Abstract

Single-layer graphene, decorated with Au nanoparticles, and a specially designed peptide are used for the first time in the detection of decabrominediphenyl ether using impedance spectroscopy. Biosensor calibration is presented, showing a good linear response from 5% to saturated dissolutions (100 ppt). Selectivity towards brominated species is demonstrated by lack of response to molecules with similar structures but without any bromines.
