Gold Nanoparticles are the most extensively  nanomaterials for biomedical application due to their unique properties, such as rapid and simple synthesis, large surface area, strong adsorption ability and facile conjugation to various biomolecules. The remarkable photophysical properties of gold nanoparticles have provided plenty of opportunities for the preparation of gold nanoparticles-based optical biosensors, while the excellent biocompatibility, conductivity, catalytic properties and large surface-to-volume ratio have facilitated the application of gold nanoparticles in the construction of electrochemical biosensors.

The unique properties of Gold Nanoparticles have stimulated the increasing interest in the application of GNPs in interfacing biological recognition events with signal transduction and in designing biosensing devices exhibiting novel functions. The optical properties of GNPs provide wide range opportunities for construction optical biosensors. The excellent biocompatibility, conductivity, catalytic properties and high surface-to-volume ratio and high density of GNPs facilitate extensive application of GNPs in construction of electrochemical and piezoelectric biosensors with enhanced analytical performance with respect to other biosensor designs. GNP-based optical, electrochemical and piezoelectric biosensors.

Gold Nanoparticles-based piezoelectric biosensors:  Piezoelectric biosensors measure the mass change arising from the biological recognition process. Gold Nanoparticles-based piezoelectric biosensors, the mechanisms of the sensitivity enhancement contribution of Gold Nanoparticles can be summarized as follows: Surface enhancement effect and mass enhancement effect. A piezoelectric sensor is mass-sensitive device, which means any strategies that amplify the mass change will improve the analytical sensitivity. The quantity and activity of biological recognition elements immobilized on the sensing surface of piezoelectric biosensors determines sensitivity as well as the regeneration ability. The high surface area-to-volume ratio and biocompatibility of Gold Nanoparticles, which provide a very large number of interaction sites, make GNPs po

Optical biosensors generally measure changes in light or photon output. For optical biosensing utilizing Gold Nanoparticles, the optical properties provide a wide range of opportunities, all of which ultimately arise from the collective oscillations of conduction band electrons plasmons in response to external electromagnetic radiation. There are several optical sensing modalities for Gold Nanoparticles, and the surface plasmon resonance (SPR). SPR  is an optical phenomenon arising from the interaction between an electromagnetic wave and the conduction electrons in a metal, is used for probing and characterizing physicochemical changes of thin films on metal surface .
