Biomimetic nanoparticles to enhance the reverse cholesterol transport for selectively inhibiting development into foam cell in atherosclerosis. J Nanobiotechnology 2023; 21:307.

Abstract
A disorder of cholesterol homeostasis is one of the main initiating factors in the progression of atherosclerosis (AS). Metabolism and removal of excess cholesterol facilitates the prevention of foam cell formation. However, the failure of treatment with drugs (e.g. methotrexate, MTX) to effectively regulate progression of disease may be related to the limited drug bioavailability and rapid clearance by immune system. Thus, based on the inflammatory lesion "recruitment" properties of macrophages, MTX nanoparticles (MTX NPs) camouflaged with macrophage membranes (MM@MTX NPs) were constructed for the target to AS plaques. MM@MTX NPs exhibited a uniform hydrodynamic size around ~ 360 nm and controlled drug release properties (~ 72% at 12 h). After the macrophage membranes (MM) functionalized "homing" target delivery to AS plaques, MM@MTX NPs improved the solubility of cholesterol by the functionalized β-cyclodextrin (β-CD) component and significantly elevate cholesterol efflux by the loaded MTX mediated the increased expression levels of ABCA1, SR-B1, CYP27A1, resulting in efficiently inhibiting the formation of foam cells. Furthermore, MM@MTX NPs could significantly reduce the area of plaque, aortic plaque and cholesterol crystals deposition in ApoE-/- mice and exhibited biocompatibility. It is suggested that MM@MTX NPs were a safe and efficient therapeutic platform for AS.

Abstract
Drug delivery systems (DDS) triggered by local microenvironment represents the state-of-art of nanomedicine design, where the triggering hallmarks at intracellular and subcellular levels could be employed to exquisitely recognize the diseased sites, reduce side effects, and expand the therapeutic window by precisely tailoring the drug-release kinetics. Though with impressive progress, the DDS design functioning at microcosmic levels is fully challenging and underexploited. Here, we provide an overview describing the recent advances on stimuli-responsive DDSs triggered by intracellular or subcellular microenvironments. Instead of focusing on the targeting strategies as listed in previous reviews, we herein mainly highlight the concept, design, preparation and applications of stimuli-responsive systems in intracellular models. Hopefully, this review could give useful hints in developing nanoplatforms proceeding at a cellular level.

Abstract
Paclitaxel (PTX), etoposide (ETP), and rapamycin (RAPA) have different mechanisms, allowing multiple pathways to be targeted simultaneously, effectively treating various cancers. However, these drugs have a low hydrosolubility, limiting clinical applications. Therefore, we used pH-sensitive polymeric micelles to effectively control the drug release in cancer cells and to improve the water solubility of PTX, ETP, and RAPA. The synergistic effect of PTX, ETP, and RAPA was evaluated in gastric cancer, and the combination index values were evaluated. Thin-film hydration was used to prepare PTX/ETP/RAPA-loaded mPEG-pH-PCL micelles, and various physicochemical properties of these micelles were evaluated. In vitro cytotoxicity, pH-sensitivity, drug release profiles, in vivo pharmacokinetics, and biodistribution studies of PTX/ETP/RAPA-loaded mPEG-pH-PCL micelles were evaluated. In the pH-sensitivity evaluation, the size of the micelles increased more rapidly at a pH of 5.5 than at a pH of 7.4. The release rate of each drug increased with decreasing pH values in PTX/ETP/RAPA-loaded mPEG-pH-PCL micelles. In vitro and in vivo studies demonstrated that PTX/ETP/RAPA-loaded mPEG-pH-PCL micelles exhibit different drug release behaviors depending on the pH of the tumor and normal tissues and increased bioavailability and circulation time in the blood than solutions. Therefore, we propose that PTX/ETP/RAPA- loaded mPEG-pH-PCL micelles are advantageous for gastric cancer treatment in drug delivery systems.

