Bio MEMS/NEMS

The Micro/NanoElectroMechanical Systems (MEMS/NEMS) need to be designed to perform expected functions typically in millisecond to picosecond range. Most mechanical properties are known to be scale dependent. For BioMEMS/BioNEMS, adhesion between biological molecular layers and the substrate, and friction and wear of biological layers can be important. Component-level studies are required to provide a better understanding of the tribological phenomena occurring in MEMS/NEMS. The emergence of the fields of nanotribology and nanomechanics, and atomic force microscopy (AFM) atomic force microscopy (AFM)-based techniques, has provided researchers with a viable approach to address these problems.
