AB  - 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), 3,4-methylenedioxymetamphetamine (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(-1)) and 
      relative standard deviations (<10%) have been achieved. The proposed kit has been 
      successfully validated and applied to the analysis of amphetamine-like drugs 
      street samples. The kit allows the in-situ screening of the mentioned illicit 
      drugs owing to its simplicity, rapidity and portability, with excellent sensor 
      stability and at a very low-cost.