Abstract
Carriers are protective transporters of drugs to target cells, facilitating therapy under each points of view, such as fast healing, reducing infective phenomena, and curing illnesses while avoiding side effects. Over the last 60 years, several scientists have studied drug carrier properties, trying to adapt them to the release environment. Drug/Carrier interaction phenomena have been deeply studied, and the release kinetics have been modeled according to the occurring phenomena involved in the system. It is not easy to define models’ advantages and disadvantages, since each of them may fit in a specific situation, considering material interactions, diffusion and erosion phenomena, and, no less important, the behavior of receiving medium. This work represents a critical review on main mathematical models concerning their dependency on physical, chemical, empirical, or semi-empirical variables. A quantitative representation of release profiles has been shown for the most representative models. A final critical comment on the applicability of these models has been presented at the end. A mathematical approach to this topic may help students and researchers approach the wide panorama of models that exist in literature and have been optimized over time. This models list could be of practical inspiration for the development of researchers’ own new models or for the application of proper modifications, with the introduction of new variable dependency.

Abstract
Herein, a new nanodrug of azobenzene-functionalized interfacial cross-linked reverse micelles (AICRM) with 5-fluorouracil loading (5-FU@AICRM) is reported. Upon irradiation with 530 nm light in water, the surface azobenzenes of the nanoparticles change from polar cis-conformation to nonpolar trans-conformation, resulting in the aggregation of 5-FU@AICRM within minutes. Simultaneously, the conformation change unlocks hydrophilic 5-FU with a strong water immigration propensity, allowing them to spray out from the AICRM quickly. This fast release ensures a thorough release of the drug, before the aggregates are internalized by adjacent cells, making it possible to achieve deep tissue penetration. A study of in vivo anticancer activity in A549 tumor-bearing nude mice shows that the tumor inhibition rate (TIR) of 5-FU@AICRM is up to ≈86.2%, 31.6% higher than that of group without green light irradiation and 20.7% higher than that of carmofur (CF, a hydrophobic analog of 5-FU)-loaded AICRM (CF@AICRM), in which CF is released slowly under light irradiation because of its hydrophobicity. Fast drug release upon nanodrug aggregation provides a good solution for balancing the contradiction of "aggregation and penetration" in tumor treatment with nanodrugs.

Abstract
Traditional antibacterial treatments, such as chlorhexidine (CHX), destroy cariogenic biofilms. However, they exert negative effects in clinical applications, for example, teeth staining, taste disturbance and harm to oral tissue after a long-term exposure. Therefore, biocompatible strategies for efficient antibacterial drug delivery are in high demand. In this study, aimed at dental caries therapy enhancement, we designed a pH-responsive nanocarrier system, capable of releasing CHX in an acidic environment within cariogenic biofilms. Cationic poly(ethylene glycol)-block-poly(2-(((2-aminoethyl)carbamoyl)oxy)ethyl methacrylate) (PEG-b-PAECOEMA) was synthesized first. Modification of PAECOEMA by citraconic anhydride (CA) forms negatively charged PEG-b-PAECOEMA/CA, which could assemble into core-shell polyionic complex micelles (PICMs) when mixed with cationic CHX via electrostatic interactions. PICMs are stable in healthy neutral oral microenvironments with CHX encapsulated in the core and PEG shell exposed. Once in acidic milieu within caries-producing biofilms, they rapidly disassemble and release CHX cargo owing to degradation of citraconic amide groups. Molecular structures of the above copolymers were confirmed using 1H NMR and gel permeation chromatography (GPC) analysis. The pH-dependent degradation rates of citraconic amide in PEG-b-PAECOEMA/CA copolymer were measured by fluorescamine method. Atomic force microscopy (AFM) studies confirmed successful assembly of well-defined spherical PICMs in aqueous solution. The disassembly of PICMs in acidic microenvironment was observed using dynamic light scattering (DLS). PICMs showed an obvious pH-dependent drug release profile when the pH changed from 7.4 to 5.5. More importantly, the micellar system could reduce drug toxicity of CHX and exhibited outstanding antibacterial capability in the biofilm of Streptococcus mutans. Micelles constructed from pH-sensitive PEG-b-PAECOEMA/CA are highly promising for dental caries therapy and provide guidelines for drug-delivery system design in other acidic pathologic systems.

