Article Snippet: A solid sensor obtained by embedding 1,2-naphthoquinone-4-sulfonate (NQS) into polydimethylsiloxane/tetraethylortosilicate/silicon dioxide nanoparticles composite has been developed to identify and determine amphetamine (AMP), methamphetamine (MAMP), 3,4methylenedioxymetamphetamine (MDMA) and 3,4-methylenedioxyamphetamine (MDA).. The analytes are derivatized inside the composite for 10 min to create a colored product which can be then quantified by measuring the diffuse reflectance or the color intensity after processing the digitalized image.. Satisfactory limits of detection (0.002-0.005 g mL) and relative standard deviations (˂ 10 %) have been achieved.

The sensor has been prepared by immobilized the reagent Co(SCN)2 into polydimethylsiloxane (PDMS).. When exposed to solutions of ketamine at a basic pH, the sensor color changes from brown to blue-purple due to the diffusion of the analyte molecules to the polymeric matrix and subsequent interaction with the reagent particles. |
