BPD can be used as a SAM that forms a sulfur functionalized layer on the gold surface for the formation of biocompatible interfaces for the immobilization of cells and proteins. It can prepare organic-metal-organic heterostructures using silver atoms which can be coated on the gold substrate for applications which include molecular electronics and plasmonics.
5,5′-Bis(mercaptomethyl)-2,2′-bipyridine (BPD) is an organothiol that forms a self-assembled monolayer (SAM) on a variety of surfaces such as metals and metal oxides.
