Novel amino acid based nanogel conjugated suture for antibacterial application.

In this study, a promising preparation strategy for antibacterial silk sutures with an l-lysine based nanogel grafting is reported. The triclosan-loaded nanogels (NGTLs) were fabricated by the convenient enzymatic degradation of macrogels, namely, triclosan-loaded macrogel, degrading into NGTLs triggered by the trypsin. Nanogels, about 60 nm and 90 nm in diameter, were obtained after 7 days of biodegradation in the enzyme solution.

A rapid ammonia sensor based on lysine nanogel-sensitized PANI/PAN nanofibers.

In this paper, l-lysine-based materials which are rich in amino groups were synthesized through a chemical reaction. The polyaniline/polyacrylonitrile (PANI/PAN) thin film and PANI/PAN nanocomposite (NC) thin films doped with l-lysine based materials were obtained by electrospinning and in situ polymerization of aniline. The gas sensing properties of the PANI/PAN thin film and PANI/PAN NC thin films doped with l-lysine based materials towards NH, ethanol, acetone, chloroform and DMF were examined at room temperature.
