Abstract

One kind of nanocarrier with distinctive optical characteristics and exceptional biocompatibility is gold nanoparticles (AuNPs). They are widely used in tissue engineering, diagnostics, and therapy, among other areas of biomedical engineering and medicine. With their distinct physicochemical characteristics, AuNPs are among the most stable metal nanoparticles and are a strong contender for a variety of biological applications. Biological synthesis techniques are preferred over other synthesis methods because they minimize the requirement for hazardous chemicals in the reduction process. Using a variety of materials, surface functionalization gives gold nanoparticles colloidal stability. The biological uses of AuNPs, including bioimaging, biosensing, drug transport, anticancer therapy, hyperthermia, and antibacterial activity, are the primary emphasis of this review. The optical characteristics associated with surface plasmon resonance (SPR) are utilized in biosensing.
