J Colloid Interface Sci 2024; 674:791-804. [PMID: 38955010 DOI: 10.1016/j.jcis.2024.06.205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 06/22/2024] [Accepted: 06/26/2024] [Indexed: 07/04/2024]
Abstract
Selective oxidation of sulfur mustard gas (HD) to non-toxic sulfoxide by the visible-light-catalyzed generation of singlet oxygen (1O2) is a promising degradation strategy. Although PCN-224 can absorb visible light, it suffers from rapid electron-hole recombination and low redox capacity, which limits the performance of HD degradation. Titanium dioxide (TiO2) is an excellent photocatalyst but it lacks visible-light-activity in degrading HD. In this study, PCN-224@TiO2 heterojunction with S-type core-shell structure was synthesized by in-situ growth method to prolong the visible light absorption capacity of TiO2 and inhibit the rapid recombination of PCN-224. The interface formation and internal electric field were optimized by adjusting the Zr/Ti ratio to enhance the charge transfer, redox capacity, electron-hole separation, and visible light absorption. In this study, the formation of heterojunction composites based on Zr-O-Ti linkages is demonstrated by a series of characterization methods. It is demonstrated by experiments and theoretical calculations that PCN-224@TiO2 can generate nearly 100 % 1O2 under visible light conditions without a sacrificial agent, resulting in efficient and selective oxidation of 2-chloroethyl ethyl sulfide (CEES), a simulant of HD, to non-toxic sulfoxide form.

Abstract
The poor clinical performance of titanium and its alloy implants is mainly attributed to their lack of antibacterial ability and poor osseointegration. The key and challenge lie in how to enhance their osteoinductivity while imparting antibacterial capability. In this study, a titanium oxide metasurface with light-responsive behavior was constructed on the surface of titanium alloy using an alkaline-acid bidirectional hydrothermal method. The effects of the acid type, acid concentration, hydrothermal time, hydrothermal temperature, and subsequent heat treatments on the optical behavior of the metasurface were systematically investigated with a focus on exploring the influence of the metasurface and photodynamic reaction on the osteogenic activity of osteoblasts. Results show that the type of acid and heat treatment significantly affect the light absorption of the titanium alloy surface, with HCl and post-heat-treatment favoring redshift in the light absorption. Under 808 nm near-infrared (NIR) irradiation for 10 min, in vitro antibacterial experiments demonstrate that the antibacterial rate of the metasurface titanium alloy against Staphylococcus aureus and Escherichia coli were 96.87% and 99.27%, respectively. In vitro cell experiments demonstrate that the nanostructure facilitates cell adhesion, proliferation, differentiation, and expression of osteogenic-related genes. Surprisingly, the nanostructure promoted the expression of relevant osteogenic genes of MC3T3-E1 under 808 nm NIR irradiation. This study provides a method for the surface modification of titanium alloy implants.

Abstract
The greatest barrier to the further development and clinical application of tumor image-guided photodynamic therapy (PDT), is the inconsistency between the fluorescence intensity and singlet oxygen generation yield of the photosensitizer under light excitation. Herein, a novel donor-acceptor (D-A) system is designed from the point of molecular selection by wrapping a classical porphyrin molecule (5,10,15,20-tetraphenylphorphyrin, H2 TPP) as an acceptor into conjugated polymer (Poly[N,N'-bis(4-butylpheny)-N,N'-bis(phenyl)benzidine], ADS254BE) as a donor through fluorescence resonance energy transfer (FRET) mechanism, which exhibits bright red emission centered at 650 nm (quantum yield, 0.12), relatively large Stoke shift of 276 nm, enhanced singlet oxygen generation rate of 0.73, and excellent photostability. The investigations on distribution and killing effect of nanomaterials in cancer cells reveal that ADS254BE/H2 TPP NPs can accumulate in the cytoplasm for imaging while simultaneously producing a large amount of singlet oxygen to remarkably kill cancer cells, which can be used for real-time image-guided PDT. In the xenograft tumor model, real-time imaging and long-term tracing in tumor tissue with ADS254BE/H2 TPP NPs disclose that the growth of lung cancer in mice can be effectively inhibited during in situ imaging. From the standpoint of molecular engineering design, this work provides a feasible strategy for novel D-A systems to improve the development of image-guided PDT.