Abstract
The development of the tumor-targeting ability of nanocarriers is of paramount importance for gene delivery into tumor lesions as well as to avoid biotoxicity. Here we report the synthesis of the polyethyleneimine-fluorescein isothiocyanate-folic acid (PEI-FITC-FA) polymer, which could condense the tumor suppressor pp53 to form nanocomplexes. These targeted nanocomplexes exhibited favorable physical properties including a small size of <100 nm, exploiting the enhanced permeability and retention effect and tumor-targeting ability by binding to the overexpressed FA receptors on tumor cell surfaces. In addition, once the nanocomplexes are accumulating in the tumor tissue, the target functional ligand, FA, can selectively recognize the over-expressed FA receptor and subsequently remain on the tumor cell surface, which can significantly promote the tumor cell uptake because of the time- and concentration-dependent internalization caused by the enhanced interaction between nanocomplex and tumor cell. Our results indicated that PEI-FITC-FA/pp53 nanocomplexes could be efficiently delivered into tumor cells, and subsequently induce tumor cell apoptosis. Thus, the targeted cationic polymer PEI-FITC-FA could be used as an advanced nanocarrier for gene delivery.

Abstract
The development of an intelligent biomaterial system that can efficiently accumulate at the tumor site and release a drug in a controlled way is very important for cancer chemotherapy. PEG is widely selected as a hydrophilic shell to acquire prolonged circulation time and enhanced accumulation at the tumor site, but it also restrains the cellular transport and uptake and leads to insufficient therapeutic efficacy. In this work, a PEG-detachable pH-responsive polymer that forms micelles from copolymer cholesterol grafted poly(ethylene glycol) methyl ether- Dlabile-poly(β-amino ester)- Dlabile-poly(ethylene glycol) methyl ether (MPEG- Dlabile-PAE- g-Chol) is developed to overcome the aforementioned challenges based on pH value changes among normal physiological, extracellular (pHe), and intracellular (pHi) environments. PEGylated doxorubicin (DOX)-loaded polymeric micelles (DOX-PMs) can accumulate at the tumor site via an enhanced permeability and retention effect, and the PEG shell is detachable induced by cleavage of the pHe-labile linker between the PEG segment and the main chain. Meanwhile, the pHi-sensitive poly(β-amino ester) segment is protonated and has a high positive charge. The detachment of PEG and protonation of PAE facilitate cellular uptake of DOX-PMs by negatively charged tumor cells, along with the escape from endo-/lysosome due to the "proton-sponge" effect. The DOX molecules are controlled release from the carriers at specific pH values. The results demonstrate that DOX-PMs have the capability of showing high therapeutic efficacy and negligible cytotoxicity compared with free DOX in vitro and in vivo. Overall, we anticipate that this PEG-detachable and tumor-acidity-responsive polymeric micelle can mediate effective and biocompatible drug delivery "on demand" with clinical application potential.

MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2017; 85:88-96.

Abstract
Curcumin has attracted increasing attentions in recent years due to its promising anticancer activities. However, the hydrophobicity of curcumin has limited greatly its efficacy in clinical trials. In this study, folate (FA)-receptor targeting mesoporous silica nanoparticles that promise high loadings of curcumin via pH-sensitive Schiff base reactions were constructed and examined for targeted delivery of curcumin. Such nano-delivery system showed significantly improved stability and biocompatibility of curcumin under physiological conditions. Further investigations demonstrated that this nanocarrier had high values of drug loading efficiency (9.5%) and pH-responsive drug release property. Moreover, the particles could be efficiently internalized by FA-receptor-rich MCF-7 cells through the receptor-mediated endocytosis, whereas FA-receptor-poor HEK-293T normal cells showed much lower endocytosis of the nanoparticles under the same conditions. The in vitro cytotoxicity assay indicated that the curcumin-loaded nanoparticles exhibited significantly enhanced cytotoxicity against MCF-7 cell than HEK-293T cells because of the higher cellular uptake efficiency of nanocarriers. More broadly, this work demonstrates a new type of mesoporous silica nanocarrier particularly useful for targeted and controlled drug release applications.

