Application of Carbon-based Nano Adsorbents in the Extraction of Amphetamines from Urine Samples

Amphetamines, as psychoactive drugs, are extensively abused in society and cause serious mental and physical disorders among young people. Furthermore, the extremely euphoric and excited sense of stimulant consumption leads to dramatic social problems. Determination of various analytes and related metabolites in the complex biological matrices at trace levels has made sample preparation an indispensable part of forensic sciences. According to the problems above, providing high sensitivity, solving some analytical problems like matrix effects in LC-MS-MS, and needing a cleaner extract are remarkable aspects of novel sample preparation methods in drug analysis. Application of nanotechnology and carbon-based nanocomposites seems to bring the above properties in developed and novel sample preparation methods. This review will try to provide an overview of different carbonic nano adsorbents used in sample preparation methods of amphetamines and discuss their superiority over the other nanomaterials.
