Facile construction of functional nanomaterials with laccase-like activity is important in sustainable chemistry since laccase featured as an efficient and promising catalyst especially for phenolic degradation but still has the challenges high cost, low activity, poor stability unsatisfied recyclability. In this paper, we report a simple method to synthesize nanozymes enhanced by self-assembly copper ions various imidazole derivatives. case 1-methylimidazole ligand, as-synthesized nanozyme (denoted Cu-MIM) highest yield best among prepared. Compared laccase, Km Cu-MIM phenol much lower, vmax 6.8 times higher. addition, maintains excellent variety harsh environments, such pH, temperature, salt concentration, organic solvents long-term storage. Based on nanozyme, established quantitatively detecting concentration through smartphone, which believed have applications environmental protection, pollutant detection other fields.

The development of superior functional enzyme mimics (nanozymes) is essential for practical applications, including point-of-care diagnostics, biotechnological biofuels, and environmental remediation. Nanozymes with the ability to control their catalytic activity in response external fuels offer functionally valuable platforms mimicking nonequilibrium systems nature. Herein, we fabricated a supramolecular coordination bonding-based dynamic vesicle that exhibits multienzymatic activity. nanozyme shows effective laccase-like KM value better than native higher stability harsh conditions. Besides, nanostructure demonstrates an efficient peroxidase-like NADH properties. Generation luminescence from luminol oxidation dopamine are efficiently catalyzed by high sensitivity, which useful detections. Notably, active laccase-mimetic pH variation, has never been explored before. While neutral/high leads self-assembly, low disintegrates assembled nanostructures consequently turns off Altogether, self-assembled Cu2+-based vesicular presents pH-fueled dissipative system demonstrating temporally controlled