Abstract
OBJECTIVE This study was performed to investigate a novel pH-responsive nanocarrier based on modified nano graphene oxide (nGO) to promote the acid-triggered intracellular release of a poorly soluble drug, FTY720. METHODS To synthesize a drug conjugated to modified nGO, first the polyethylene glycol (PEG) was conjugated to nGO, then the produced PEG-nGO was functionalized with the anticancer drug, FTY720, through amide bonding. It was characterized by the scanning electron microscopy (SEM), the atomic force microscopy (AFM), the Fourier transform infrared (FTIR) spectroscopy and the UV-vis spectroscopy. In vitro drug release of the FTY720-conjugated PEG-nGO was evaluated at pH 7.4 and 4.6 PBS at 37 °C. Furthermore, the antineoplastic action of unloaded and drug-loaded carrier against the human breast adenocarcinoma cell line MCF7 was explored using MTT and BrdU assays. RESULTS Characterization methods indicated successful drug deposition on the surface of nGO. In vitro, drug release results revealed a significantly faster release of FTY720 from PEG-nGO at acidic pH, compared with physiological pH. The proliferation assays proved that the unloaded nGO had no significant cytotoxicity against MCF7 cells, while free FTY720- and FTY720-loaded PEG-nGO had an approximately equal cytotoxic effect on the MCF7 cells. It was found that the extended release characteristic of FTY720 was well fitted to Korsmeyer-Peppas model and the release profile of FTY720 from PEG-nGO is diffusion controlled. CONCLUSION PEGylated GO can act as a pH-responsive drug carrier to improve the efficacy of anticancer drug delivery.

Abstract
Advances in nanoparticle synthesis and engineering have produced nanoscale agents affording both therapeutic and diagnostic functions that are often referred to by the portmanteau 'nanotheranostics'. The field is associated with many applications in the clinic, especially in cancer management. These include patient stratification, drug-release monitoring, imaging-guided focal therapy and post-treatment response monitoring. Recent advances in nanotheranostics have expanded this notion and enabled the characterization of individual tumours, the prediction of nanoparticle-tumour interactions, and the creation of tailor-designed nanomedicines for individualized treatment. Some of these applications require breaking the dogma that a nanotheranostic must combine both therapeutic and diagnostic agents within a single, physical entity; instead, it can be a general approach in which diagnosis and therapy are interwoven to solve clinical issues and improve treatment outcomes. In this Review, we describe the evolution and state of the art of cancer nanotheranostics, with an emphasis on clinical impact and translation.

Abstract
Fe2+ plays an essential role for artemisinin (ART)-based drugs in anticancer therapy. As a result, it is important to realize these two agents' cotransport for improving antitumor efficacy. We utilized a kind of alternating magnetic field (AMF) and tumor-responsive material-mesoporous Fe3O4 (mFe3O4)-to encapsulate ART. After that, the outer surface of mFe3O4 was capped with multifunctional hyaluronic acid (HA), which was used not only as a smart gatekeeper but also as a tumor targeting moiety. In vitro and in vivo studies proved that ART can be encapsulated in HA-mFe3O4 and protected by HA coating which could effectively avoid premature release during in vivo circulation. HA-mFe3O4/ART could be taken up by MCF-7 tumor cells via CD44 receptor-mediated endocytosis and locate at acidic lysosome. Subsequently, "HA gate" could be degraded by acidity and hyaluronidase. Then this system synchronously released Fe2+ and ART at the same site. Fe2+ can nonenzymatically convert ART to ROS for killing cancer cells. Under AMF irradiation, HA-mFe3O4 could not only effectively convert electromagnetic wave into heat for tumor thermal therapy but also generate high levels of reactive oxygen species (ROS) for tumor dynamic therapy. These results demonstrated that the antitumor efficacy of HA-mFe3O4/ART in vivo significantly enhanced 3.7 times compared with free ART. Combining with AMF, it further improved 3.9 times (V/V0 of 0.11), suggesting the successful combined application of HA-mFe3O4/ART and AMF for tumor treatment. It is believed that HA-mFe3O4/ART is a promising system for Fe2+-dependent drugs to improve their therapeutic effect.

