682 | Biomineralization-inspired copper-cystine nanoleaves capable of laccase-like catalysis for the colorimetric detection of epinephrine | https://doi.org/10.1007/s11705-020-1940-y | Composite | Inspired by the pathological biomineralization behaviour of L-cystine, in this study, we constructed a laccase-like catalyst through the co-assembly of L-cystine with Cu ions. Structural analysis revealed that the formed catalytic Cu-cystine nanoleaves (Cu-Cys NLs) possess a Cu(I)-Cu(II) electron transfer system similar to that in natural laccase. Reaction kinetic studies demonstrated that the catalyst follows the typical Michaelis-Menten model. |