Abstract
Photodynamic therapy (PDT) is a clinically approved noninvasive tumor therapy that can selectively kill malignant tumor cells, with promising use in the treatment of various cancers. PDT is typically composed of three important parts: the specific wavelength of light, photosensitizer (PS), and oxygen. With the progressing investigation on PDT treatment, the most recent attention has focused on improving photodynamic efficiency. Tumor hypoxia has always been a critical factor hindering the efficacy of PDT. Nanoscale metal-organic frameworks (nMOF), the fourth generation of PS, present great potential in photodynamic therapy. In particular, nMOF combined with metal nanoparticles and metal oxide/peroxide has demonstrated unique properties for enhanced PDT. The metal and metal oxide nanoparticles can catalyze H2O2 to generate oxygen or automatically produces oxygen, alleviating the hypoxia and improving the photodynamic efficiency. Metal peroxide nanoparticles can spontaneously produce oxygen in water or under acidic conditions. Therefore, this Review summarizes the recent development of nMOF combined with metal nanoparticles (platinum nanoparticles and gold nanoparticles) and metal oxide/peroxide (manganese dioxide, ferric oxide, cerium oxide, calcium peroxide, and magnesium peroxide) for enhanced photodynamic therapy by alleviating tumor hypoxia. Finally, future perspectives of nMOF combined nanomaterials in PDT are put forward.

Abstract
OPINION STATEMENT Photodynamic therapy (PDT) has garnered increasing attention in cancer treatment because of its advantages such as minimal invasiveness and selective destruction. With the development of PDT, impressive progress has been made in the preparation of photosensitizers, particularly porphyrin photosensitizers. However, the limited tissue penetration of the activating light wavelengths and relatively low light energy capture efficiency of porphyrin photosensitizers are two major disadvantages in conventional photosensitizers. Therefore, tissue penetration needs to be enhanced and the light energy capture efficiency of porphyrin photosensitizers improved through structural modifications. The indirect excitation of porphyrin photosensitizers using fluorescent donors (fluorescence resonance energy transfer) has been successfully used to address these issues. In this review, the enhancement of the light energy capture efficiency of porphyrins is discussed.

Abstract
Photodynamic therapy and sonodynamic therapy are two highly promising modalities for cancer treatment. The latter holds an additional advantage in deep-tumor therapy owing to the deep penetration of the ultrasonic radiation. The therapeutic efficacy depends highly on the photo/ultrasound-responsive properties of the sensitizers as well as their tumor-localization property and pharmacokinetics. A novel nanosensitizer system based on a polymeric phthalocyanine (pPC-TK) is reported herein in which the phthalocyanine units are connected with cleavable thioketal linkers. Such polymer could self-assemble in water forming nanoparticles with a hydrodynamic diameter of 48 nm. The degradable and flexible thioketal linkers could effectively inhibit the π-π stacking of the phthalocyanine units, rendering the resulting nanoparticles an efficient generator of reactive oxygen species upon light or ultrasonic irradiation. The nanosensitizer could be internalized into cancer cells readily, inducing cell death by efficient photodynamic and sonodynamic effects. The potency is significantly higher than that of the monomeric phthalocyanine (PC-4COOH). The nanosensitizer could also effectively inhibit the growth of tumor in liver tumor-bearing mice by these two therapies without causing noticeable side effects. More importantly, it could also retard the growth of a deep-located orthotopic liver tumor in vivo by sonodynamic therapy.

