Au-nanoparticles as an electrochemical sensing platform for aptamer-thrombin interaction.


A novel electrochemical method for the detection of bioaffinity interactions based on a gold-nanoparticles sensing platform and on the usage of stripping voltammetry technique was developed. The oxidation of gold surface (resulted in gold oxide formation) upon polarization served as a basis for analytical response. As a model, thrombin-thrombin binding… (More)
