▎ 摘　　要

NOVELTY - Electrical cell-substrate impedance measurement system comprises well formed on a substrate in which cells (5) are in contact with a cell measurement area, and reduced graphene oxide and metal nanoparticles are formed in the well. An electric cell-substrate impedance sensing (ECIS) sensor is used for measuring cell-substrate impedance by depositing gold nanoparticles (15). A processor unit (3) is used for receiving a response signal generated from the ECIS sensor (1) in analog form, and digitally analyzing amplitude and phase characteristics for measuring impedance of cells from the response signal. The ECIS sensor has an average diameter of deposited AuNP of 10-20 nm. A DAQ board (30) converts the response signal into a digital signal and transmits the converted signal to a signal processing unit below. A signal processor for digitally receiving response signal from the DAQ board and analyzing amplitude and phase characteristics. USE - The electrical cell-substrate impedance measurement system is useful for measuring electrical properties of cells (claimed). ADVANTAGE - The system is economical and is suitable for portability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the electrical cell-substrate impedance measurement system (Drawing includes non-English language text).
