| Summary: | High sensitive and rapid detection of cancer cells is important to diagnosis and treatment of cancer. This study presented a portable micro-electrochemical system for detection of cancer cells by measuring electrochemical behaviors of molecule probe. The relevant hardware was divided into three parts, i.e., MCU circuit module, current measuring circuit module and potentiostatic circuit module. Information between modules exchanged through the system bus. The software was designed for generating and acquisition of signals, communication between master and slave, and data analysis. The performance of this portable micro-electrochemical system was validated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) of potassium hexacyanoferrate (III) solution at ITO electrode. Based on this portable instrumental system, a rapid detection of cancer cells was realized by using electrochemical probes. This puts forward to the portable micro-electrochemical system for rapid detection and diagnosis of cancers in clinical application.
