A new kind of redox responsive nanoparticles was prepared through the modification and crosslinking reaction of xanthan gum. The nanoparticles had regular spherical shapes with diameters ranging from 110 to 180 nm. The nanoparticles showed good redox responsiveness. Doxorubicin (DOX) was loaded in the nanoparticles via ionic interaction with SO3-, for increasing the drug loading rate and avoiding drug leakage. The in vitro drug release could be controlled by pH and reduction conditions simulated to the internal environment of tumor cells. The nanoparticles were biocompatible and could be potentially applied as anti-cancer drug vehicles for targeted release.

A series of isocyanate-free polyurethanes (NIPUs), showing an intrinsic thermo-healing performance, have been synthesized from sustainable vegetable oil-based cyclic carbonates and bio-based amines. The bio-based contents of the NIPUs are higher than 78%. Their thermo-mechanical and self-healing performances are tailored simply by varying the feed ratios of the amines employed. The biomass linoleic acid dimer-based diamine plays a positive role in maintaining the higher thermal stability and good elasticity of the prepared NIPUs, the cycloaliphatic isophorone diamine contributes to high tensile strength, and cysteine-derived disulfide-containing cystamine (CA) enhances the self-healing efficiency. The combination of intrinsic hydrogen bonds existed in the NIPU matrix with the dynamic exchange reactions of disulfide bonds and the enhanced flexibility of NIPU networks results in 98.1% self-healing efficiency at 25 degrees C. The contributions of disulfide bonds and hydrogen bonds to the healing efficiency were estimated by adjusting the composition of NIPUs, showing that the contribution of disulfide bonds to the healing ability is about 45.3% even at a low amount of CA (6.0 wt%).

Chemically crosslinked recyclable photodeformable azobenzene (azo) polymer actuators with good stability (toward organic solvents and higher temperatures) and high processability and reconstruction ability hold great promise in many applications, but their development remains a challenging task. Herein, we report on for the first time a facile and highly efficient post-crosslinking method for addressing this issue. It involves first the synthesis of side-chain polymers bearing N-hydroxysuccinimide (NHS) carboxylate-substituted azo mesogens, fabrication of uniaxially oriented fibers from these azo polymers by the simple melt spinning method, and their subsequent post-crosslinking with cystamine (a diamine containing a disulfide bond) under mild conditions. The resulting chemically crosslinked fibers not only showed rapid and reversible photoinduced bending and unbending at ambient temperature as well as high mechanical strength and good solvent/heating stability, but also could be easily recycled into processable azo polymers in the presence of a reducing agent that can cleave the disulfide bond into thiol groups (i.e., tributylphosphine). In particular, the occurrence of the post-crosslinking reaction only on the thin surface layers of the azo polymer fibers afforded recycled polymers with large amounts of NHS carboxylate-substituted azo mesogens (together with a small amount of oxygen/heating-sensitive thiolsubstituted ones) in the first several (at least 5) recycling processes, thus allowing highly efficient reconstruction of photodeformable fibers with excellent photomobile properties by applying melt spinning and post-cross-linking (by using cystamine) methods. The strategy presented here opens the new possibility to the facile and efficient development of various advanced chemically crosslinked recyclable photodriven actuators.

Clinical application of drug cocktails for cancer therapy is limited by their severe systemic toxicity. To solve a catch-22 dilemma between safety and efficacy for drug cocktails, a heterotargeted nanococktail (PPPDMA) with traceless linkers is developed. In the PPPDMA nanogel, a heterotargeting strategy is employed to improve its tumor selective targeting efficacy by overcoming the cancer cell monoligand density limitation. Benefitting from its glutathione and reactive oxygen species responsiveness, the loaded paclitaxel and doxorubicin can be quickly and tracelessly released into the cytoplasm in their original form, which bestows upon PPPDMA nanogels the capability to overwhelm the processing capacity of the cancer cell’s P-glycoprotein efflux pump, and ultimately kill them without inducing side effects. The PPPDMA treatment reduced its tumor burden over 99% (in tumor weight) and 96% (in tumor number). Most importantly, no detectable tumor in more than half of the PPPDMA treated mice was observed. It is concluded that traceless linker and heterotargeted nanococktail strategy can be a safe and effective approach for cancer treatment.

