Introducing clickable groups onto polymer microspheres allows the microspheres to be facilely functionalized via a click reaction. In this report, we have synthesized monodisperse PMMA microspheres with clickable double bonds on the surface by one-step RAFT-assisted dispersion photopolymerization using a cyclohexyl-containing macro-RAFT agent as a stabilizer. This macro-RAFT agent, named P(THPAA-b-AA)-TTC, was synthesized by RAFT-mediated block copolymerization of a cyclohexyl-containing monomer (THPAA, obtained by esterification of cis-1,2,3,6-tetrahydrophthalic with 2-hydroxyethyl acrylate) and acrylic acid. The obtained microspheres were analyzed by H-1 NMR and Iodometric method, indicating that the content of carbon double bonds on the microspheres increased with increasing the amount of P(THPAA-b-AA)-TTC in the polymerization feed. We then used a thiolated biotin to perform the photo-click reaction with the cyclohexene double bond on the micro spheres, thereby attaching the biotin unit onto the microspheres. The biotinylated PMMA microspheres were found to be able to effectively immobilize fluorescein isothiocyanate streptavidin (FITC-SAv) via the specific adsorption of biotin to streptavidin, and thus exhibited clear fluorescence under confocal microscope. This study provides a convenient and feasible way to prepare surface-functionalized microspheres, which has great potential in biological applications as well as other fields.

The replacement of the opposing nitrogen atoms in 1,4,8,11-tetraazacyclotetradecane (cyclam) with two sulfur atoms in 1,8-dithia-4,11-diazacyclotetradecane (dithiacyclam) enables the electrochemical reduction of protons and CO(2)via the corresponding nickel(ii) complex at more positive potentials. In addition, a 10-fold enhancement in the proton reduction rate of [Ni(dithiacyclam)](2+) relative to [Ni(cylcam)](2+) was observed. The study provides vital insight into Nature’s choice of employing predominantly sulfur based ligand platforms in achieving biological proton and CO2 reductions.

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.

Cancer cells have reductive and acidic environments as compared to the normal body cells. Development of reductive/acidic responsive polymersomes will play a major role in cancer therapy to trigger the release of the loaded drug. In our work, we synthesized three different reductive/acidic dual-responsive polymers, poly[(mPEG-SS-amino) (N,N-diisopropylethylenediamino)phosphazenes] (PPDPs) in different mole ratios of side groups. These PPDPs were characterized by H-1 NMR, P-31 NMR, FT-IR and GPC. After that, the PPDPs were allowed to self-assemble into drug-loaded polymersomes with high loading content and encapsulation efficiency of hydrophilic/hydrophobic anticancer drugs. The hydrophilic anticancer drug doxorubicin hydrochloride (DOX center dot HCl) and hydrophobic drug doxorubicin were used. These PPDPs-based polymersomes showed reductive/acidic stimuli-responsive release of anticancer drugs. Moreover, these polymersomes also exhibited suitable hydrodynamic diameters, which will facilitate the longtime circulation in bloodstream due to avoiding renal clearance and close contact to the tumor cells in vascular sections due to enhanced permeability and retention effect. Collectively, these developed polymersomes may provide an effective platform for anticancer drugs delivery.

In this research, a direct, simple and ultrasensitive fiber optic particle plasmon resonance (FOPPR) biosensing platform for immunoglobulin G (IgG) detection was developed using a gold nanoparticle/graphene oxide (AuNP/GO) composite as signal amplification element. To obtain the best analytical performance of the sensor, experimental parameters including the surface concentration of GO on the AuNPs, formation time of the GO, the concentration of the anti-IgG and incubation time of anti-IgG were optimized. The calibration plots displayed a good linear relationship between the sensor response (Delta I/I-0) and the logarithm of the analyte concentrations over a linear range from 1.0 x 10(-10) to 1.0 x 10(-6) g/mL of IgG under the optimum conditions. A limit of detection (LOD) of 0.038 ng/mL for IgG was calculated from the standard calibration curve. The plot has a linear relationship (correlation coefficient, R = 0.9990). The analytical performance of present work’s biosensor was better than that of our previously reported mixed self-assembled monolayer of 11-mercaptoundecanoic acid/6-mercapto-1-hexanol (MUA/MCH = 1:4) method by about three orders of magnitude. The achieved good sensitivity may be attributed to the synergistic effect between GO and AuNPs in this study. In addition, GO could immobilize more antibodies due to the abundant carboxylic groups on its surface. Furthermore, we also demonstrated that the results from this sensor have good reproducibility, with coefficients of variation (CVs) < 8% for IgG. Therefore, the present strategy provides a novel and convenient method for chemical and biochemical quantification and determination.

Drugs, including small molecule anticancer drugs, have to be delivered and released into the cytoplasm or nucleus in order to elicit a therapeutic effect. In the present study, a novel corona core-shell nanoparticle was proposed for enhanced cellular uptake and light-responsive intracellular release. Light-responsive core-shell nanoparticles, i.e., gold nanoparticles-coated liposomes (CS), were prepared and further modified with hyaluronic acid (HA) (CCS). HA modification enhances the endocytosis of the nanoparticles by HA receptor-expressing cells, while the plasmonic properties of gold nanoparticles enable their light-triggered drug release. The results demonstrated that the uptake of CCS in HA receptor-expressing MDA-MB-231R cells was significantly enhanced compared with unmodified CS. Nanosecond pulsed laser irradiation (700 nm; 100 mJ/cm(2); 5 pulses) rapidly triggered the intracellular release of a fluorescent dye, 6-carboxyfluorescein (6-CF), from CCS and CS trapped in endolysosomes. The released 6-CF was evenly distributed throughout the entire cytosol and nucleus. Finally, the cytotoxicity of doxorubicin towards MDA-MB-231 cells was significantly increased by CCS delivery upon pulsed laser irradiation. In conclusion, with enhanced cellular uptake and light-triggered intracellular release, CCS significantly enhanced the therapeutic effects of doxorubicin, and may serve as a promising avenue for intracellular drug delivery.

Cell encapsulation within 3D hydrogels is an attractive approach to develop effective cell-based therapies. However, little is known about how cells respond to the dynamic microenvironment resulting from hydrogel gelation-based cell encapsulation. Here, a tunable biomimetic hydrogel system that possesses alterable gelation kinetics and biologically relevant matrix stiffness is developed to study 3D dynamic cellular responses during encapsulation. Hydrogels are synthesized by crosslinking thiolated hyaluronic acid and thiolated chondroitin sulfate with poly(ethylene glycol) diacrylate under cell-compatible conditions. Hydrogel properties are tailored by altering thiol substitution degrees of glycosaminoglycans or molecular weights of crosslinkers. Encapsulation of human mesenchymal stem cells through hydrogel gelation reveals high cell viability as well as a three-stage gelation-dependent cellular response in real-time focal adhesion kinase (FAK) phosphorylation in live single cells. Furthermore, stiffer hydrogels result in higher equilibrium FAK activity and enhanced actin protrusions. Our results demonstrate the promise of hydrogel-mediated cellular responses during cell encapsulation. (c) 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47212.
