Abstract
Nanomaterials, the building blocks of nanotechnology, possess important physical properties such as particle aggregation, photoemission, electrical and heat conductivities, and chemical properties like catalytic activities. On the basis of such unique properties, nanomaterials have received much attention from scientists and researchers in different areas of biomedical sciences such as biomolecule detection, sensing applications, gene delivery, clinical diagnostics, etc. This review focuses on different types of nanomaterials including their synthesis, properties, conjugation with biomolecules, and their biosensing applications.
