Summary: This study focuses on improving the separation and dispersibility properties of titanium dioxide (TiO2) in water disinfection by grafting lactose-containing glycopolymers onto magnetic TiO2 nanomaterials. The Fe3O4@TiO2@poly(LacA) showed excellent ability to identify and trap E. coli, exhibiting promising photocatalytic antibacterial activity. The magnetic characteristics of Fe3O4@TiO2/glycopolymers suggest potential for easy recovery using an external magnetic field, making them a candidate for photocatalysis water disinfection.

Summary: In this study, a highly efficient nanoheterojunction material called UCZM was synthesized, which exhibited a remarkable response to the full spectrum of sunlight and showed outstanding performance in degrading dye and inactivating bacteria. The crucial role of NaGdF4:Yb,Er in activating ZIF-8 and MnO2 through Forster resonance energy transfer was revealed, and the formation of a Z-type heterojunction promoted the efficient separation of photogenerated carriers. Furthermore, UCZM demonstrated excellent biosafety properties.

Summary: In this study, Elaeagnus mollis polysaccharide (EMP) was used to modify black phosphorus (BP) and create a new compound EMP-BP with enhanced stability and activity. EMP-BP exhibited significantly increased antibacterial activity compared to EMP and BP, potentially through the generation of reactive oxygen species (ROS) and the action of active polysaccharides on the cell membrane. EMP-BP also demonstrated inhibitory effects on biofilm formation and virulence factor expression of Staphylococcus aureus, with good biocompatibility and no significant development of antibiotic resistance.

Summary: The synthesis of functional antibacterial nanoplatforms that can kill pathogenic bacteria is urgently needed. In this study, a multimodal antibacterial nanoplatform (Van/PCN) was synthesized by combining PCN-224 and vancomycin (Van). Van/PCN utilizes Van and ROS to kill bacteria, achieving a synergistic antibacterial effect. This antibacterial nanoplatform shows great potential in treating bacterial infections caused by Gram-positive pathogens due to the sensitivity of Gram-positive bacteria to Van.

Summary: Photodynamic inactivation (PDI) using sulfonated polystyrene nanoparticles with encapsulated hydrophobic 5,10,15,20-tetraphenylporphyrin (TPP-NP) photosensitizers showed high phototoxicity on both Gram-positive (including multi-resistant) and Gram-negative bacterial strains, with Gram-positive bacteria being more sensitive to TPP-NPs. Atomic force microscopy detected morphological changes in bacteria after PDI treatment.

Summary: In this study, silica-supported Ag NPs (SiO2@Ag) were synthesized as effective antibacterial agents through a wet-impregnation method. The TEM analysis confirmed the formation of SiO2@Ag with excellent antibacterial activity against E. coli bacteria at a concentration up to 1.00 mg/mL, fully inhibiting bacterial growth. The obtained material also showed good adhesion to steel and polyethylene substrates, with high inhibition effect against E. coli bacteria.

Summary: In this study, a polypropylene (PP) based modified-ZIF-8 antibacterial masterbatch was prepared using surface modification and torque blending method to address the issue of poor compatibility between modified-ZIF-8 nanoparticles and mask matrix PP and melt-blown materials. Characterization results confirmed that the antibacterial masterbatch maintained the chemical and crystal structure of modified-ZIF-8 and the thermal stability of PP. The photocatalytic performance showed that the antibacterial masterbatch exhibited narrower band gap and superior photocatalytic activity compared to modified-ZIF-8. The antibacterial properties of the masterbatch against Staphylococcus aureus and Escherichia coli followed a Beta distribution, indicating second-order kinetic behavior, and reached maximum at a modified-ZIF-8 loading of 2% of the total weight. Complete eradication of the bacteria was achieved after 30 minutes of simulated sunlight irradiation. These findings suggest the potential application of PP based modified-ZIF-8 antibacterial masterbatch in photocatalytic antibacterial masks.
