A new method of supramolecular emulsion interfacial polymerization is developed, which can be used to fabricate supramolecular polymeric nanospheres. We designed a water-soluble monomer containing two maleimide end groups, acting as both building block and surfactant, and an oil-soluble supramonomer bearing two thiol groups connected by quadruple hydrogen bonds. With the assist of ultrasonication, hollow nanospheres can be controllably prepared by thiol-maleimide reaction of two monomers at the emulsion interface, which exhibit good stability and dynamic property. In addition, the encapsulated guest molecules could be controllably released from the supramolecular polymeric nanospheres, owing to their stimuli-responsiveness. It is anticipated that this approach will enrich the methodology of supramolecular polymerization and can be applied to constructing supramolecular materials with controllable structures and functions.

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.

Polymers of intrinsic microporosity (PIMs) are a class of microporous polymers with rigid and contorted molecular structures. The special structures lead to incomplete space occupation, and the pores of PIMs originate from the formed void. In this work, we made attempts to expand the applications of PIMs to the aspect of heavy metal removal. First, PIM-1 was synthesized using tetrafluoroterephthalonitrile (TFTPN) and 5,5′,6,6′-tetrahydroxy-3,3,3′,3′-tetramethyl-1,1′-spirobisindane (TTSBI) as precursors. The primary PIM-1 was quite hydrophobic, and thus could not be evenly dispersed in water, resulting in low adsorption capacity for mercury ions (Hg2+). A conversion of nitrile group in PIM-1 to thiol group was then carried out by two steps, namely carboxylation and introduction of thiol groups. The carboxylation made the polymers more active, and the final thiol-functionalization provided the polymers with hydrophilicity and affinity for Hg2+. The thiolethyl modified PIM-1 (assigned as PIM-G) and thiophenyl modified (assigned as PIM-B) possessed maximum Hg2+ adsorption capacity of 136 mg g(-1) and 127 mg g(-1) at pH 5, respectively. Besides, the thiol-functionalized PIMs had fluorescence property and showed potential in sensing for Hg2+.

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. Recommanded Product: 56-17-7.

In this work, a facile click reaction strategy is employed to form hydrogels in situ with cytocompatibility, biodegradability, self-healing property and resistance to protein. The thiol-functionalized zwitterionic carboxybetaine methacrylate copolymer, which take part as a cross-linker in the thiol-ene click reaction with the methacrylated hyaluronic acid. The hydrogels are obtained under the physiological condition without the presence of any copper catalyst and UV light. The hydrogel consisting of zwitterionic component shows an obvious reduction in protein adsorption and cell adhesion and avoid non-targeted factor interference in the biological experiments. The hydrogels also demonstrate adjustable degradation behavior. Human mesenchymal stem cells (hMSCs) are easily encapsulated into the hydrogels and remains metabolically active, indicating the excellent biocompatibility of the hydrogels. Additionally, the result of the cytokine secretion assays (IL-6 and TNF-alpha) has shown that this clickable hydrogel can serve to suppress inflammatory reactions and is beneficial for in vivo applications. Based on the above results, this clickable hydrogel with excellent performance can be an amenable platform for 3D cell encapsulation.

Molecular machines are ubiquitous in nature and function away from equilibrium by consuming fuels to produce appropriate work. Chemists have recently excelled at mimicking the fantastic job performed by natural molecular machines with synthetic systems soluble in organic solvents. In efforts toward analogous systems working in water, we show that guest molecules can be exchanged in the synthetic macrocycle cucurbit[7]uril by involving kinetic traps, and in such a way as modulating energy wells and kinetic barriers using pH, light, and redox stimuli. Ditolyl-viologen can also be exchanged using the best kinetic trap and interfaced with alginate, thus affording pH-responsive blue, fluorescent hydrogels. With tunable rate and binding constants toward relevant guests, cucurbiturils may become excellent ring molecules for the construction of advanced molecular machines working in water.

