Abstract

Nanotechnology has revolutionized the field of biosensors, enabling early disease diagnosis and personalized healthcare monitoring. Utilizing the special qualities of nanomaterials, such as their high surface-to-volume ratio, remarkable electrical and optical capabilities, and customized surface chemistry, nanotechnology-enabled biosensors have created extremely sensitive and focused diagnostic instruments. With previously unknown sensitivity and accuracy, these biosensors can identify and measure a wide range of biomarkers, such as proteins, nucleic acids, and small molecules. This paper provides a comprehensive review of the latest advancements in nanotechnology-enabled biosensors, their working principles, fabrication techniques, and their applications in early disease diagnosis and personalized healthcare monitoring. It also addresses the difficulties and potential developments in this rapidly developing industry.

Keyworde: Nanotechnology, biosensors, early disease diagnosis, personalized healthcare monitoring, nanomaterials, biomarkers, sensitivity, selectivity