Nanoparticles with active-targeting and stimuli-responsive behavior are a promising class of engineered materials able to recognize the site of cancer disease, targeting the drug release and limiting side effects in the healthy organs. In this work, new dual pH/redox-responsive nanoparticles with affinity for folate receptors were prepared by the combination of two amphiphilic dextran (DEX) derivatives. DEXFA conjugate was obtained by covalent coupling of the polysaccharide with folic acid (FA), whereas DEXssPEGCOOH derived from a reductive amination step of DEX was followed by condensation with polyethylene glycol 600. After self-assembling, nanoparticles with a mean size of 50 nm, able to be destabilized in acidic pH and reducing media, were obtained. Doxorubicin was loaded during the self-assembling process, and the release experiments showed the ability of the proposed system to modulate the drug release in response to different pH and redox conditions. Finally, the viability and uptake experiments on healthy (MCF-10A) and metastatic cancer (MDA-MB-231) cells proved the potential applicability of the proposed system as a new drug vector in cancer therapy.

Doxorubicin (DOX) resistance, which results in a reduced accumulation of DOX in the nucleus and hence decreased DNA damage, is a major challenge for chemotherapy against hepatocellular carcinoma. In this paper, we combined chemotherapy with photodynamic therapy (PDT) to combat DOX-resistant human hepatocellular carcinoma cells. We have prepared the polymeric micelles conjugating with DOX and zinc(II) phthalocyanine (ZnPc) through a pH-responsive hydrazone linker and a glutathione (GSH)-responsive disulfide linker, respectively. The polymeric micelles (DOX-ZnPc-micelles) exhibited a spherical shape with a size of about 98 mn diameter and showed excellent stability in aqueous solution. Due to the self-quenching of the ZnPc inside the micelles, DOX-ZnPc-micelles did not emit fluorescence upon red light irradiation. Drug release experiments verified that DOX and ZnPc could be released under acidic conditions and reducing environments, respectively. A higher concentration of DOX was internalized into DOX-resistant R-HepG2 cells through the delivery of polymeric micelles when compared with the free DOX, hence DOX-ZnPc-micelles exhibited a significant enhancement in anticancer activity. The IC50 value of DOX against R-HepG2 cells was found to be 21 mu M when combined with PDT and it was 5-fold less than that of a single treatment of DOX (102 mu M). The DOX-ZnPc-micelles could induce cell apoptosis and necrosis on R-HepG2 cells by combined therapeutic modalities, while these micelles induced only apoptosis on IiepG2 cells. We have demonstrated that utilization of polymeric micelles can significantly enhance the cellular uptake and cytotoxicity of DOX against R-HepG2 cells when compared with free DOX. Moreover, PDT can act as an adjuvant therapeutic modality and combine with chemotherapy to further improve therapeutic efficacy. Overall speaking, DOX-ZnPc-micelles can overcome DOX resistance and induce a synergistic therapeutic effect against DOX-resistant R-HepG2 cells, hence improving the therapeutic efficacy when compared with monotherapy.

Classic dendrimers are not used in many specific applications such as simultaneous loading of different drugs due to the existence of identical end groups. The possibility of designing the structure in dendrimers paves the way to synthesize more complicated dendrimers. This includes the creation of various types of peripheral groups on the surface of dendrimers to synthesize for example Janus dendrimers. Nowadays, three main methods are proposed for the synthesis of Janus dendrimers in which the high amount of conventional dendrimers is produced. The goal of this work is to develop a new method for synthesis of Janus dendrimers without production of conventional dendrimers. The present method has three main stages for the synthesis of Janus dendrimers including synthesis of 5th generation PPI dendrimer with cystamine core and hydrophobic surface, conversion of disulfide bonds to thiol group using a structure scission approach, and the formation of PAMAM hydrophilic dendrons with amine end groups. Different analyses including FT-IR, NMR, DLS, and GPC are used to prove the success of the synthesis route. Also, due to application of dendrimers in drug delivery including solubility improvement of hydrophobic drugs, Janus dendrimers are used to improve solubility of tetracycline and dexamethasone in presence of different generations of Janus dendrimers. Since the Janus dendrimers have both hydrophilic and hydrophobic ends, as well as having numerous terminal groups and numerous internal cavities, they have resulted in significant improvements in drug solubility. Also, solubility of the two hydrophobic drugs in water was increased by increasing concentration and generation of dendrimer.

