Abstract:

In the past few decades,gold and silver nanoclusters(Au NCs and Ag NCs)have been extensively explored and used in industrial catalysis,optoelectronic devices,biological imaging,environmental testing,clinical diagnosis and treatment. However,as precious metal clusters,there is relatively little discussion about the biosensing application of platinum nanoclusters(Pt NCs). Pt NCs are of excellent reactivity,optical properties,catalytic activity,electrical conductivity and biocompatibility,and has been proven to be used in biosensing and medical imaging. In view of the above-mentioned excellent performance,we summarized Pt NCs from the perspective of synthesis and unique properties,and outlined their biological applications in sensing and imaging.

Key words: platinum nanoclusters, fluorescence, catalysis, biosensors
