摘要：Gold nanotubule membranes were prepared by using electroless deposition of gold within the pores and surfaces of polycarbonate track-etched membranes. And the gold nanotubule membrane was used as an electrode for determination of uric acid in urine samples for the first time. In Britton-Robinson buffer of pH 4.56, uric acid exhibited well-defined differential pulse voltammograms. And the interference between coexistent ascorbic acid and uric acid was overcome owing to the attractive ability of the gold nanotubule electrode to yield a large anodic peak difference ca. 0.404 V (vs. SCE). The proposed method was then applied to the determination of uric acid in urine without any pretreatment. (c) 2007 Ping Hu. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
