中文摘要	a self-powered electrochemical sensor has been facilely designed for sensitive detection of hg(2+) based on the inhibition of biocatalysis process of enzymatic biofuel cell (bfc) for the first time. the as-prepared one-compartment bfc, which was consisted of alcohol dehydrogenase supported on single-walled carbon nanohorns-based mediator system as the anode and bilirubin oxidase as the cathodic biocatalyst, generated an open circuit potential (v(oc)) of 636 mv and a maximum power density of 137 mu w cm(-2). it was interestingly found that the presence of hg(2+) would affect the performance of the constructed bfc (e.g., v(oc)). taking advantage of the inhibitive effect of hg(2+), a novel self-powered hg(2+) sensor has been developed, which showed a linear range of 1-500 nm (r(2) = 0.999) with a detection limit of 1 nm at room temperature. in addition, this bfc-type sensor exhibited good selectivity for hg(2+) against other common environmental metal ions, and the feasibility of the method for hg(2+) detection in actual water samples (i.e., tap, ground, and lake water) was demonstrated with satisfactory results.
