Abstract
With recent advances in novel nanomaterial development, electroanalytical biosensors are undergoing a paradigm shift. New nanomaterial-based electrochemical biosensors can detect specific biomolecules at previously unattainable ultra-low concentrations. This chapter lists the existing biosensor technologies, describes the mechanisms, and applications of two types of electroanalytical biosensors, and then identifies the barriers in developing these biosensors and concludes by illustrating how nanomaterials can help overcome these limitations. A key feature of the electrochemical impedance sensor is that biomolecules detection can occur in real time without any pre-labeling. Specifically, this chapter summarizes the state of knowledge of the impedance sensor as applied in cancer and bone disease studies, which are clinically relevant.
