Abstract

The bioelectrical characteristics of plant cells can motivate scientific and technological advancements, especially in synthetic biology. Until now, scientists have made many efforts to use plant-cells-on-chip (PCOC) devices to investigate how cells respond to external stimuli, including chemicals, mechanical forces, and electricity. In this paper, we present a PDMS and PCB-based EIS biosensor integrated fluidic platform to analyze the response of onion inner epidermal cell membranes when subjected to electrical signals at various frequencies by electrochemical impedance measurements. We also examined different scenarios, such as ion liquid stimulation, pH stimulation, and membrane size. Considering the onion inner membrane as a black box, we can further investigate the electrical characteristics of the onion cells and its potential as bioelectronics components. We demonstrated the measurement results in the …