Abstract
PURPOSE Ruthenium complex is a potentially theranostic agent for cancer imaging and therapy, however its application is limited due to poor water-solubility and lack of tumor selectivity. To overcome the above drawbacks, pH-sensitive nanocapsule as a novel targeting carrier was designed to deliver ruthenium complex for treating xenograft tumor of mice. METHODS The core/shell structured nanocapsule with ruthenium complex tris(1,10-phenanthroline) ruthenium(II) complex (3P-Ru) as the core and a pH-sensitive polymeric material poly (2-diisopropylaminoethyl methacrylate)-block poly(2-aminoethyl methacrylate hydrochloride) (PbPS) as the shell was synthesized and characterized. Meanwhile, the nanocapsule was used to investigate cell viability and evaluate tissue distribution as well as preventing tumor growth efficacy in U251 stem cells tumor-bearing mouse model. RESULTS The nanocapsule had a size of 103.1 ± 11.3 nm, zeta potential of -40 ± 5.3 mV, EE of 76.7 ± 0.9%, LE of 25.4 ± 0.6% and it could control drug release under different pH conditions. The results of cell uptake showed that the fluorescent 3P-Ru loaded in the nanocapsule could be delivered into cells with high efficiency, and then significantly inhibited U251 proliferation in a concentration-dependent manner. After U251 stem cells were transplanted subcutaneously into mice, the 3P-Ru/PbPS nanocapsule (PbPS-Ru-NC) via intravenous administration could concentrate in tumor area and obviously prevent tumor growth. CONCLUSIONS The pH-sensitive nanocapsule as a antitumor agent carrier was able to effectively deliver 3P-Ru into gliomas cells, and cell growth was significantly inhibited both in vitro and in vivo. Such pH-sensitive nanocapsule for ruthenium complex delivery would have great potential application in tumor theranostics.

Abstract
Targeted delivery of therapeutic agents is an important way to improve the therapeutic index and reduce side effects. To design nanoparticles for targeted delivery, both enhanced tumor tissue accumulation/retention and enhanced cellular internalization should be considered simultaneously. So far, there have been very few nanoparticles with immutable structures that can achieve this goal efficiently. Hierarchical targeting, a novel targeting strategy based on stimuli responsiveness, shows good potential to enhance both tumor tissue accumulation/retention and cellular internalization. Here, the recent design and development of hierarchical targeting nanoplatforms, based on changeable particle sizes, switchable surface charges and activatable surface ligands, will be introduced. In general, the targeting moieties in these nanoplatforms are not activated during blood circulation for efficient tumor tissue accumulation, but re-activated by certain internal or external stimuli in the tumor microenvironment for enhanced cellular internalization.

