Abstract

original image

A novel superhydrophobic biodegradable coating with micro-/nanometer rough structure, fabricated by co-electrospraying poly(L-lactide) (PLLA) and modified silica nanoparticles (MSNs), exhibits good anti-adhesion behavior towards bacteria and cells in the initial culturing phase, which makes it a promising technology for preparing medical device coatings.
