Background And Aim: In dental clinics, disinfecting alginate impression materials is a critical practice to prevent cross-infection. Recently, zinc oxide nanoparticles (ZnO NPs) have been explored for their potential antimicrobial properties, making them promising additives for dental materials. This study investigates the antimicrobial activity of ZnO NPs incorporated into alginate impression materials and assesses the impact on material flow.

Bacterial infections are a major global health challenge, posing severe risks to human well-being. Although numerous strategies have been developed to combat bacterial pathogens, their practical application is often hindered by operational constraints. Photocatalytic materials have emerged as promising candidates for bacterial disinfection and food preservation due to their efficiency and sustainability.

Researching disinfection strategies is pivotal because effectively eliminating bacteria and their byproducts during root canal treatment (RCT) remains a challenge. This study investigated the antimicrobial efficacy of natural antimicrobial compounds, propolis (PRO) and copaiba oil-resin (COR), compared to conventional agents in Endodontics. Antimicrobials were tested against endodontic pathogens via macrodilution with standardized inoculums to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC).

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.

Based on the potential bactericidal properties of borate, we synthesized controlled-release borate (CRB) as a novel biocide to inhibit microbial proliferation in a recirculating cooling water system (RCS). In this study, toxicity experiments of CRB were conducted on the dominant bacteria and algae isolated from an actual RCS. The effects of CRB on biocidal performance and genotoxicity were evaluated in a simulated RCS.
