Abstract :
This paper presents a novel technique for bacteria detection. The proposed system uses MC-1 magnetotactic bacteria and measures impedance to detect the presence of pathogenic bacteria. An electrode array is connected to respective cells that are fully integrated for impedance detection. The simulated performance shows that the circuit that was designed is robust. It can detect impedances ranging from about 3 KOmega to at least 100 MOmega. The only limits that we have for detecting large impedances are the operation frequencies and leakage currents. The circuit is thus very robust and can adapt to a wide range of uncertainty.
