Abstract:
1. A method of depositing a film on a biological substrate, comprising: placing a dielectric conduit in the proximity of the biological substrate, the dielectric conduit having a high voltage electrode disposed about its external surface; directing a gas flow containing a precursor material through the interior of the dielectric conduit; supplying the high voltage electrode with an alternating voltage, wherein an electric field generated by a potential difference between the high voltage electrode and the biological substrate ionizes at least a portion of the gas flow causing a plasma to emanate from a downstream end of the dielectric conduit, propagate through ambient conditions, and contact the biological substrate, and wherein the plasma induces a polymerization reaction of the precursor material to form a film that is deposited on the biological substrate.
