NBD. After the probe enters the tumor cells, it consumes H2S and releases crizotinib, which is highly toxic to the tumor cells. Importantly, the probe displays significant fluorescence changes in different cells, enabling not only the screening of tumor cells, but also tracking and monitoring drug release and tumor cell activity. Therefore, the construction of probe CZ-NBD provides a new strategy for drug release monitoring in tumor cells.

Abstract
Amphiphilic copolymers have long been utilized to turn hydrophobic anticancer drugs into nanoparticles administered to patients with cancer. A lack of stability in these monotherapies may be blamed for their poor clinical results in patients with cancer. We propose novel nanotherapies based on polymeric small prodrugs that preserve pharmacologic effectiveness while significantly reducing the toxicity of the fabricated drugs in animals to overcome this problem. Doxorubicin is attached to the end of the PLA fragments through a hydrolyzable ester bond utilizing methoxypolyethylene glycol-block-poly(d, l-lactic acid) (mPEG-PCL(2K)) with conjugates to mimic the self-assembly of colloidal nanotherapies. In a gastric cancer xenograft model, this nanotherapy displays a long-lasting suppression of tumor growth once a reasonable dosage is administered. Our findings imply that a toxic chemical and hydrophobic can be converted into therapeutic effective self-delivery nanotreatment.

Abstract
Nanomedicine has developed as a potential technique for successful cancer therapy. A simple supramolecular self-assembly process is a helpful strategy for generating carrier-free nanodrugs. Mixing photodynamic treatment with chemotherapy has been sought to obtain a high therapeutic impact. In this study, we effectively construct a nanocarrier (CD-Por-PEG: Ada-CPT-Pt(IV)) combined with Carboplatin prodrug (Ada-CPT-Pt(IV)) and photosensitizer porphyrin (CD-Por-PEG) by host-guest interactions to accomplish stimuli-response combination treatment. Supported by greater spatial control of the binding ratio among host-guest molecules, Carboplatin and porphyrin were independently altered with β-cyclodextrin and adamantane to produce the amphiphilic host-guest combination for sequential self-assembly into therapeutic nanoparticles. The colloidal stability of the produced CD-Por-PEG: Ada-CPT-Pt(IV)-NPs was excellent, with an average hydrodynamic diameter of ∼170 nm. The microscopy images showed that CD-Por-PEG: Ada-CPT-Pt(IV) could aggregate cells and generate ROS after light irradiation (630 nm). Monotherapy had a cytotoxicity three times greater than the CD-Por-PEG: Ada-CPT-Pt(IV) nanoparticles. Studies in mice carrying SUNE1 nasopharyngeal tumours showed that nanoparticles effectively suppressed tumour development without causing systemic damage in this examination. The current self-assembly nanosystem makes precise control over the photosensitizer and drug loading possible ratio. It reduces the systemic adverse toxicity issues of drugs carrier, making this system ideal for nasopharyngeal cancer treatment.

Abstract
Monitoring intracellular administration of non-luminescent anticancer drugs like cisplatin is a very challenging task in cancer research. Perylenebisimide (PBI) chromophore tagged fluorescent ABC-triblock polycaprolactone (PCL) nanoscaffold was engineered having carboxylic acid blocks for the chemical conjugation of cisplatin at the core and hydrophilic PEG blocks at the periphery. The amphiphilic ABC triblock Pt-prodrug was self-assembled into < 200 nm nanoparticles and exhibited excellent shielding against drug detoxification by the glutathione (GSH) species in the cytosol. In vitro drug release studies confirmed that the Pt-prodrug was stable at extracellular conditions and the PCL block exclusively underwent lysosomal-enzymatic biodegradation at the intracellular level to release the cisplatin drug in the active-form for accomplishing more than 90% cell growth inhibition. Confocal microscopic imaging of the red-fluorescence signals from the perylene chromophores established the simultaneous monitoring and delivery aspects of Pt-prodrug, and the proof-of-concept was successfully demonstrated in breast and cervical cancer cell lines.

