Abstract
Some embodiments of the invention include a synthetic biocidal surface comprising an array of disordered nanospikes. The biocidal surface may be lethal to cells on said surface due to piercing of cell membranes by said nanospikes. Some embodiments may include a method of producing a synthetic biocidal surface comprising an array of disordered nanospikes that may include exposing a silicon comprising substrate surface to reactive-ion etching.
Claims25
A synthetic biocidal surface comprising an array of disordered nanospikes that are lethal to cells on said surface, wherein said nanospikes are from 20 nm to 150 nm in diameter at half maximum height.
