Biomineralization-inspired copper-cystine nanoleaves capable of laccase-like catalysis for the colorimetric

Miao Guan, Mengfan Wang, Wei Qi, Rongxin Su, Zhimin He

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2, Pages 310-318 doi: 10.1007/s11705-020-1940-y

Abstract: Inspired by the pathological biomineralization behaviour of L-cystine, in this study, we constructeda 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

Cystine-assisted accumulation of gold nanoparticles on ZnO to construct a sensitive surface-enhanced

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 1, Pages 15-23 doi: 10.1007/s11705-022-2177-8

Abstract: In this study, cystine was introduced to increase the accumulation of gold nanoparticles on zinc oxide, owing to the biomineralization property of cystine.Morphological analysis revealed that the obtained ZnO/Au/cystine composite not only had a higher metalCompared with ZnO/Au, the ZnO/Au/cystine substrate displayed a 40-fold enhancement in the Raman signalFinally, ZnO/Au/cystine displayed excellent performance toward crystal violet and methylene blue in a