Abstract
Combination therapy in cancer therapy has been widely used for its positive attributes, such as minimizing the undesirable side effects of chemotherapies and enhancing the therapeutic effects on different cancers. Compared with free drugs crizotinib (CRZ) and gemcitabine (GEM), CRZ@GEM-NPs could remarkably improve the cytotoxicity for endometrial cancer (EC) cells (Ishikawa cells and KLE cells) after treatment with MTT assay. In this study, CRZ and GEM were conjugated to tri-block copolymer poly(ε-caprolactone)-poly(ethylene glycol)-poly(ε-caprolactone) (PCL-PEG-PCL, known as NPs). The fabricated nanoparticles were characterized by the high-resolution transmission electron microscopy (HR-TEM), and the particles size and zeta potential were investigated by the dynamic light scattering analysis. Further, the morphological features of the EC cell lines were examined by the biochemical staining assays. Morphological changes in endometrial cells morphology revealed by nuclear fragmentation and nuclear condensation (the hallmarks of apoptosis) were noted upon treatment with CRZ@GEM-NPs to the Ishikawa and KLE cancer cells. In addition, resulting in the highest ratio of apoptosis and mitochondrial membrane potential shows the cell death through the mitochondrial membrane potential. In vivo, systemic toxicity studies showed no histological changes and substantial blood biochemical with the near-normal appearance of the organs upon treatment with CRZ@GEM-NPs. Overall, the targeted combination suitable therapeutic framework may be a promising candidate for improved EC therapy.

Abstract
This study was focused on synthesizing, characterizing and evaluating the biological potential of Polyelectrolyte Complex Nanoparticles (PECNs) loaded with the antibiotic ampicillin. For this, the PECNs were produced initially by polyelectrolytic complexation (bottom-up method) and subsequently subjected to ultra-high pressure homogenization-UHPH (top-down method). The synthetic polymeric materials corresponding to the sodium salt of poly(maleic acid-alt-octadecene) (PAM-18Na) and the chloride salt of Eudragit E-100 (EuCl) were used, where the order of polyelectrolyte complexation, the polyelectrolyte ratio and the UHPH conditions on the PECNs features were evaluated. Likewise, PECNs were physicochemically characterized through particle size, polydispersity index, zeta potential, pH and encapsulation efficiency, whereas the antimicrobial effect was evaluated by means of the broth microdilution method employing ampicillin sensitive and resistant S. aureus strains. The results showed that the classical method of polyelectrolyte complexation (bottom-up) led to obtain polymeric complexes with large particle size and high polydispersity, where the 1:1 ratio between the titrant and receptor polyelectrolyte was the most critical condition. In contrast, the UHPH technique (top-down method) proved high performance to produce uniform polymeric complexes on the nanometric scale (particle size < 200 nm and PDI < 0.3). Finally, it was found there was a moderate increase in antimicrobial activity when ampicillin was loaded into the PECNs.

Abstract
Cisplatin cis-(diammine)dichloridoplatinum(II) (CDDP) is the first platinum-based complex approved by the food and drug administration (FDA) of the United States (US). Cisplatin is the first line chemotherapeutic agent used alone or combined with radiations or other anti-cancer agents for a broad range of cancers such as lung, head and neck. Aroplatin™, Lipoplatin™ and SPI-077 are PEGylated liposome-based nano-formulations that are still under clinical trials. They have many limitations, for example, poor aqueous solubility, drug resistance and toxicities, which can be overcome by encapsulating the cisplatin in Nemours nanocarriers. The extensive literature from different electronic databases covers the different nano-delivery systems that are developed for cisplatin. This review critically emphasizes on the recent advancement, development, innovations and updated literature reported for different carrier systems for CDDP.

Abstract
Carriers that can afford tunable physical and structural changes are envisioned to address critical issues in controlled drug delivery applications. Herein, photo-responsive conjugated polymer nanoparticles (CPNs) functionalized with donor-acceptor Stenhouse adduct (DASA) and folic acid units for controlled drug delivery and imaging are reported. Upon visible-light (λ=550 nm) irradiation, CPNs simultaneously undergo structure, color, and polarity changes that release encapsulated drugs into the cells. The backbone of CPNs favors FRET to DASA units boosting their fluorescence. Notably, drug-loaded CPNs exhibit excellent biocompatibility in the dark, indicating perfect control of the light trigger over drug release. Delivery of both hydrophilic and hydrophobic drugs with good loading efficiency was demonstrated. This strategy enables remotely controlled drug delivery with visible-light irradiation, which sets an example for designing delivery vehicles for non-invasive therapeutics.

