CHAPTER 1. The Design and Fabrication of Disposable Sensors: an Overview

This chapter starts with a brief introduction about biosensors, their basic characteristics and differentiates the term biosensors from sensors. Further, it focuses on electrochemical biosensors, the type of sensors and provides the theoretical background, working principles, types and advantages, role of macro and disposable electrodes in biosensors and their modification. Applications of disposable electrodes in various fields, including healthcare, agriculture, environment are discussed. The necessity of the detection of the analytes and the consequences of their presence in excess/absence in living systems and in the environment is also discussed.
