These nanoparticle templates, produced with a rapid and scalable process, namely laser annealing, were used as a highly sensitive surface sensor to monitor the adsorption of both metallic lead and a lead salt from aqueous solutions, showing a measurable optical response due to a surface abundance of lead as low as 100 ppm from 0.3 ml of Pb2SO4 solutions, with concentrations less than 20 ppm.