Abstract
The therapeutic outcome of photodynamic therapy (PDT) with redaporfin (a fluorinated sulfonamide bacteriochlorin, F2BMet or LUZ11) was improved using Pluronic-based (P123, F127) formulations. Neither redaporfin encapsulated in Pluronic nor micelles alone exhibited cytotoxicity in a broad concentration range. Comprehensive in vitro studies against B16F10 melanoma cells showed that redaporfin-P123 micelles enhanced cellular uptake and increased oxidative stress compared with redaporfin-F127 or photosensitizer alone after short incubation times. ROS-sensitive fluorescent probes showed that the increased oxidative stress is due, at least in part, to a more efficient formation of hydroxyl radicals, and causes strong light-dose dependent apoptosis and necrosis. Tissue distribution and pharmacokinetic studies in tumor-bearing mice show that the Pluronic P123 formulation of redaporfin increases its bioavailability as well as the tumor-to-muscle and tumor-to-skin ratios, in comparison with Cremophor EL and Pluronic F127 formulations. Redaporfin in P123 was most successful in the PDT of C57BL/6J mice bearing subcutaneously implanted B16F10 melanoma tumors. Vascular-targeted PDT combining 1.5 mg kg(-1) redaporfin in P123 with a light dose of 74 J cm(-2) led to 100% complete cures (i.e., no tumor regrowth over one year post-treatment). This remarkable result reveals that modification of redaporfin with Pluronic block copolymers overcomes the resistance of melanoma cells to PDT possibly via increased tumor selectivity and enhanced ROS generation.

In order to modulate the drug release profiles, the hierarchical mesoporous silica nanoparticles (HMSNs) are fabricated by a two-step synthetic process. The HMSNs exhibit uniform spherical morphology with nanoscaled size, well mono-dispersed size distribution, and smooth surface. Because of the hierarchical pore structures with different mesoporous sizes and morphologies (partial open and partial blocked pores), the HMSNs can release the loaded drug in a controlled manner. The hierarchical mesoporous structures directed drug release profiles suggest a feasible strategy to tailor drug release behaviors. Meanwhile, the HMSNs exhibit good biocompatibility. Therefore, the HMSNs having tailorable drug release capacity would be a potential candidate to improve their therapeutic efficiency for drug delivery systems.

CS/PAA@TPGS/PLGA nanoparticles with intracellular pH-sensitive sequential release for delivering drug to the nucleus of MDR cells. Colloids Surf B Biointerfaces 2016; 145:716-727.

Abstract
Development of novel nano-drug delivery systems (NDDS) that can transport anticancer drugs into cell nuclei is still a highly desirable strategy for reversing multi-drug resistance (MDR) in cancer therapy. Herein, we designed and prepared a novel NDDS, designated S@L NPs, in which several smaller nanoparticles are contained within a larger nanoparticle. Our S@L NPs (CS/PAA/VP-16@TPGS/PLGA NPs) possess a structure in which smaller nanoparticles (Chitosan-Poly(acrylic acid) nanoparticles, CS/PAA NPs) containing the drug etoposide (VP-16) are loaded within a larger nanoparticle (Vitamin E d-a-tocopheryl polyethylene glycol 1000 succinate-modified poly(lactic-co-glycolic acid) nanoparticles, TPGS/PLGA NPs). The system utilizes intracellular pH gradients to achieve pH-sensitive sequential release within different intracellular domains of MDR cells. S@L NPs could be triggered to degrade and release CS/PAA/VP-16 NPs in the acid environment of the cytosol, endosomes or lysosomes, and CS/PAA/VP-16 NPs were capable of entering the nucleus through nucleopores. It is significant that CS/PAA/VP-16 NPs exhibit disaggregation in the alkaline environment of the nucleus and thereby release the contained anticancer drug. Further mechanistic studies showed that CS/PAA/VP-16 NPs escaped retention and degradation within lysosomes and protected the drug from P-glycoprotein-induced efflux. Simultaneously, S@L NPs enhanced the anticancer effect of the loaded drug by inducing autophagy and apoptosis of MDR cells. This novel NDDS may provide a promising platform for nuclear drug delivery for reversing MDR.

