Development of the Mobile PoC Graphene-Based Biosensing Device Using Electrochemical Impedance Spectroscopy (EIS)
In the paper the results of research on a multifunctional graphene-based biosensor are presented.
Project of a mobile device is described for Point-of-Care (PoC) diagnostic tests based on Electrochemical Impedance Spectroscopy (EIS) and Bioelectrical Impedance (BI) technique, using integrated impedance scanner AD5933 (Analog Devices). Design of a biosensing electrode, a control circuit based on XMEGA microprocessor, and results of preliminary experiments and simulations are also presented.
