Wageningen University has developed a gel derived from proteins from the yeast Pichia pastoris. The gel, when used, slowly dissolves and passes the proteins inside to the outer environment.
Researchers Frits de Wolf and Marc Werten from Food & Biobased Research designed these protein molecules, which collectively form a network and swell in water. Each molecule consists of two small end pieces and a large middle piece, all of which can be custom designed. The molecule's short ends bond with the other molecules to form a network. The resulting gel can enclose other molecules, such as medicines or antibodies, proteins that are used by the human body to eliminate viruses and bacteria. Pieces of protein can also be built into the gel molecules themselves.