Abstract
Aggregation caused quenching (ACQ) effect can severely inhibit the application of hydrophobic photosensitizers (PSs) bearing planar and rigid structures. Most of the reported cases utilized random-coiled polymers for the in vivo delivery of PSs, which would inevitably aggravate ACQ effect due to the flexible chains. In this work, the role of polymers' secondary structures (especially α-helical conformation) in overcoming the PSs' aggregation is systemically investigated based on the design of α-helical polypeptides bearing tetraphenylporphyrin (TPP) side chains. Atomistic molecular dynamics simulation, fluorescence quantum yield, and reactive oxygen species (ROS) generation yield are evaluated to demonstrate that α-helical polypeptide backbones can significantly boost both fluorescence quantum yield and ROS by suppressing the π-π stacking interaction between TPP units. The enhanced in vitro and in vivo phototoxicity for helical polypeptides also reveal functions of secondary structures in inhibiting ACQ and improving the membrane activity. Successful in vivo photodynamic therapy (PDT) results in mice bearing H22 tumors showed great potentials for further clinical applications.

Herein, we have summarized the representative research advances of biodegradable nanomaterials with respect to the mechanism of degradation and their application in tumor imaging and therapy. First, four kinds of tumor microenvironment (TME) responsive degradation are presented, including pH, glutathione (GSH), hypoxia and matrix metalloproteinase (MMP) responsive degradation. Second, external stimulation degradation is summarized briefly. Next, we have outlined the applications of nanomaterials in bioimaging. Finally, we have focused on some typical examples of biodegradable nanomaterials in radiotherapy (RT), photothermal therapy (PTT), starvation therapy, photodynamic therapy (PDT), chemotherapy, chemodynamic therapy (CDT), sonodynamic therapy (SDT), gene therapy, immunotherapy and combination therapy.

Abstract
Clinical photodynamic therapy (PDT) only has a limited cancer therapeutic effect and typically leads to a more hypoxic milieu owing to the hypoxic conditions of the solid tumor microenvironment that limit the singlet oxygen (1O2), generation. To address this issue, the PDT, in combination with hypoxia-activated prodrugs, has recently been investigated as a possible clinical treatment modality for cancer therapy. By cross-linking the photosensitizer tetra(4-hydroxyphenyl)porphine (THPP) and a 1O2-cleavable thioketal (TK) linker, a multifunctional nanoscale covalent organic framework (COF) platform with a high porphyrin loading capacity was synthesized, which significantly improve the reactive oxygen species (ROS) generation efficiency and contributes to PDT. As-synthesized THPPTK-PEG nanoparticles (NPs) possess a high THPP photosensitizer content and mesoporous structure for further loading of the hypoxia-responsive prodrug banoxantrone (AQ4N) into the COF with a high-loading content. The nano-carriers surfaces are coated with a thick PEG coating to promote their dispersibility in physiological surroundings and therapeutic performance. When exposed to 660 nm radiation, such a nanoplatform can efficiently create cytotoxic 1O2 for PDT. Similarly, oxygen intake may exacerbate the hypoxic environment of the tumor, inducing the activation of AQ4N to achieve hypoxia-activated cascade chemotherapy and increased treatment efficacy. This study provides a new nanoplatform for photodynamic-chemical synergistic therapy and offers critical new insights for designing and developing a multifunctional supramolecular drug delivery system. STATEMENT OF SIGNIFICANCE: Here, we designed a laser-activated hypoxia-responsive nanoscale COF nanoplatform for hypoxia-activated cascade chemotherapy and PDT. When exposed to laser light, thus this nanoplatform can efficiently create cytotoxic 1O2 for PDT while consuming oxygen at the tumor location. However, increased oxygen consumption can exacerbate the tumor's hypoxic environment, causing AQ4N to become active, allowing for programmed hypoxia-triggered cascade chemotherapy and improved therapeutic efficacy. In addition, this innovative nanoscale COF nanoplatform allows for laser-controlled drug delivery in specific areas, which dramatically improves tumor inhibition. This research suggests a method for attaining ultrasensitive drug release and effective cascade therapy for cancer treatments.

