Abstract

See full text

Nanoparticles which are comprised of a protein-poly(alkyl-cyanoacrylate) or protein-poly(alkenyl-cyanoacrylate) copolymer may be used as a surface treatment to alter the wetting properties of a variety of different materials. The nanoparticles are produced by the method comprising:

    a) providing a solution of a protein in an aqueous organic solvent mixture such as an acidified aqueous alcohol;b) adding an alkyl- or alkenyl-cyanoacrylate and mixing under conditions effective to react with the protein and produce the nanoparticles comprised of a protein-poly(alkyl-cyanoacrylate) or protein-poly(alkenyl-cyanoacrylate) copolymer; andc) recovering the nanoparticles.The nanoparticles are amphiphilic, and may alter the surface-wetting properties of an object when applied onto the surface thereof. When applied onto hydrophobic surfaces, the nanoparticles render the surfaces hydrophilic.
