 In this study, researchers developed two new types of nanoparticles, cadmium sulfide, cds, and zinc sulfide, ZNS, which have been shown to be effective at killing oral pathogens. These nanoparticles were formed through a fast, eco-friendly process and their sizes ranged between 10 nanometers and 25 nanometers. Additionally, they had a spherical shape and contained amino acids, which helped them form more easily. The nanoparticles also showed strong antibacterial properties against common oral pathogens, including Streptococcus sp, Staphylococcus sp, Lactobacillus sp, and Candida albicans. This suggests that cds and ZNS nanoparticles could potentially be used as a safe and effective alternative to traditional treatments for oral diseases.
