Detection of HIV virus using biosensor

Development of more reliable methods for the detection and quantification of HIV is of great interest and worth. In comparison to the gold standard technique including ELISA, western blot assay, and nucleic acid hybridization strategies, the biosensor-based techniques can potentially be more efficient, reliable, and sensitive for the detection of HIV. Using the biosensors, viral detection along its components has been shown to be far better in many ways as the gold standard methods used for the virus detection are costly, laborious, and less efficient. The electrochemical biosensors are potentially faster, cheaper, and easy-to-use and are much required for point-of-care or self-testing. Furthermore, nanotechnology has revolutionized the area, and efforts are being made for the development of miniaturized and efficient designs for the electrochemical biosensors with more sensitivity and selectivity. In this chapter, some recent developments in the detection of HIV infection with nanobiosensors, especially the electrochemical ones, are reviewed.
