Abstract:
1. An apparatus for detecting the presence of a target molecule comprising: a conductive nanostructure; a non-conductive polymer coating on at least a portion of the nanostructure, the non-conductive polymer coating defining a cavity having a shape corresponding to the shape of the target molecule wherein the thickness of at least a portion of the non-conductive polymer coating is less than or about equal to the size of the cavity; and a detection unit configured to produce a signal indicative of the presence of the target molecule at the cavity based on a measured change in a property of the nanostructure, wherein the property of the nanostructure depends on the binding of the target molecule with the non-conductive polymer coating at the cavity, and wherein the polymer coating is self-limiting under electro polymerization and comprises a polyphenol film.
