  • Slide 4 - Biopolymer-based BioMEMS BioMEMS refers to the application of microelectromechanical systems (MEMS) to biology. Current bioMEMS devices are either semiconductor-based or polymer-based, mostly PDMS. A biopolymer-based bioMEMS devices are created when chitosan is enlisted. The unique properties of aminopolysaccharide chitosan confer the bioMEMS device with special advantages such as reusability and low average-use cost.
