A mercury(ii) ion sensor device based on an organic field effect transistor with an extended-gate modified by dipicolylamine†
Abstract
Herein, we report an organic field effect transistor (OFET) with an extended-gate modified by an artificial receptor for the detection of mercury(II) ions (Hg2+) in water. The sensor device is easy to fabricate, reusable, disposable, and portable. Thus OFET sensors could be applied for low-cost on-site detection of Hg2+.