Abstract
Salecan is a novel linear extracellular polysaccharide with a linear backbone of 1-3-linked glucopyranosyl units. Salecan is suitable for preparing hydrogels for biomedical applications due to its prominent physicochemical and biological profiles. In this contribution, a variety of innovative semi-interpenetrating polymer network (semi-IPN) hydrogels consisting of Salecan and poly(methacrylic acid) (PMAA) were developed via free radical polymerization for controlled drug delivery. The successful fabrication of the semi-IPNs was verified by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and thermogravimetric (TGA) measurements. Scanning electron microscopy (SEM) and rheology analyses demonstrated that the morphological and mechanical behaviors of the resultant hydrogels were strongly affected by the contents of Salecan and cross-linker N,N'-methylenebis(acrylamide) (BIS). Moreover, the swelling properties of these hydrogels were systematically investigated, and the results indicated that they exhibited pH sensitivity. The drug delivery applications of such fabricated hydrogels were further evaluated from which doxorubicin (Dox) was chosen as a model drug for in vitro release and cell viability studies. It was found that the Dox release from the Dox-loaded hydrogels was significantly accelerated when the pH of the release media decreased from 7.4 to 5.0. Toxicity assays confirmed that the blank hydrogels had negligible toxicity to normal cells, whereas the Dox-loaded hydrogels remained high in cytotoxicity for A549 and HepG2 cancer cells. All of these attributes implied that the new proposed semi-IPNs serve as potential drug delivery platforms for cancer therapy.

Abstract
UNLABELLED A novel amphiphilic cholesterol-based block copolymer comprised of a polymethacrylate bearing cholesterol block and a polyethylene glycol block with reducible disulfide bonds (PC5MA-SS-PEO) was synthesized and evaluated as a redox-sensitive nanoparticulate delivery system. The self-assembled PC5MA-SS-PEO nanoparticles (SS-NPs) encapsulated the anticancer drug doxorubicin (DOX) with high drug loading (18.2% w/w) and high encapsulation efficiency (94.9%). DOX-encapsulated PC5MA-SS-PEO self-assembled nanoparticles (DOX-encapsulated SS-NPs) showed excellent stability and exhibited a rapid DOX release in response to dithiothreitol reductive condition. Importantly, following internalization by lung cancer cells, the reducible DOX-encapsulated SS-NPs achieved higher cytotoxicity than the non-reducible thioester NPs whereas blank nanoparticles were non-cytotoxic. Furthermore, in vivo imaging studies in tumor-bearing severe combined immunodeficiency (SCID) mice showed that the nanoparticles preferentially accumulated in tumor tissue with remarkably reduced accumulation in the healthy non-target organs. The results indicated that the SS-NPs may be a promising platform for cancer-cell specific delivery of hydrophobic anticancer drugs. FROM THE CLINICAL EDITOR The use of nanocarriers for drug delivery against tumors has been under intense research. One problem of using carrier system is the drug release kinetics at tumor site. In this article, the authors continued their previous study in the development of an amphiphilic cholesterol-based block copolymer with redox-sensitive modification, so that the payload drug could be released in response to the microenvironment. The interesting results should provide a new direction for designing future novel nanocarrier systems.

Abstract
A small, nano-sized, water-soluble polyrotaxane (PR) was synthesized using a highly efficient one-pot synthesis strategy in a homogeneous water system, formed from β-cyclodextrin-(COOH)2, poly(propylene glycol)bis(2-aminopropyl ether) (PPG, 2 kDa) and a mono-(6-azido-6-desoxy)-β-cyclodextrin stopper via room temperature click chemistry. β-cyclodextrin-(COOH)2 and PR were characterized by one- and two-dimensional NMR as well as by high resolution transmission electron microscopy (HR-TEM). The number of carboxyl groups in one PR was determined by 1H NMR. Two-dimensional diffusion-ordered NMR spectroscopy (2D DOSY) and nuclear Overhauser enhancement spectroscopy (2D NOESY) show that β-cyclodextrin-(COOH)2 and PPG successfully formed an inclusion complex. HR-TEM revealed the morphology of water-soluble PR as a spherical nanoparticle with a size of approximately 3.5 nm ± 1.5 nm. PR was labeled with rhodamine to assess its biocompatibility and cell membrane penetrability in vitro. The in vivo real-time fluorescent imaging biodistribution experiments indicated that water-soluble PR can actively target tumor sites using an enhanced permeability and retention (EPR) effect, with a significantly prolonged blood circulation time in tumor-bearing mice.
