Development of a Uricase-Free Colorimetric Biosensor for Uric Acid Based on PPy-Coated Polyoxometalate-Encapsulated Fourfold Helical Metal-Organic Frameworks.

开发一种无尿酸酶、低成本且可靠的尿酸(UA)检测方法仍具挑战性。本文报道了一种简便、低成本且无尿酸酶的 UA 选择性比色传感策略，利用聚吡咯(PPy)包覆的多金属氧酸盐封装四重螺旋金属有机框架 Ag5[bimt]2[PMo12O40]·2H2O (Ag5PMo12) 作为整体过氧化物酶模拟物。结果表明，所得 Ag5PMo12@PPy...
