More specifically, fluorescent copper nanoclusters have been obtained during the enzymatic reaction of tyramine oxidase and tyramine in the presence of Cu(II); the fluorescence intensity being proportional to the concentration of tyramine. The nanoclusters obtained show fluorescence at 445 nm by being excited at 320 nm and have been characterized by TEM, EDX, and XPS. The formation mechanism has also been studied, suggesting that under the optimal conditions (0.1 M MES buffer and pH = 6), the formation of the nanoclusters is due to the reducing properties of the product of the enzymatic reaction (p-hydroxybenzaldehyde) in MES buffer. 2023-04-20T01:22:48Z 2023-04-20T01:22:48Z 2023 Book https://link.springer.com/article/10.1007/s00216-023-04571-4 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8105 en application/pdf Springer
