Competition assays are suitable for the detection of small molecules. In this detection scheme, the AuNPs-functionalized sensing surface is modified with target analytes. In a sensing event, a sample of free-flowing analytes are premixed with corresponding bioreceptors followed by introduction to the sensing surface. Free-flowing analytes and bound analytes then "compete" for binding with the bioreceptor. Binding of bioreceptor to the bound analyte results in an optical response. ...