Abstract
Cisplatin (CDDP) has been considered as one of the most effective anticancer drugs against cervical cancer, but the lack of selectivity of CDDP to tumor tissues often leads to serious toxic side effects. In this study, CDDP-incorporated Cy5.5-PEG- g-A-HA nanoparticles were prepared to endue CDDP the ability to selectively target tumors and fluorescence imaging in vivo. The nanoparticles exhibited a spherical shape with particle sizes between 216.4 and 281.5 nm and had a pH and Cl- concentration dependence on controlled and sustained CDDP release, which was favorable for nanoparticles to release more drugs at acidic tumor microenvironment. Cell biology experiments demonstrated that the nanoparticles had good biocompatibility and tumor targeting; the nanoparticles could selectively bind and internalize into HeLa cells and induce apoptosis, but lead to less cytotoxicity on NIH3T3 cells. What is more, the nanoparticles could be clearly fluorescent-imaged in vivo and showed an effective accumulation at the tumor site. Antitumor test in vivo displayed that the nanoparticles had good antitumor efficiency and low systemic toxicity which improved the life quality of mice. Hence, the CDDP-incorporated Cy5.5-PEG- g-A-HA nanoparticles were a potential delivery system for targeting delivery of CDDP against cervical cancer.

Abstract
In this study, for the first time, CuFeS2 nanocrystals were successfully prepared through a facile noninjection-based synthetic strategy, by reacting Cu and Fe precursors with dodecanethiol in a 1-octadecene solvent. This one-pot noninjection strategy features easy handling, large-scale production, and high synthetic reproducibility. Following hyaluronic acid (HA) encapsulation, CuFeS2 nanocrystals coated with HA (CuFeS2@HA) not only readily dispersed in water and showed improved biocompatibility but also possessed a tumor-specific targeting ability of cancer cells bearing the cluster determinant 44 (CD44) receptors. The encapsulated CuFeS2@HA showed broad optical absorbance from the visible to the near-infrared (NIR) region and high photothermal conversion efficiencies of about 74.2%. They can, therefore, be utilized for the photothermal ablation of cancer cells with NIR light irradiation. In addition, toxicity studies in vitro (B16F1 and HeLa) and in vivo (zebrafish embryos), as well as in vitro blood compatibility studies, indicated that CuFeS2@HA show low cytotoxicity at the doses required for photothermal therapy. More importantly, CuFeS2@HA can be used as delivery vehicles for chemotherapy cisplatin(IV) prodrug forming CuFeS2@HA-Pt(IV). Their release profile revealed pH- and glutathione-mediated drug release from CuFeS2@HA-Pt(IV), which may minimize the side effects of the drug to normal tissues during therapy. Subsequent in vitro experiments confirmed that the use of CuFeS2@HA-Pt(IV) provides an enhanced and synergistic therapeutic effect compared to that from the use of either chemotherapy or photothermal therapy alone.

Abstract
The development of near-infrared (NIR) fluorescent probes is critical for in vivo exploration of the fundamental and complex processes in living systems by noninvasive fluorescence imaging techniques. Semiconducting polymer dots (Pdots) are emerging as important probes that exhibit several advantages, such as high brightness and biocompatibility. However, NIR-emitting Pdots are very rare, particularly at the center (∼800 nm) of the first optical window of biological tissues (between 650 nm and 950 nm). In this paper, we describe the synthesis of a semiconducting polymer with bright and narrow-band emission at 800 nm. The polymer was designed by incorporating a NIR porphyrin unit into a conjugated backbone; the polymer used a cascade energy transfer to produce the signal. The resulting Pdots possessed a narrow emission bandwidth (FWHM ∼ 23 nm) and good fluorescence quantum yield (QY = 8%), which is high for a near-IR emitter. The Pdots were bioconjugated with streptavidin for specific labeling of cellular targets, yielding higher staining index when compared with commercial NIR probes, such as PE-Cy7. Moreover, the NIR polymer was combined with a long-wavelength absorbing polymer to make bright Pdots (QY = 15%) for in vivo noninvasive imaging. These NIR Pdots with surface PEGylation led to high-contrast imaging of lymph nodes and tumors in a mouse model. This work highlights the great potential of the NIR Pdots for cellular and in vivo imaging applications.

