New bio-detection methods based on giant magnetoresistance (GMR) or tunneling magnetoresis-tance (TMR) sensors and magnetic nanoparticles are attracting much attention due to their high sensitivity and low cost. In literature, signal to noise ratio (SNR) is often used to estimate detection limit. However, because the actual bio-signal is obtained by differentiating signals before and after biological reactions, large temperature coefficient (>1000PPM/degC) of these devices can result into… CONTINUE READING
