Pb2+ ion sensing using WO3 nanoparticles coated microsized EGaIn liquid metal marbles. A) SEM images for the WO3 nanoparticles coated mLMMs obtained when WO3 suspension with a concentration of 10 mg mL−1 is used. B) DPVs recorded using mLMMs produced with different WO3 nanoparticle suspension concentrations. C) DPVs for increasing concentrations of Pb2+ recorded with mLMMs obtained using WO3 suspension with a concentration of 10 mg mL−1. D) Pb2+ concentration vs amplitude of the oxidation current peak plot.