Abstract
This article reports an effective method to regulate hydrophobic drug release rate from partially silica-coated bicellar nanodisc generated from proamphiphilic organoalkoxysilane and dihexanoylphosphatidylcholine by introducing different molar percentages of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-PEG2000 (DSPE-PEG2000) into planar bilayers of hybrid bicelles. It was found that the drug release rate increased with increasing the molar percentages of DSPE-PEG2000, and 57.38%, 69.21%, 78.69%, 81.64%, and 82.23% of hydrophobic doxorubicin was released within 120 h from the nanodics incorporating with 0%, 2.5%, 5%, 10%, and 20% DSPE-PEG2000, respectively. Compared with the non-PEGylated nanodisc and free doxorubicin, the PEGylated nanodiscs showed good biocompatibility, high cellular uptake, and adhesion, as well as high local drug accumulation. In addition, both in vitro and in vivo results demonstrated significantly improved antitumor efficacy of the PEGylated nanodisc than its control groups. Thus, the PEGylated nanodisc with partial silica coating offers a facile and efficient strategy of drug delivery for chemotherapy with improved patient acceptance and compliance.

Abstract
As an emerging class of optical nanomaterials, semiconducting polymer nanoparticles (SPNs) are highly photostable, optically active and versatile in chemistry; these properties make them attractive as molecular imaging agents to enable imaging of biological events and functionalities at multiple scales. More recently, a variety of SPNs have been found to exhibit high photoacoustic properties, and further empowered photoacoustic imaging for contrast enhanced in vivo molecular imaging. Target-sensitive components can be incorporated in the SPNs to create activatable imaging probes to sense and monitor the target dynamics in living objects. Intrinsically biophotonic and biocompatible, SPNs can be further engineered for multimodal imaging and for real-time imaging of drug delivery.

Abstract
Dextran sulfate sodium (DS) was allowed to interact ionically with ropinirole hydrochloride (ROPI HCl, an anti-Parkinsonian agent) to synthesize self-assembled ROPI-DS nanoplex. The preliminary objective behind ROPI-DS complexation was to enhance the partitioning of ROPI HCl and thereby its encapsulation into nanocarriers and to improve the nasal membrane permeability. Molecular interactions were computed using in silico molecular modeling. Nanoplex were characterized for physicochemical and partitioning behavior. Optimized ROPI-DS nanoplex was further characterized by spectroscopic and thermal analysis, diffraction studies, morphological and histopathological analysis. In summary, ROPI-DS nanoplex represents a promising nanocarrier material for intranasal administration.

Abstract
Ample attention has focused on cancer drug delivery via prodrug nanoparticles due to their high drug loading property and comparatively lower side effects. In this study, we designed a PEG-DOX-Cur prodrug nanoparticle for simultaneous delivery of doxorubicin (DOX) and curcumin (Cur) as a combination therapy to treat cancer. DOX was conjugated to PEG by Schiff's base reaction. The obtained prodrug conjugate could self-assemble in water at pH 7.4 into nanoparticles (PEG-DOX NPs) and encapsulate Cur into the core through hydrophobic interaction (PEG-DOX-Cur NPs). When the PEG-DOX-Cur NPs are internalized by tumor cells, the Schiff's base linker between PEG and DOX would break in the acidic environment that is often observed in tumors, causing disassembling of the PEG-DOX-Cur NPs and releasing both DOX and Cur into the nuclei and cytoplasma of the tumor cells, respectively. Compared with free DOX, free Cur, free DOX-Cur combination, or PEG-DOX NPs, PEG-DOX-Cur NPs exhibited higher anti-tumor activity in vitro. In addition, the PEG-DOX-Cur NPs also showed prolonged blood circulation time, elevated local drug accumulation and increased tumor penetration. Enhanced anti-tumor activity was also observed from the PEG-DOX-Cur-treated animals, demonstrating better tumor inhibitory property of the NPs. Thus, the PEG-DOX-Cur prodrug nanoparticle system provides a simple yet efficient approach of drug delivery for chemotherapy.