Abstract
For photothermal therapy (PTT), the improved targeting can decrease the dosage and promote the therapeutic function of photothermal agents, which would effectively improve the antitumor effect. The tumor microenvironment (TME) and cells are targets in designing intelligent and responsive theranostics. However, most of these schemes have been limited to the traditional visible and first near-infrared (NIR-I) regions, eager to expand to the second near-infrared (NIR-II) window. We designed and synthesized a polyethylene glycol conjugated and disulfide-modified macromolecule fluorophore (MPSS). MPSS could self-assemble into core-shell micelles in an aqueous solution (MPSS-NPS), while the small molecule probes were in a high aggregation arrangement inside the nanoparticle. The pronounced aggregation quenching (ACQ) effect caused them to the "sleeping" state. After entering the tumor cells, the disulfide bonds in MPSS-NPS broke in response to a high concentration of glutathione (GSH) in TME, and the molecule probes were released. The highly aggregated state was effectively alleviated, resulting in distinct absorption enhancement in the near-infrared region. Therefore, the fluorescence signal was recovered, and the photothermal performance was triggered. In vitro and in vivo studies reveal that the Nano-system is efficient for the smart NIR-II fluorescence imaging-guided PTT, even at a low dosage and density of irradiation.

Abstract
Conventional photosensitizers (PSs) often show poor tumor retention and are rapidly cleared from the bloodstream, which is one of the key hindrances to guarantee precise and efficient photodynamic therapy (PDT) in vivo. In this work, a photosensitizer assembly nanosystem that sharply enhances tumor retention up to ≈10 days is present. The PSs are synthesized by meso-substituting anthracene onto a BODIPY scaffold (AN-BDP), which then self-assembles into stable nanoparticles (AN-BDP NPs) with amphiphilic block copolymers due to the strong intermolecular π-π interaction of the anthracene. Additionally, the incorporated anthracene excites the PSs, producing singlet oxygen under red-light irradiation. Although AN-BDP NPs can completely suppress regular test size tumors (≈100 mm3 ) by one-time radiation, only 12% tumor growth inhibition rate is observed in the case of large-size tumors (≈350 mm3 ) under the same conditions. Due to the long-time tumor retention, AN-BDP NPs allow single-dose injection and three-time light treatments, resulting in an inhibition rate over 90%, much more efficient than single-time radiation of conventional clinically used PSs including chlorin-e6 (Ce6) and porphyrin with poor tumor retention. The results reveal the importance of long tumor retention time of PSs for efficient PDT, which can accelerate the clinical development of nanophotosensitizers.

Abstract
By combining the anionic salt meso-tetra(4-carboxyphenyl)porphyrin (TCPP4−) and the Keggin polyoxometalate cation cluster [Al13O4(OH)24(H2O)12]7+via a simple ion-exchange method, a hybrid (C48H26N4O8)[Al13O4(OH)24(H2O)12]2(OH)10·18H2O (Al13–TCPP) was prepared and thoroughly characterized as a prototype of polyoxometalate–porphyrin hybrids for the photocatalytic degradation of the mustard gas simulant 2-chloroethyl ethyl sulfide (CEES). The experimental results showed that the catalytic degradation rate of CEES in the presence of Al13–TCPP reached 96.16 and 99.01% in 180 and 90 min in methanol and methanol–water solvent mixture (v/v = 1 : 1), respectively. The reaction followed first-order reaction kinetics, and the half-life and kinetic constant in methanol and solvent mixture were 39.8 min, −0.017 min−1 and 14.7 min, −0.047 min−1. Mechanism analysis indicated that under visible light irradiation in air, CEES was degraded through a combination of oxidation and alcoholysis/hydrolysis in methanol and the methanol–water solvent mixture. The superoxide radical (O2˙−) and singlet molecular oxygen (1O2) generated by Al13–TCPP selectively oxidized CEES into a non-toxic sulfoxide. The singlet oxygen capture experiments showed that Al13–TCPP (Φ = 0.236) had a higher quantum yield of singlet oxygen generation than H4TCPP (Φ = 0.135) under visible light irradiation in air. The material Al13–TCPP has good reusability, and the degradation rate of CEES can still reach 98.37% after being recycled five times. A hybrid Al13–TCPP was thoroughly characterized as a prototype of polyoxometalate–porphyrin hybrids for the photocatalytic degradation of the mustard gas simulant 2-chloroethyl ethyl sulfide (CEES).![]()

