A reusable sensing strategy employing magnetic nanoparticles and thymine-containing aptamers was developed to detect Hg2+ in real water samples based on turn-on'' resonance light scattering. The LOD was as low as 500 fM (S/N=3), and the present sensor can be repeatedly used for at least seven cycles.
