摘要：
The proposed procedure for recycling the sensor surface consists of (1) the self-assembly of 2-aminoethanethiol hydrochloride (AET) on the Au substrate, (2) the neutralization of zwitterion-like species, -NH3+Cl- to -NH2 by treatment with a NaOH solution (pH 11), (3) the detection of Cu2+ on the NaOH-treated AET-Au substrate, and finally (4) regeneration of the sensor surface from [-NH2 -> Cu2+] to [-NH3+Cl-] by treatment with 1 M HCl.
