Abstract

This chapter reports a short review on electrochemical nanoengineered biosensors in infectious disease diagnosis. Early and timely diagnosis of infectious diseases has tremendous medical and social significance which advocates the development of new diagnostic tools. In this chapter, we discussed various electrochemical sensors for detection and diagnosis of tropical or subtropical fevers particularly dengue fever and malaria parasite. We also addressed the several important aspects of biosensors, namely, selectivity, sensitivity, and interference, and also the effect of engineering the nanomaterials (0D, 1D, 2D) on these aspects. In detail, we discussed the various techniques to immobilize the biomolecules on working electrode (glassy carbon, gold electrode, flexible substrates). Further, we discussed the several miniaturized sensing platforms with integrated microfluidic channels which can ensure for development of sensors for point-of-care applications.
