Abstract

Methods for forming useful films using recombinant spider silk protein are discussed. In one embodiment, the method involves dissolving silk protein in a sufficient quantity to form a film suspended in a solvent. The solution is then mixed with a compound selected from water, acids, imidazole crosslinking agents, antibiotics, nanoparticles, surfactants and combinations thereof. Solubilisation of the protein in the solution is effected by microwave exposure. Once solubilized the microwave treated solution is poured onto a suitable substrate and dried in order to result in the final film, the protein may be plant, mammal or bacterially derived. The film has widespread use and can be combined with any one of a number of substrates, examples of which include: a cosmetic composition; a pharmaceutical or medical composition, drug delivery system, artificial cell, contact lens coating, sustained-release drug delivery system, artificial skin graft; food composition; automotive part; aeronautic component; computer or data storage device, building material, textile, filter material, membrane material, nanomaterial, electronic component and combinations thereof.
