1. A method for detecting the interaction of a biological binding pair, said method comprising:
- providing a sensor comprising a substrate coated with a free electron metal, a matrix layer disposed on said free electron metal, said matrix layer comprising an organic compound, wherein said organic compound has a boronic acid complexing moiety and, a boronic acid moiety complexed to said boronic acid complexing moiety, wherein said boronic acid moiety is conjugated to a first member of said biological binding pair;
contacting said sensor with a second member of said binding pair, under conditions allowing binding of said second member to said first member of said binding pair, wherein the binding of said second member to said first member elicits a detectable response; and
measuring said response, thereby detecting said interaction of said biological binding pair.
