Abstract

We report a method for determining dopamine in serum <italic>via</italic> colorimetric sensing. This new method adopts bromelain-templated MnO<sub>2</sub> nanosheets that possess high oxidase activity. 3,3′,5,5′-Tetramethylbenzidine (TMB) can be directly oxidized by bromelain-MnO<sub>2</sub> nanosheets to oxTMB products.
