Self-Regulated Bio-Nanostructured Membranes for MEMS

This paper describes a novel self-regulated bio-nanostructured membrane designed for MEMS. The membrane has a unique, rigid three-dimensional nanostructure with nano-pores that are formed by the motions of bacteria. The properties of this material and its suitability for sorting or filtration systems were evaluated. Since the self-regulated bio-nanostructured membrane is consisting of ultrafine rigid fibrils, and scale of which is 100 to 1000-fold smaller than conventional fibers, the membrane resisted up to 2 MPa of pressure without any clogging, whereas conventional membrane withstood less than 0.5 MPa.
