Identification of blood cell types using magnetostrictive-microcantilever-based biosensors

High sensitivity and high Q value, as well as working well in liquid, make the newly developed magnetostrictive microcantilevers (MSMCs) a great candidate for developing a high performance biosensor. In this paper, blood cell identification by the MSMCs was demonstrated. The MSMCs were fabricated and their surface was functionalized by immobilizing anti-B antibody as the bioreceptor for blood cells inspection. By immersing the MSMCs into different type blood cells and monitoring the resonance frequency shift, due to blood cell binding, the blood cells A and B were distinguished.
