Herein we report a simple and cost-effective method for the direct electrochemical detection of redox-active small organic analytes in complex media, such as soil dispersions, human serum and milk, without sample pre-treatment using an indium tin oxide (ITO) electrode modified with permselective membranes consisting of vertically ordered surfactant micelles and silica mesochannels (OSM@SM). The OSM@SM/ITO electrode displayed excellent anti-interference and anti-fouling ability.
