Advancements in Biosensing Technologies for the Detection of Human Immunodeficiency Virus

HIV (Human Immunodeficiency Virus) is one of the major health concerns and continues to be an epidemic causing threat to a large population of the world.Despite great efforts and strategies being employed for containing its spread, it still is hard to tackle in resource-limited settings.Conventional molecular detection methods are laborious and require trained staff and well-equipped laboratory facilities.In this review we have discussed biosensors for rapid, portable and highly sensitive point-of-care detection providing timely diagnosis and monitoring of infectious agents like HIV.Different types of biosensors for the detection of HIV have been developed over the last twenty years including Electrochemical, Optical and Piezoelectric biosensors.Although biosensors provide various advantages over standard diagnostic methods still there are technical limitations that need to be addressed for their commercial implementation.
