摘要

The maintenance of cell volume is critical to health. Cell volume change reflects many biological and physicological processes. We have developed a lab-chip to measure cell volume change in real-time with high sensitivity and resolution, and applicable to both adherent and suspended cell populations. The volume change was detected by measuring the impedance of extra-cellular solution within a microfluidic chamber containing the cells. Using microfabrication to make precise chamber dimensions, volume change can be detected in response to an osmotic gradient.
