摘要：
A study was conducted to demonstrate the use of gold nanoparticles (AuNP) in chemical and biological sensing. AuNPs possessed distinct physical and chemical attributes that made them excellent scaffolds for the fabrication of novel chemical and biological sensors. AuNPs were synthesized in a straightforward manner and made highly stable, while possessing unique optoelectronic properties and providing high surface-to-volume ratio with excellent biocompatibility using appropriate ligands. These synthetic routes and properties of AuNPs made them excellent probes for different sensing strategies. A variety of other ligands had been used to passivate and functionalize AuNPs, while most AuNP functionalization had been done using thiol or thiolated ligands.
