Abstract

An ultralow concentration of Pb ions is detected by a sensor integrating a peptide nanotube detection platform with a smart peptide function that specifically metalizes the target ion. As the PbII-binding peptide on the nanotube, which bridges two electrodes, templates Pb nanowires, a resistor appears in the circuit, and conductance is detected as the signal for PbII.
