Detect Ampicillin Accurately Using Novel Colorimetric Aptasensor
In this colorimetric aptasensor, two assay strategies including adsorbed thiolated aptamer(T-Apt)and adsorbed non-thiolated poly-Adenine aptamer(polyA Apt) on the gold nanoparticles (AuNPs) surfac were used for a simple, rapid and accurate determination of ampicilline(AMP). In this methods by incubating the AuNPs and the aptamer prior to target addition T-Apt and poly-A Apt by difference … Read more
