Appl. No.:

13/295059

Inventors:

V. Prasad Shastri - Nashville TN, US
Thomas Soike - Johnson City TN, US
Chenxia Guan - Nashville TN, US

International Classification:

A61F 2/82
B29C 67/00
B05D 5/00

US Classification:

623 146, 427 225, 264491

Abstract:

In one aspect, the invention relates to coated substrates comprising a substrate having a surface, a cationic polymer layer adjacent the surface of the substrate, an anionic polymer layer adjacent the cationic polymer layer and methods for producing and using same. In one aspect, the cationic polymer layer comprises at least one residue of a first compound having the structure:In a further aspect, the anionic polymer layer comprises at least one residue of a compound having the structure:In a yet further aspect, at least one nanoparticle or microparticle is positioned within one or both of the anionic polymer layer and the cationic polymer layer. In a still further aspect, the outermost polymer layer has a surface having fractal characteristics. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
