This paper describes a novel photolithographic method to fabricate MEMS structures from chitosan, which is a beta-1,4-linked polysaccharide. The biopolymer chitosan is the partially deacetylated product of chitin. Chitin is used in nature as robust bioscaffolds and infrared absorbers. Chitosan has been shown to have similar properties and may additionally form cationic hydrogels. Patterning methods for chitosan in the literature include imprinting, electrodeposition, and mold-casting. These… CONTINUE READING
