In Nature, certain organisms can perform microbial corrosion on base metals by oxidation of neutral metallic atoms (H. L. Ehrlich, Appl. Microbiol. Biotechnol., 1997). Herein we describe the first discovery of biological nucleic acids able to catalyze and mediate gold oxidation from neutral Au(0) to trivalent Au(III) under certain oxidative environments provided by mild oxidizing reagent N-bromosuccinimide or amino acids. A new biolithography technique for gold patterning is further developed.
在自然界中，某些生物体可以通过中性金属原子的氧化作用对基本金属进行微生物腐蚀（H. L. Ehrlich，Appl. Microbiol. Biotechnol.，1997）。在此，我们首次发现生物核酸能够在温和氧化剂 N-溴代丁二酰亚胺或氨基酸提供的一定氧化环境下，催化和介导金从中性 Au(0)到三价 Au(III)的氧化。进一步开发了一种新的金图案生物光刻技术。
