Abstract:Cyanoacrylate nanoparticles have been studied in great detail over the past three decades with a view to their use as controlled release drug delivery materials. The mechanism of polymerization is anionic where the initiating species is the hydroxyl anion that was derived from dissociation of water. In the current research, amine groups on the surface of protein molecules (an animal protein, bovine serum albumin and a cereal protein, gliadin) are utilized as initiator for the polymerization. The resultant copolymer is amphiphilic in nature, and forms stable nanoparticle suspension. The suspension containing these nanoparticles showed an excellent coating capability on the surface of hydrophobic materials. A simple spray coating changed the wetting property of the material instantly and dramatically. When the coating was applied to solid surfaces like glass, it spread out, preventing the beading of water. Near-term application includes solar panels and side-windows on vehicles which have no wipers. This technology, applicable to the manufacturing of glass-window cleaners, is expected to show superiority over current, commercially available cleaners. Since both protein and poly(ethyl cyanoacrylate) are degradable polymers, the developed nanoparticles are degradable.
