Detection and identification of designer drugs the latest release in the emerging issues in analytical chemistry series presents both an overview and a guide to techniques for anyone studying or engaging in designer drug analysisproliferation of the synthesis and use of designer drugs is a serious public health problem with social economic and legal implications. Download detection and identification of designer drugs emerging issues in analytical chemistry eb. In this study we utilized surface enhanced raman spectroscopy sers to demonstrate that artificial dyes can be directly detected on hair this spectroscopic technique is capable of a confirmatory identification of analytes with single molecule resolution requires minimal sample and has the advantage of fluorescence quenching. A disposable low cost colorimetric sensor array has been created by pin printing onto a hydrophilic membrane 16 chemically responsive nanoporous pigments that are comprised of indicators immobilized in an organically modified silane ormosil the array has been used to detect and identify 14 different natural and artificial sweeteners at millimolar concentrations as well as commonly used