Recent advances in the development of protein-based vaccines have expanded the opportunities for preventing and treating both infectious diseases as well as cancer. However, the development of readily and efficient antigen delivery systems capable of stimulating strong cytotoxic T-lymphocyte (CTL) responses remains a challenge. With the attempt to closely mimic the properties of viruses in terms of their size and molecular organization, we constructed RNA (which is a ligand for Toll-like receptor 7 (TLR7) and TLR8) and antigen-loaded nanoparticles resembling the structural organization of viruses. Cationic polymers containing either azide or bicyclo[6.1.0]nonyne (BCN) groups were synthesized as electrostatic glue that binds negatively charged single stranded RNA (PolyU) to form a self-crosslinked polyplex core. An azide-modified model antigen (ovalbumin, OVA) and a BCN-modified mannosylated or galactosylated polymer were sequentially conjugated to the RNA core via disulfide bonds using copper free click chemistry to form the shell of the polyplexes. The generated reducible virus mimicking particles (VMPs) with a diameter of 200 nm and negatively surface charge (-14 mV) were colloidally stable in physiological conditions. The immunogenicity of these VMP vaccines was evaluated both in vitro and in vivo. The surface mannosylated VMPs (VMP-Man) showed 5 times higher cellular uptake by bone marrow derived DCs (BMDCs) compared to galactosylated VMP (VMP-Gal) counterpart. Moreover, VMP-Man efficiently activated DCs and greatly facilitated MHC I Ag presentation in vitro. Vaccination of mice with VMP-Man elicited strong OVA-specific CTL responses as well as humoral immune responses. These results demonstrate that the modular core-shell polymeric nanoparticles described in this paper are superior in inducing strong and durable immune responses compared to adjuvanted protein subunit vaccines and offer therefore a flexible platform for personalized vaccines.

RNA interference (RNAi) is an emerging therapeutic modality for tumors. However, lack of a safe and efficient small interfering RNA (siRNA) delivery system limits its clinical application. Here, we report a bioreducible and less-cationic siRNA delivery carrier by conjugating Zn(II)-dipicolylamine complexes (Zn-DPA) onto hyaluronic acid (HA) via a redox-sensitive disulfide (-SS-) linker. Such polymer conjugates can formulate stable siRNA nanomedicines via coordination between zinc ions of DPA and the anionic phosphate of siRNA. After the conjugates are taken up by cells, intracellular reduction stimulus subsequently triggers the release of siRNAs and elucidates the desired RNAi effect. Our studies showed the formulated siRNA nanomedicines can be efficiently delivered into tumor cells/tissues and mediates less cytotoxicities both in vitro and in vivo. More importantly, when applied in a xenograft glioblastoma tumor model, this siRNA nanomedicine demonstrated significantly enhanced antitumor ability comparing to naked siRNA. This work demonstrates that such bioreducible Zn-DPA-functionalized HA conjugates without using cationic material as a siRNA carrier represents a promising direction for RNAi-based cancer therapy.

A triply responsive amphiphilic polymer containing poly (ethylene glycol) (PEG) and pyrene linked by a disulfide bond (PEO-SS-PY) was synthesized. Benefiting from its amphiphilicity, PEO-SS-PY could self-assemble into 126 nm micelles in water. PEO-SS-PY with CB[7] forms a 1:1 pseudorotaxane polymer (PEO-SS-Py@CB[7]) in aqueous solution. After the formation of host-guest complex, the micelles size increased to 136 nm and the fluorescence emission intensity increased. Glutathione would break the disulfide bond, leading to the dissociation of the micelles. Spermine and adamantanamine hydrochloride would dissociate the host-guest complex, leading to change of micelle size and decrease of fluorescence intensity. More interestingly, this self-assembly micelle displayed highly sensitive response to Fe3+. Because the effective absorption of Fe3+ hindered the absorption of PEO-SS-Py@CB[7] at the excitation wavelength of 405 nm, Fe3+ distinctly quenched the fluorescence emission of PEO-SS-Py@CB[7], whereas, a very low changes of intensity was observed for other metal ions. Results of this paper provide a new idea for the combination of metal ion detection and controlled release.