Abstract
Platinum drug delivery against the detoxification of cytoplasmic thiols is urgently required for achieving efficacy in breast cancer treatment that is over expressed by glutathione (GSH, thiol-oligopeptide). GSH-resistant polymer-cisplatin core-shell nanoparticles were custom designed based on biodegradable carboxylic functional polycaprolactone (PCL)-block-poly(ethylene glycol) diblock copolymers. The core of the nanoparticle was fixed as 100 carboxylic units and the shell part was varied using various molecular weight poly(ethylene glycol) monomethyl ethers (MW of PEGs = 100-5000 g mol(-1)) as initiator in the ring-opening polymerization. The complexation of cisplatin aquo species with the diblocks produced core-shell nanoparticles of 75 nm core with precise size control the particles up to 190 nm. The core-shell nanoparticles were found to be stable in saline solution and PBS and they exhibited enhanced stability with increase in the PEG shell thickness at the periphery. The hydrophobic PCL layer on the periphery of the cisplatin core behaved as a protecting layer against the cytoplasmic thiol residues (GSH and cysteine) and exhibited <5% of drug detoxification. In vitro drug-release studies revealed that the core-shell nanoparticles were ruptured upon exposure to lysosomal enzymes like esterase at the intracellular compartments. Cytotoxicity studies were performed both in normal wild-type mouse embryonic fibroblast cells (Wt-MEFs), and breast cancer (MCF-7) and cervical cancer (HeLa) cell lines. Free cisplatin and polymer drug core-shell nanoparticles showed similar cytotoxicity effects in the HeLa cells. In MCF-7 cells, the free cisplatin drug exhibited 50% cell death whereas complete cell death (100%) was accomplished by the polymer-cisplatin core-shell nanoparticles. Confocal microscopic images confirmed that the core-shell nanoparticles were taken up by the MCF-7 and HeLa cells and they were accumulated both at the cytoplasm as well at peri-nuclear environments. The present investigation lays a new foundation for the polymer-based core-shell nanoparticles approach for overcoming detoxification in platinum drugs for the treatment of GSH over-expressed breast cancer cells.

Abstract
A series of BODIPY derivatives with tetraphenylethene (TPE) moieties were designed and synthesized. The effect of positions and numbers of substitution groups on the fluorescence of the BODIPYs was investigated. Theoretical calculation and single crystal structures proved that the TPE substitution groups on the 8-position of BODIPY contributed little to the conjugation, but benefited the aggregated state emission. On the other hand, the substitutions on the 3- or 5-position of BODIPY through vinyl bridges increased the conjugation length, and generated big coplanar π-conjugated structures with poor aggregated state emission. The compound with bright aggregated state emission has been further fabricated into biocompatible fluorescent nanoparticles and used as effective fluorescent contrast agents for intracellular imaging.

Abstract
The development of polymeric luminescent nanomaterials for biomedical applications has recently attracted a large amount of attention due to the remarkable advantages of these materials compared with small organic dyes and fluorescent inorganic nanomaterials. Among these polymeric luminescent nanomaterials, polymeric luminescent nanomaterials based on dyes with aggregation-induced emission (AIE) properties should be of great research interest due to their unique AIE properties, the designability of polymers and their multifunctional potential. In this review, the recent advances in the design and biomedical applications of polymeric luminescent nanomaterials based on AIE dyes is summarized. Various design strategies for incorporation of these AIE dyes into polymeric systems are included. The potential biomedical applications such as biological imaging, and use in biological sensors and theranostic systems of these polymeric AIE-based nanomaterials have also been highlighted. We trust this review will attract significant interest from scientists from different research fields in chemistry, materials, biology and interdisciplinary areas.

Abstract
The design and synthesis is reported for a fluorescent conjugated polymer (CP), poly{[4,4,9,9-tetrakis(4-(octyloxy)phenyl-4,9-dihydro-s-indaceno[1,2-b:5,6-b']dithiophene)]-alt-co-[4,7-di(thiophen-2-yl)-2,1,3-benzothiadiazole]} (PIDT-DBT), with absorption and emission profiles fallen within far-red/near infrared (FR/NIR) region and further demonstrate its application in long-term in vitro cell tracing and in vivo imaging of liver tumor growth. PIDT-DBT-Tat nanoparticles (NPs) have an absorption maximum at ≈600 nm with an emission maximum at ≈720 nm in water. In vitro cell tracing studies reveal that PIDT-DBT-Tat NPs can trace HepG2 liver cancer cells over 8 d. In vivo imaging results indicate that PIDT-DBT-Tat NPs can monitor liver tumor growth for more than 27 d in a real-time manner. Both in vitro and in vivo studies demonstrate that PIDT-DBT-Tat NPs are superior to commercial Qtracker 705 as fluorescent probes. This study demonstrates for the first time the feasibility for long-term in vivo imaging of tumor growth by utilizing CP-based fluorescent probes, which will encourage the development of NIR fluorescent CPs for in vivo bioimaging.
