Preparation of conductive self-healing hydrogels an interpenetrating polymer network method.

Conductive self-healing hydrogels and related soft sensor devices are gaining extensive attention from academia to industry because of their impacts on the lifetime and ergonomic design of artificial skins and soft robotics, as well as health monitoring systems. However, so far the development of such a material has been limited considering performance and availability. In this work, we developed composite hydrogels of acrylamide, polyacrylamide, dialdehyde-functionalized poly(ethylene glycol) and conductive carbon black through an interpenetrating polymer network strategy.

Antimicrobial peptide m2163 or m2386 identified from Lactobacillus casei ATCC 334 can trigger apoptosis in the human colorectal cancer cell line SW480.

Ribosomal synthesized antimicrobial peptides (AMPs) are widely distributed in nature and are toxic to certain microorganisms. Some of these AMPs are found to exhibit cytotoxic activity against the growth of cancer cells and thus have obvious anticancer potential. Here, we have studied the antiproliferation on the human colorectal cancer cell line SW480 of two AMPs, namely m2163 and m2386, identified by us from a lactic acid bacterium Lactobacillus casei ATCC 334 previously.
