Electrochemical analysis of specific catalase activity during development of Aspergillus flavus and its correlation with aflatoxin B1 production.

黄曲霉毒素B1（AFB1）污染会造成巨大经济损失。为探究黄曲霉（Aspergillus flavus）发育过程中过氧化氢酶（CAT）活性与AFB1产生的相关性，作者构建了一种电化学CAT活性传感器，通过测定CAT酶促降解后剩余的过氧化氢（H2O2）来间接定量CAT活性。该传感器以钯纳米颗粒（PdNPs）/碳化细菌纤维素（CBC）纳米...
