Abstract
A review. Research is turning toward nanotechnol. for solns. to current limitations in
biomedical imaging and anal. detection applications. New to fluorescent nanomaterials that could
help advance such applications are protein-stabilized gold nanoclusters. They are potential
candidates for imaging agents and sensitive fluorescence sensors because of their biocompatibility
and intense photoluminescence. This review discusses the strategy for synthesizing fluorescent
protein-gold nanoclusters and the characterization methods employed to study these systems. Optical
properties and relevant light-emitting applications are reported to present the versatility of
protein-gold nanoclusters. These new bio-nano hybrids are an exciting new system that remains to be
explored in many aspects, esp. regarding the detn. of gold nanocluster local structure and the
enhancement of quantum yields. Understanding how to finely tune the optical properties will be
pivotal for improving fluorescence imaging and other nanocluster applications. There is a promising
future for fluorescent protein-gold nanoclusters as long as research continues to uncover
fundamental structure-property relationships.
