Atmospheric Plasma‐Assisted Deposition and Patterning of Natural Polymers

Plasma-assisted deposition is a facile, yet sophisticated method to form biocompatible coatings on materials and introduce specific surface interactions. The plasma process provides unique features such as activation, functionalization, assisted polymerization, all of which can be obtained under low power room temperature conditions. further provide with enhanced adhesion stability. Here, it reported for the first time, controlled versatile biomaterial chitosan range substrates – soda-lime glass, metal alloy (Ti4Al6V), thermoplastic polymer (polyethylene terephthalate), silicone rubber (poly(dimethylsiloxane)). deposited films are characterized by atomic force microscopy, scanning electron microscopy Fourier transform infrared spectroscopy, evaluated proposed also successfully optimized multiple layers different biomaterials. Specifically, comprising alternate silk fibroin realized, together patterned surfaces programmable composition. biological response chitosan-on-fibroin fibroin-on-chitosan without patterning investigated using cell culture experiments. Selective area enables development improved finishes biomedical devices.
