SYNTHESIS OF A COLORIMETRIC SILICA SOL-GEL SENSOR FOR THE DETECTION OF METHAMPHETAMINE**
A silica sol–gel colorimetric sensor was successfully developed for the detection of methamphetamine. Simon’s reagents were entrapped within the polymeric network of the silica sol–gel matrix. The sol–gel colorimetric sensor was synthesized to demonstrate the qualitative analysis of methamphetamine with digital image colorimetry using a Red-Green-Blue (RGB) basic color program. The interaction of the colorimetric Simon’s reagents, the functionality of the reagents, and the structural integrity of the doped silica sol-gel were examined using thermogravimetric analysis, RGB color program, and UV-Vis spectroscopy. These results demonstrate that the sol–gel matrix has the potential to be used as a colorimetric sensor for methamphetamine detection. The experimental methodology and preliminary results of the study will be presented.