Abstract
Photodynamic therapy (PDT) is showing great potential in the treatment of cancer diseases, and photosensitizers play crucial roles in absorbing the energy of light and generating reactive oxygen species (ROS) during PDT. Most of the photosensitizers bearing macrocyclic structures have strong hydrophobicity and suffer from the π-π interaction and undesired aggregation caused quenching (ACQ), which severely limit the PDT efficacy. Moreover, the continuous oxygen consumption during PDT also leads to the upregulated expression of hypoxia-inducible factor-1α (HIF-1α), which can aggravate the growth of tumors. To overcome the abovementioned problems, polymerized photosensitizers repelled by flexible thioketal linkers were designed and synthesized using a multicomponent polymerization (MCP) method to afford the poly-porphyrins with high molecular weight (Mw > 20 000 g/mol) under room temperature. The ACQ effect could be significantly inhibited by introducing flexible chains and increasing Mw, leading to the improvement in the singlet oxygen quantum yield and phototoxicity simultaneously. An HIF-1α inhibitor, Lificiguat (YC-1) was synthesized as a chemodrug and codelivered with poly-porphyrins to decrease the expression of HIF-1α and inhibit tumor growth under hypoxia. With the synergistic PDT and chemotherapy, poly-porphyrin/YC-1 micelles showed excellent therapeutic antitumor efficacy both in vitro and in vivo.

Abstract
Photodynamic therapy (PDT) holds great potential in cancer treatment due to the advantages of non-invasiveness, negligible side-effect, and high spatiotemporal selectivity. Porphyrin is the most widely used photosensitizer in clinical treatment. However, its PDT efficacy is always limited by the undesired aggregation caused quenching (ACQ) effect originating from the planar and rigid structure. In this work, a linear polymeric porphyrin with "structure defects" was developed to overcome the ACQ effect for most of the photosensitizers with conjugated macrocycles. Compared to porphyrin monomers, poly-porphyrins could improve singlet oxygen generation ability, and the singlet oxygen quantum yield enhanced with increasing molecular weight of poly-porphyrins. To achieve efficient in vivo PDT, PEG and acetazolamide were conjugated to the optimized poly-porphyrins to afford pP-PEG-AZ nanoparticles (pP-PEG-AZ NPs) with excellent stability, efficient in vitro intracellular internalization, negligible dark-toxicity, notable photo-toxicity, and in vivo anti-cancer efficacy based on combined PDT and anti-angiogenesis therapy.

Abstract
Successful gene therapy is highly dependent on the efficiency of gene delivery, which is mostly achieved by the carrier. Current gene carriers are generally nontherapeutic and take over most of the proportion in the delivery systems. Therefore, a library of polymerized and cationic photosensitive drugs (polyphotosensitizers, pPSs) with HIF-1α siRNA delivery capability is constructed to realize using "drug" to deliver "gene". The pPS component acts as both a therapeutic carrier for intracellular HIF-1α siRNA delivery and a photosensitive drug with photodynamic therapy (PDT). A reactive oxygen species (ROS)-cleavable linker is used to polymerize PS, allowing the successful segregation of PS monomers in space, avoiding the undesired aggregation-caused quenching (ACQ) effect and enhancing the in vitro and in vivo PDT effect. The complexes formed by pPSs and HIF-1α siRNA exhibited desired siRNA condensation and serum stability at the optimal conditions (pPSs with guanidines/siRNA weight ratio of 15), efficient intracellular internalization, and gene-silencing efficiency (60%) compared with commercial available transfection reagents (40%), as well as synergistic in vitro and in vivo phototoxicity for the combination PDT-gene therapy toward cancer treatment. This study provides a promising paradigm for the design of both the gene delivery carrier and the photosensitizer, as well as for broad utilities in the combination therapy toward cancer treatment.

