Implementation of a new integrated d-lactic acid biosensor in a semiautomatic FIA system for the simultaneous determination of lactic acid enantiomers. Application to the analysis of beer samples.
本文报道了一种用于D-乳酸测定的集成安培生物传感器。该传感器以溅射金膜修饰的不锈钢盘电极为基底,将D-乳酸脱氢酶(DLDH)、脱氢酶(DP)和氧化还原介质四硫富瓦烯(TTF)通过透析膜共固定。在搅拌溶液中,于+0.15 V(vs Ag/AgCl)进行安培检测,D-乳酸在1.0×10^-4至3.8×10^-3 g L^-1范围内呈线性...
