【英文摘要】
By acquiring and analying the response information from cells, the piezoelectric cell-based sensor chip (PCSC) 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 substance 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 is most promisingly applica...