Abstract
The photosensitizers (PS) play a vital role in photodynamic therapy (PDT), but the clinical therapeutic effect is limited by its low solubility, easy aggregation and lack of selective tumor uptake. Hence, some biocompatible materials such as poly(amino acid) have been chosen to deliver PS to solve these problems. In this study, we fabricated two kind of poly(amino acid)-based PS delivery systems by using poly (L-glutamic acid) (PLG) as the backbone material to physically encapsulate (P(T)) and chemically conjugate PS (PT), respectively. Moreover, the anticancer effect of these two PS delivery systems had been comparatively investigated. In vitro experiments verified that the delivery system of PT exhibited more effective treatment effect than that of P(T) because PS was chemically conjugated with PLG in PT which could obviously avoid the π-π stacking effect of PS and induced the aggregation. The less aggregation avoiding the quenching effect could result in an enhanced generation ability of reactive oxygen species to improve PDT treatment effect. Contrarily, the treatment effect of P(T) was lower due to the rigid structure and hydrophobic π-π stacking effect, in which the physically encapsulated PS was easier to aggregate and quench. Hence, the way how to combine carrier with drug is significant for satisfied treatment effect.

Abstract
Inspired by the dynamic morphology control of molecular assemblies in biological systems, we have developed pH-responsive transformable peptide-based nanoparticles for photodynamic therapy (PDT) with prolonged tumor retention times. The self-assembled peptide-porphyrin nanoparticles transformed into nanofibers when exposed to the acidic tumor microenvironment, which was mainly driven by enhanced intermolecular hydrogen bond formation between the protonated molecules. The nanoparticle transformation into fibrils improved their singlet oxygen generation ability and enabled high accumulation and long-term retention at tumor sites. Strong fluorescent signals of these nanomaterials were detected in tumor tissue up to 7 days after administration. Moreover, the peptide assemblies exhibited excellent anti-tumor efficacy via PDT in vivo. This in situ fibrillar transformation strategy could be utilized to design effective stimuli-responsive biomaterials for long-term imaging and therapy.

Abstract
Photodynamic therapy (PDT) leads to tumor hypoxia which could be utilized for the activation of hypoxia-activated prodrugs (HAPs). However, conventional photosensitizer-loaded nanoformulations suffer from an aggregation-caused quenching (ACQ) effect, which limits the efficiency of PDT and synergistic therapy. Herein, prodrug-nanoparticles (NPs) are prepared by the self-assembly of heterodimeric prodrugs composed of pyropheophorbide a (PPa), hypoxia-activated prodrug PR104A, and a thioether or thioketal linkage. In addition, a novel dual-modality drug release pattern is proposed on the basis of the structural states of prodrug-NPs. Under light irradiation, PR104A is released via photoinduced electron transfer (PET) due to the aggregation state of prodrugs. With the disassembly of prodrug-NPs, the ACQ effect is relieved, and PPa produces singlet oxygen which further promotes the reactive oxygen species (ROS)-sensitive release of PR104A. Such prodrug-NPs turn the disadvantage of the ACQ effect to facilitate drug release, demonstrating high-efficiency synergy in combination with PDT and hypoxia-activated therapy.

