Electrochemical Detection of Sequence-Specific DNA with the Amplification of Gold Nanoparticles
A sensitive electrochemical DNA biosensor was prepared based on mercaptoacetic acid (MAA)/gold nanoparticles (AuNPs) modified electrode. Probe DNA (NH2-DNA) was covalently linked to the carboxyl group of MAA in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) and N-...
