Precise size-control and functionalization of gold nanoparticles synthesized by plasma-liquid interactions: using carboxylic, amino, and thiol ligands.

Using gold nanoparticles (GNPs) in high-standard applications requires GNPs to be fabricated with high-quality size and surface properties. Plasma-liquid interactions (PLIs) have the unique ability to synthesize GNPs without using any reducing agents, and the GNP surface is free of stabilizing agents. It is an extreme advantage that ensures success for the subsequent functionalization processes for GNPs.

Optimization and characterization of electrospun polycaprolactone coated with gelatin-silver nanoparticles for wound healing application.

Bacterial infection and damage caused by dressing removal are two concerning problems which prolong the healing process in treatment of skin injuries. In this study, plasma treated electrospun polycaprolactone (PCL) scaffold was coated with silver nanoparticles (AgNPs) embedded in gelatin (Gel) by multi-immersion technique to optimize its antibacterial performance and reduce wound-scaffold adhesion. Water interaction test was used to examine the hydrophilization of PCL electrospun fibers after plasma treatment.
