Arduino-based Nano-bioimedance Sensor System for Detection of Cancer Cells
Project Description

Cancer is one of the top killers in Hong Kong and the other world. Conventional cancer diagnostics using invasive biopsy and/or positron emission tomography in hospitals is expensive and time-consuming. Micro electrochemical biosensors are promising for point-of-care diagnosis of cancer, a leading cause of death worldwide. Cancer cells have different electrical properties, i.e. impedance, capacitance, etc., as compared to normal ones due to altered cell properties, i.e. different metabolism, distinct membrane permeability for Na/Ca/Mg ions, etc

This project is to design and fabricate a low-cost Arduino-based nanno-bioimpedance sensor system. The design and manufacturing of this prototype are challenging.
