Below:  Schematic illustration of the selective polymeric coating for the detection of explosive chemicals.  A DNT binding peptide as well as a TNT binding peptide were identified through the evolutionary screening process of phage display.  These highly selective receptors were conjugated with hygroscopic poly (ethylene glycol) linkers to provide attachment to chemical sensor surfaces to enhance the sensors selectivity.  Using such selective coatings, sensors may overcome there current limitations of non-specific binding thereby reducing the incidence of false alarms.
