Abstract

A novel enzyme-linked immunoassay with nanoparticle assemblies as optical probes is presented. The macrocycle cucurbit[7]uril assembles gold nanoparticles, and the enzymatic generation of ammonium by urease as the label of the immunoassay disperses the probes to yield variations of plasmon absorbance that are proportional to the target protein concentration.
