Attached file provides supplementary data for linked article. The rapid emergence of antibiotic-resistant bacterial strains warrants new strategies for infection control. NanoZymes are emerging as a new class of catalytic nanomaterials that mimic the biological action of natural enzymes. The development of photoactive NanoZymes offers a promising avenue to use light as a “trigger” to modulate the bacterial activity. Visible light activity is particularly desirable because it contributes to 44% of the total solar energy. Here we show that the favorable band structure of a CuO-nanorod-based NanoZyme catalyst (band gap of 1.44 eV) allows visible light to control the antibacterial activity. Photomodulation of the peroxidase-mimic activity of CuO nanorods enhances its affinity to H2O2, thereby remarkably accelerating the production of reactive oxygen species (ROS) by 20 times. This photoinduced NanoZyme-mediated ROS production catalyzes physical damage to the bacterial cells, thereby enhancing the antibacterial performance against Gram-negative-indicator bacteria Escherichia coli.