Soft poly(N-vinylcaprolactam) (PNVCL) based nanogels were prepared and surface-decorated with gold nanoparticles (AuNPs). The applicability of the hybrid nanogels (PNVCL-AuNPs) as carriers for low molar mass substances was of special interest. AuNPs protected with a mixture of 11-azidoundecanothiol and 11-mercaptoundecanoic acid were bound to propargyl functionalized PNVCL based nanogels. Acidic groups on the surfaces of AuNPs and PNVCL based nanogels stabilize the particle dispersions against precipitation above the phase transition temperature of PNVCL. Both the neat PNVCL nanogels and the PVCL-AuNPs shrink upon heating the dispersions. Even though the AuNPs are mainly located in the soft surface layer of the nanogels, the PNVCL-AuNPs respond to visible light as well as to radio-frequency (RF) irradiation by shrinking due to the AuNPs acting as nanoheaters. Interactions of linear PNVCL, PNVCL nanogels and PNVCL-AuNPs with two fluorescent probes were studied as function of increasing temperature. Once bound to the polymer the fluorescent probe may or may not be released from it, depending on its polarity and water solubility. Presence of AuNPs changed the release behavior of the water soluble charged fluorescent probe from the nanogels.

Novel acid/alkali/corrosion potential triple stimuli -responsive smart nanocontainers (TSR-SNs) were successfully assembled to regulate the release of an encapsulated corrosion inhibitor, benzotriazole (BTA), by installing specially structured bistable pseudorotaxanes as supramolecular nanovalves onto orifices of mesoporous silica nanoparticles. In normal conditions, BTA molecules were sealed in the mesopores. Upon any stimulus of acid, alkali, or corrosion potential, BTA molecules were quickly released because of the open states of the supramolecular nanovalves. TSR-SNs as smart nanocontainers were added into the SiO2 ZrO2 sol gel coating to fabricate a stimuli-feedback, corrosion-compensating self-healing anticorrosion coating (SF-SHAC). Compared with the conventional pH-responsive smart nanocontainers synthesized for the SHAC, TSR-SNs not only respond to the pH changes occurring on corrosive microregions but also, and more importantly, feel the corrosion potential of aluminum alloys and give quick feedback. This design avoids wasting smart nanocontainers because of the local-dependent, gradient pH stimulus intensities and obviously enhances the response sensitivity of the SF-SHAC. Electrochemical impedance spectroscopy and salt spray tests prove the excellent physical barrier of the SF-SHAC. Through scanning vibrating electrode technique measurements, the SF-SHAC doped with TSR-SNs demonstrates inhibiting rates for corrosive microcathodic/anodic current densities that are faster than other control SHACs. The new incorporated corrosion potential-responsive function ensures the efficient working efficiency of TSR-SNs and makes full use of the preloaded corrosion inhibitors as repair factors.

In this paper, a novel redox-responsive nanoparticles has been designed for targeted delivery of docetaxel (DTX). Chondroitin sulfate (CS) was used to construct the nanoparticles due to the ability of tumor targeting through binding with CD44 receptor that overexpresses on the surfaces of various tumor cells. A redox-responsive small-molecular DTX prodrug was prepared through modifying with cystamine containing disulfide bonds (Cys-DTX). Then the DTX prodrug was grafted to the CS to construct the amphiphilic polymer (CS-ss-DTX). Further, Cys-DTX/CS-ss-DTX nanoparticles were formed by self-assembly of amphiphilic polymer and incorporation of free Cys-DTX prodrug. This category of nanosized DTX delivery system was expected for not only exhibiting high permeability and cytotoxicity of Cys-DTX prodrug, but also targeting transportation of encapsulated redox-responsive Cys-DTX prodrug. According to results of related researches on physicochemical properties and biological evaluation, the novel redox-responsive Cys-DTX/CS-ss-DTX nanoparticles increased amount of DTX released from the nanoparticles in reductive environment, improved permeability in tumor tissues, enhanced cytotoxicity and decreased side effects compared with free DTX. All of these results showed that this kind of Cys-DTX/CS-ss-DTX nanoparticles were worthy of being expectation in tumor chemotherapy in future.
