Research ArticleOpen accessIn the abstractIncreasing the Critical Micellar Concentration (CMC) of Surfactants Enhances the Removal of Pathogenic Bacteria, P. Aeruginosa, and S. Aureus from WastewaterImen Laadouze, Emna Grami et al.Antimicrobial effects of increasing Critical Micellar Concentration (CMCn) (n varying from 1-12) on Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 29213 over time of 5-, 10, and 20-minute exposures were evaluated. Three types of surfactants (Cetyltrime Thylammonium Ammonium Bromide (CTAB), Dodecyl Sulfate (SDS), and TX-100) were evaluated. The results showed that CTAB had the greatest impact on both bacterial … …American Journal of Environmental Sciences, Vol. 22, Issue 1 · 8 May 2026 · 1,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytocompatibility and Antimicrobial Properties of Silver Nanoparticles-Loaded AMPs in the Oral CavityYanli Lv, Weikai ZhangPostoperative infection following oral metal implantation is a key factor that affects the success rate of surgery. This infection is mainly caused by bacterial biofilms. Traditional single antibacterial coatings have limitations, including a narrow antibacterial spectrum and poor cytotoxicity or stability. This study combined silver nanoparticles (AgNPs) and the synthetic antimicrobial peptide GL13K using electrostatic self-assembly technology to create a … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 24 Apr 2026 · 1,685 accessesView PDFCite