Abstract
Photodynamic therapy (PDT) has the advantages of low toxicity and specificity, but photosensitizers usually fail to accumulate efficiently at the tumor site. In this study, a new multifunctional nano-drug delivery system was exploited by a biomimetic strategy to improve the PDT effects. The self-assembled methoxy poly(ethylene glycol)-poly(lactide-co-glycolide) (mPEG-PLGA) nanoparticles encapsulated with the photosensitizer chlorin e6 (Ce6) by microfluidics were employed as the nano-core, followed by coating red blood cell (RBC) membranes as the biomimetic agent to prolong the circulation time in vivo. In order to boost the therapeutic effect, doxorubicin (Dox) was preloaded into RBC nanovesicles. The cell membrane surface was modified with folic acid (FA) to further enhance the tumor targeting efficiency. The prepared biomimetic nanoparticles with a homogeneous size (70 nm) can trigger sufficient reactive oxygen species (ROS), leading to significant tumor ablation without side effects. In addition, the system had high tumor targeting efficiency, with an increase of 25% compared with no FA-modified nanoparticles. Therefore, this biomimetic multifunctional nanodrug delivery system possesses a prolonged circulation time and higher tumor targeting efficiency and can exert better tumor cytotoxicity for improved PDT due to homophilic targeting in vivo.

Abstract
A simple and green layer-by-layer assembly strategy is developed for the preparation of a highly bioavailable nanocomposite photosensitizer by assembling near-infrared (NIR) light-sensitive porphyrin/G-quadruplex complexes on the surface of a highly biocompatible nanoparticle that is prepared via Zn2+-assisted coordination self-assembly of an amphiphilic amino acid. After being efficiently delivered to the target site and internalized into tumor cells via enhanced permeability and retention effect and interactions between aptamers and tumor markers, the as-prepared nanoassembly can be directly used as an NIR light-responsive photosensitizer for tumor photodynamic therapy (PDT) since the porphyrin/G-quadruplex complexes are exposed on the nanoassembly surface and kept in an active state. It can also disassemble under the synergistic stimuli of an acidic pH environment and overexpressed glutathione, leasing more efficient porphyrin/G-quadruplex composite photosensitizers while reducing the interference caused by glutathione-dependent 1O2 consumption. Since the nanoassembly can work no matter if it is disassembled or not, the compulsory requirement for in vivo photosensitizer release is eliminated, thus resulting in the great improvement of the bioavailability of the photosensitizer. The PDT applications of the nanoassembly were well demonstrated in both in vitro cell and in vivo animal experiments.

Abstract
Polymeric nanoparticles (NPs) have been widely established to deliver most of the hydrophobic chemo-drugs or photosensitizers (PSs) for cancer therapy. However, this strategy is usually hindered by the relatively low drug loading capacity and the undesired toxicity as well as the immunogenicity caused by the nontherapeutic, polymeric carriers. The carrier-free, drug self-delivery systems, in which the chemo-drugs or their prodrugs themselves formed the NPs without the addition of nontherapeutic carriers, have been extensively developed to achieve a high drug loading capacity and low systemic toxicity. However, most of the driving forces to form the NPs were based on the strong hydrophobic interactions, which were the undesired forces for the porphyrin-based hydrophobic PSs due to the parasitic aggregation-caused quenching effect. Herein, the zwitterionic, water-soluble, and reactive oxygen species (ROS)-cleavable poly-photosensitizers (pPSs) were prepared by the polymerization method, which spontaneously introduced different charges associated with the "desired electrostatic effect" and reduced the "undesired aggregation" by separating the PS monomers using flexible and ROS-cleavable linkers. The obtained pPS could be self-assembled into the nanocomplexes based on the electrostatic effect with a high PS loading capacity, improved singlet oxygen generation ability, and efficient phototoxicity. Upon poly(ethylene glycol) (PEG) or hyaluronic acid (HA) coating on the surface, both pPS/PEG and pPS/HA complexes exhibited enhanced stability under physiological environments and excellent in vivo antitumor efficacy. Moreover, HA-coated complexes also exhibited active tumor targeting. Such a polymerization strategy comprehensively addressed the parasitic issues for the hydrophobic PS self-delivery system in the photodynamic therapy area.
