The disinfection services experience acute demand for atomizers. In view of the fact that operation of all atomizing units is based on the same physical principles and that their use is associated with the solution of the same physical problems, for disinfection needs, use can be made of the equipment manufactured by medical industry as well as of the analogous units applied in related spheres: in veterinary, field-crop cultivation, forestry, horticulture, in carrying out finishing works during construction, and in homes. Atomizers manufactured by different bodies are reviewed. The main characteristics of the units are provided.

Photothermal disinfection (PTD) offers promising potential for water purification due to its sustainable and broad-spectrum bactericidal properties, although it is hindered by slow charge separation in photosensitizers. Herein, we present a plasma-mediated PTD technique utilizing an efficient localized heating effect induced by incident light at specific wavelengths for rapid bacterial inactivation. A metallic CuS photosensitizer, derived from electronic waste through a biomimetic transmembrane confined-assembled strategy, facilitates collective and coherent oscillation of free electrons around Cu atoms in the near-infrared range.

Background: Endodontic treatment aims in the preservation of extremely carious primary teeth. For root canal therapy to be successful, root canals must be properly prepared and effectively irrigated .Therefore, it is necessary to select the proper root canal disinfection method to preserve the primary tooth.

Aims: This study aimed to assess the effectiveness of a novel antimicrobial gel, containing copper and silver nanoparticles, for use in root canal disinfection.
Methods: Copper and silver-based gels were created in-house, using a support network of biocompatible polymers, including polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), and polyethylene glycol (PEG). Six experimental groups were created, three containing silver ions and three copper ions, where the PVA, PVP and PEG ratios were also adjusted in each group to test the gel's physical state.

Superbugs in groundwater are posing severe health risks through waterborne pathways. An emerging approach for green disinfection lies at photocatalysis, which levers the locally generated superoxide radical (·O) for neutralization. However, the spin-forbidden feature of O hinders the photocatalytic generation of active ·O, and thus greatly limited the disinfection efficiency, especially for real groundwater with a low dissolved oxygen (DO) concentration.
