a Absorption spectra of ACh hydrolysis reaction catalyzed by AChE, MOFs in the presence of ChOx and HRP. b The kinetic curve of both MOFs toward ACh. Error bars mean ± s.d. calculated from three independent measurements. c Absorption spectra of DENP hydrolyzed by three catalysts, including AChE, MOF-808, MOF-808-Al. d The kinetic curve of both MOFs toward DENP. Error bars mean ± s.d. calculated from three independent measurements. e Absorbance values (at 652 nm) of ACh hydrolysis reaction catalyzed by AChE and MOFs before and after treatment with DENP. Error bars mean ± s.d. calculated from three independent measurements. f Relative activity of ACh and DENP hydrolysis reaction catalyzed by MOF-808-Al after cycle several times. Error bars mean ± s.d. calculated from three independent measurements. The gray indicates OPH-like activity (bottom), pick indicates AChE-like activity (top).
