Organic/inorganic hybrid nanostructures for biological imaging and delivery

Abstract

Nanostructures with their unique physicochemical properties have attracted extensive scientific attention and have been exploited till now for various biomedical applications. The applicability of nanomaterials in biology critically relies on both of its inorganic constituent core and organic surface functionality. Surface provides an effective way to control the interface of the nanomaterials with biological systems, whereas the inorganic core provides specific physical properties. This article briefly explains few inorganic hybrid nanoparticles majorly focusing on gold nanoparticles and reviewing its conventional way of synthesis, surface functionalization, characterization techniques, and physicochemical properties. At last, we have highlighted the recent applications of few inorganic nanoparticles as therapeutic delivery vehicles, and bioimaging agents.
