Nerve agents detection using a Cu2+/L-cysteine bilayer-coated microcantilever.
A Cu2+/l-cysteine bilayer-coated microcantilever undergoes bending upon exposure to dimethyl methyl phosphonate at concentration as low as 10-15 M due to the complexation of a phosphonyl group with the Cu2+/l-cysteine bilayer on the microcantilever surface.
