Abstract

Endocytosis is a process in which a substance gains entry into a cell without passing through the cell membrane. This process is subdivided into three different types, receptor mediated endocytosis, pinocytosis and phagocytosis. In this study, we developed a capacitance sensor to monitor endocytosis in real time. During the receptor mediated endocytosis, a capacitance peak was observed. In contrast, the capacitance declined without a capacitance peak when nanoparticles or bacteria were taken up via non-specific pinocytosis or phagotytosis. In addition, we have developed a capacitance sensor array to demonstrate capacitance-based high-throughput screening. These results demonstrated that three types of endocytosis are able to be differentiated using our capacitance sensor.
