| Abstract: | Aiming at response mechanism of specificity of static micro-cantilever surface, induce surface-stress signal,introduce working principles of bio/chemical micro-cantilever sensors, describe simplified model of stress response mechanism. Analyze change of surface-stress of cantilever caused by specific adsorption of vertical interface and lateral molecule interactions, discuss relationship between interfacial energy change, steric effect, electrostatic force, and hydrogen bonding and size and direction of surface stress, summarize response mechanism of stress type micro-cantilever bio/chemical sensor. |
