Sensing applications of micro- and nanoelectromechanical resonators

The sensitivity of micro- and nanoscale resonator beams for sensing applications in ambient conditions was investigated. Micro-electromechanical (MEMS) and nanoelectromechanical systems (NEMS) were realized using silicon carbide (SiC) and polycrystalline aluminium nitride (AlN) as active layers on silicon...

AlGaN/GaN sensors for direct monitoring of fluids and bioreactions

AlGaN/GaN based pH-sensors have been characterized and further developed for the in situ monitoring of cell reactions. Generally, good proliferation of different cell lines was observed on AlGaN and GaN surfaces without using any kind of thin films of organic material for improving of the cellular adhesion...
