Pizeozelectric cell-based sensor was used to study cells or special materials. Plentiful information including growth and metabolism of cells, as well as responses to effects of complex and toxic materials can be obtained synchronously by the technology. Because of advantages in detection strategies such as being label-free, real-time, in-situ and non-invasive, this new analytical tecnology has been used widely in clinical diagnostics, environmental monitoring and food safety. Cell viscoelasticit...
