- 摘要：Materials contact with biological systems through their surfaces/interfaces; the interaction of material surfaces with the biomolecules and cells in the biological environment plays an important role to determine the realization of the biological functionalities of the materials. Therefore, the regulation of the interactions between the materials and the organism is the key issue in the research and application of biomaterials. In this review, we summarized the recent research progress of our group in the field of biointerfaces. Based on the design of biofunctional surfaces on the molecular level, we have established a series of facile modification methods with high efficiency and general applicability to change the physical and chemical properties of material surfaces, and thus to regulate the interactions of material surfaces with a variety of biological molecules(such as proteins)or cells/bacteria.关键词：Biomaterial surfaces/interfaces;Protein;Cell;Bacteria;Interaction

发布时间：2022-09-18 - 摘要：The hierarchical structure of polymers is notoriously difficult to control. Control over the hierarchical structures would, however, bridge the gap between structure, property of single chain and macroscopic structure, property of polymers. In this review, we summarized the recent research progress of our group in ferroelectric poly(vinylidene fluoride-trifluoroethylene). We have developed a simple nanoembossing protocol for simultaneously fabricating arrays of polymer nanostructures and controlling internal hierarchical structures. The application of the method to poly(vinylidene fluoride-trifluoroethylene)allows us to fabricate high-density arrays of ferroelectric nanostructures. The orientation of the polarization axis, about which the dipole moment rotates, is simultaneously aligned in plane over the whole patterned region. The improved crystal orientation translates to improved ferroelectric and piezoelectric properties such as lower coercive filed and higher pieozoelectric coefficient.关键词：Ferroelectric polymer;Hierarchical structures;Geometrical confinement;Orientation;Non-volatile memory

发布时间：2022-09-18 - 摘要：Biodegradable polymeric nanocarriers have emerged as one of the most promising platforms for targeted tumor therapy owing to their prolonged circulation time, enhanced accumulation in tumors, decreased adverse effects, improved drug bioavailability, and in vivo biodegradability. However, their therapeutic outcomes are far from optimal partially owing to inefficient and slow intracellular release of drugs at pathological sites. The development of stimuli-responsive nanocarriers that achieve fast drug release at the target site has received great interests. Notably, glutathione(GSH)concentration in tumor tissue and especially inside tumor cells varies from 2 to 10mM, which is about 100~1000 times higher than that in body fluids and extracellular matrices(2~10μM). Taking advantage of the high reducing potential, various reduction-sensitive polymeric nanocarriers have been fabricated for triggered anticancer drug release in tumor tissues and tumor cells. These reduction-sensitive nanocarriers have displayed several unique merits:(1)they have good stability under physiological conditions;(2)they show fast response to intracellular reducing environment, resulting in efficient intracellular drug release;(3)no extra instrument is required. This review highlights the construction and applications of various bioreducible biodegradable polymeric nanocarriers, including bioreducible biodegradable polymeric micelles, polymersomes, and nanogels.关键词：Reduction-sensitive;Polymeric micelles;Polymersomes;Nanogels;Reversible crosslinking;Targeted release;Tumor therapy

发布时间：2022-09-18 - 摘要：Hydrogen bond between molecules is a very important weak interaction. Hydrogen bonding has been applied to the controlled radical polymerization(CRP)system to achieve the dual control of molecular weight and stereoregularity, which makes the precision syntheses of polymers possible. However, the exact reason for the molecular weight control has not yet been realized. In the recent years, our group has focused on the hydrogen bonding induced controlled radical polymerization of methyl methacrylate, 4-vinyl-pyridine and 2-vinyl-pyridine. Control over molecular weight, tacticity and monomer sequence have been realized. Importantly, for the first time, the systematic research revealed that the hydrogen bonding can activate the monomer by electron induction interaction. The concept of hydrogen bonding promoting CRP or monomer-activating effect undoubtedly opened a new avenue to improve the controllability of those less active monomers.关键词：Hydrogen bonding interaction;Controlled radical polymerization;Stereoregularity;Sequence control

发布时间：2022-09-18 - 摘要：Sugars are the foundation of all life and play an irreplaceable role in a variety of cellular events. Glycopolymers with pendent sugar moieties, which are able to interact with lectin as multivalent ligand in a similar manner to natural glycoproteins, are relatively easy to synthesize and are attracting more attentions recently. Cell surface glycosylation is believed to be important in understanding and the treatment of cancer, and certain sugars have high affinity toward receptors or proteins on cancer cell surface. Herein reports especially those from our lab about the synthesis and application of glycopolymers with high affinity toward cancer cells are discussed, with special focus on the one-pot synthesis of glycopolymers and the application of glycopolymer-based materials as models to interact with protein/cells, in targeted cancer cell imaging/therapy and tumor cell capturing. It is demonstrated that efficient polymeric synthetic methods greatly simplify the fabrication of carbohydrate-based materials, and complex glycopolymer-based materials has a broad application prospects.关键词：Glycopolymer;One-pot;Click chemistry;Nanomaterials;Cancer cells

发布时间：2022-09-18 - 摘要：High refractive index polymers(HRIPs)have been widely utilized in optical and optoelectronic devices due to their advantages of light weight, flexibility, high impact strength and easy processing. The refractive indices of polymers mainly depend on their chemical structures. Introducing highly polarizable atoms or groups such as aromatic rings, sulfur-containing groups, halogens(except fluorine), organometallic moieties, and fullerenes into the polymers can efficiently enhance their refractive indices. Therefore, the refractive index value of a polymer can be tuned in the way of molecular tailoring, which provides good insight in developing new high refractive index polymers. This mini-review summarizes principles in molecular designing and recent progresses in high refractive index polymers.关键词：Refractive index;Polymers;Abbe number
