Bioinspired Coassembly of Copper Ions and Nicotinamide Adenine Dinucleotides for Single-Site Nanozyme with Dual Catalytic Functions

Analytical Chemistry, Journal Year: 2023, Volume and Issue: 95(5), P. 2865 - 2873

Nanozymes can imitate the catalytic properties of natural enzymes while overcoming limitations such as high cost, poor robustness, and difficulty in recycling. However, rational design facile preparation nanozymes are still demand. Inspired by chemical structure laccase, we report an amorphous metal-organic coordination nanocomposite named CuNAD, which is composed copper ions nicotinamide adenine dinucleotide (NAD+) via a simple coordinating coassembly process. As single-site nanozyme, CuNAD exhibits excellent robustness under extreme conditions, significantly stronger activity for phenolic compounds, 4.02-fold higher sensitivity epinephrine detection than laccase. Furthermore, breaking through functional constraints also able to activate H2O2 at neutral pH, benefiting one-step chromogenic platform cholesterol. This approach demonstrates potential develop biomimicking may boost more insights into structure-function relationship nanozymes.

This study examined the use of modified multiwall carbon nanotubes (M-MWCNTs) with immobilized laccase (L@M-MWCNTs) for removing ciprofloxacin (Cip), carbamazepine (Cbz), diclofenac (Dcf), benzo[a]pyrene (Bap), and anthracene (Ant) from different water samples. The synthesized materials were characterized using an array advanced analytical techniques. physical immobilization onto M-MWCNTs was confirmed through Scanning electron microscope (SEM)-dispersive X-ray spectroscopy (EDS) analysis Brunner-Emmet-Teller (BET) surface area measurements. specific decreased by 65% upon immobilization. There also increase in nitrogen content seen EDS asserting successful results Boehm titration Fourier transform infrared (FTIR) exhibited acidic functional groups after L@M-MWCNTs storage two months maintained 77.8%, 61.6%, 57.6% its initial activity 4 °C, 25 35 respectively. In contrast, free 55.3%, 37.5%, 23.5% at MWCNTs improved storability widened working temperature range laccase. optimum removal conditions studied pollutants pH 5, 1.6 g/L M-MWCNTs. These parameters led to >90% targeted four treatment cycles both synthetic spiked lake water. demonstrated consistent up five even wastewater. adsorption endothermic followed Langmuir isotherm. Oxidation, dehydrogenation, hydroxylation, ring cleavage seem be dominant degradation mechanisms.
