Definition

Biosensors are analytical devices incorporating biological or biologically derived sensing elements with physicochemical transducers to produce digital electronic signals [1]. These biosensors determine the concentration of substances and other parameters of biological interest. The detecting elements of biosensors work in different physicochemical ways: optical, piezoelectric, electrochemical, thermometric, and magnetic. Biosensors using magnetics utilize the magnetic field created by magnetic particles that bind to target molecules in a biological assay (Fig. 1).
