Abstract Copper-based nanozyme has shown the superior in oxidase-like activities due to its electron transfer ability between Cu (I) and (II) sites during catalytic reactions. Herein, a Cu(I)-MOF (Cu-Mel) was readily synthesized by traditional hydrothermal process using precursors of Cu+ melamine, which then used laccase-like reactions for first time. Some means, such as X-ray diffraction (XRD), scanning microscope (SEM), Fourier transform infrared spectroscopy (FTIR) photoelectron (XPS) were employed character microstructure Cu-Mel. The oxidation 4-aminoantipyrine (4-AP) 2,4-dichlorophenol (2,4-DP) adopted evaluate resulting conditions including temperatures, presence alcohols ionic concentrations, varied optimize activities, based on that, highest activity is presented with higher maximum reaction rate (Vmax). good storage stability also Cu-Mel utilized degradation Congo red, showing efficiency. These findings facilitate development laccase mimics serve foundation design applications Cu-MOFs realm.

A copper-based nanoenzyme (Cu-BL) co-modified by L-L-lysine and 2-2-amino terephthalic acid has laccase-like activity fluorescence characteristics. Based on this, a colorimetric fluorescent dual-mode sensor was developed to visually quantitatively detect tetracycline antibiotics (TCs), including (TC), chlortetracycline (CTC), oxytetracycline (OTC). In the detection system, TCs can inhibit generation of singlet oxygen (1O2) weaken ability 2,4-dichlorophenol (2,4-DP) be oxidized into pink-colored quinone substances. The linear ranges are 0.5–80 μM, 1–80 0.25–80 limits 0.27 0.22 0.26μM, respectively. addition, due inner filter effect, interact with Cu-BL, increase in antibiotic concentration, intensity will decrease. smartphone sensing platform is combined signal for rapid visual quantitative antibiotics. Generally speaking, colorimetric/fluorescence demonstrates good stability, high specificity, strong anti-interference capabilities, highlighting its practical application potential. This work expected offer novel insights development multifunctional nanoenzymes integration multi-mode platform.
