Peptide Self-Assemblies for Detecting Ammonia and Urea Oxidation

What is it about?

This article reports on the development of a nonenzymatic biosensor for the detection of ammonia and urea oxidation on the basis of deposition of peptide microstructures onto thiolated gold electrodes.

Why is it important?

Our detection method of ammonia and urea oxidation is easy to follow, does not require a mediator or enzyme, and has strong potential for detecting urea via nonenzymatic routes.
