Development of Nanomaterial-Modified Impedimetric Aptasensor-A Single-Step Strategy for 3,4-Methylenedioxymethylamphetamine Detection.
Developing rapid, sensitive detection methods for 3,4-Methylenedioxymethylamphetamine (MDMA) is crucial to reduce its current misuse in the world population. With that aim, we developed an aptamer-modified tin nanoparticle (SnNP)-based nanoarchitecture as an electrochemical sensor in this study. This platform exhibited a high electron transfer rate with enhanced conductivity arising from its large surface area in comparison to the bare electrode. This observation was explained by the 40-fold higher electroactive surface area of SnNPsAu, which provided a large space for 1.0 μM
