Abstract
A simple and accessible express method was developed for the detection of morphine in aqueous samples using competitive immunochromatography. A complex of colloidal gold with monoclonal antibodies to morphine was used as the detection agent. The detection limit for morphine in aqueous samples was 10 ng/ml, and the analysis time was 5 min.
