Simple enzyme-free detection of uric acid by an in situ fluorescence and colorimetric method based on Co-PBA with high oxidase activity

Abstract

In this work, we simply and low-cost prepared cobalt-doped Prussia Blue analog (Co-PBA), which can directly oxidize 10-Acetyl-3,7-dihydroxyphenoxazine and 3,3',5,5'-tetramethylbenzidine (TMB), the products were high quantum yields of fluorescent resorufin...
