Moving to mercury: The first triboelectric effect-based sensor for the detection of Hg2+ ions by using Au nanoparticles (see picture; red) as electrical performance enhancer and recognition element has been successfully demonstrated. This self-powered and stand-alone triboelectric nanosensor has the advantages of simplicity, low cost, high selectivity, and sensitivity.
