, p. 896 - 899 (2016)
We demonstrate here a strategy for enhanced antibacterial activity against microbial strains by the assembly of antimicrobial peptides with a temperature-responsive polymeric carrier. The assembly complex was less toxic to human cells and more stable to enzymatic cleavage. This work may provide a promising drug delivery system for antimicrobial peptides.
Controlled synthesis of photosensitive graft copolymers with high azobenzene-chromophore loading densities in the main and side chains by combining ATRP and ADMET polymerization
Ding, Liang,Li, Juan,Wang, Chengshuang,Lin, Ling
, p. 85 - 92 (2015)
Photosensitive graft copolymers containing azobenzene chromophores in the main and side chains were successfully synthesized by combining living atom transfer radical polymerization (ATRP) and acyclic diene metathesis (ADMET) chemistry based on the results of proper heterodifunctional inimer and azobenzene monomer design. The precise copolymer architectural features were manipulated by combining the macromonomer technique and the macroinitiator method. The as-prepared copolymer containing azobenzene chromophores in the main and side chains showed unique reversible isomerization processes, suggesting that the photoisomerization of azobenzene chromophores occured mainly in one of the two types of azobenzene groups in the main or side chains with similar probabilities due to their main and side-on structure.

POLYMER MATERIALS FOR DELIVERY OF SHORT-CHAIN FATTY ACIDS TO THE INTESTINE FOR APPLICATIONS IN HUMAN HEALTH AND TREATMENT OF DISEASE

Page/Page column 32, (2018/11/22)
Provided herein are polymer materials that find use in, for example, delivery of short-chain fatty acids. In particular, polymers are provided that form stable nanoscale structures and release their payload, for example, by cleavage of a covalent bond (e.g., via hydrolysis or enzymatic cleavage). The polymers are useful, for example, for delivery of payloads (e.g., SCFAs) to the intestine for applications in health and treatment of disease, and have broad applicability in diseases linked to changes in the human microbiota including inflammatory, autoimmune, allergic, metabolic, and central nervous system diseases, among others.
Solid-state, individual dispersion of single-walled carbon nanotubes in ionic liquid-derived polymers and its impact on thermoelectric properties

The structure of carbon nanotubes and their electronic interaction with a matrix are important for extracting the unprecedented electronic properties, which have yet to be explored. Here we investigate the dispersibility of single-walled carbon nanotubes (SWNTs) in ionic liquid-derived polymers (PILs), revealed by cross-sectional transmission electron microscopy, infrared optical spectroscopy, and Raman spectroscopy. Surprisingly, SWNTs studied here are highly dispersed, at least down to 7.5 nm-fibres, in a trimethylammonium-suspended PILs. Based on this discovery, we found that the well-dispersed and almost fully dispersed SWNTs in PILs are responsible for the enhanced thermoelectric properties, a future energy harvesting technique.
