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.

The insertion of β-amino acids and replacement of the amide bond with a urea bond in antimicrobial peptide sequences are promising approaches to enhance the antibacterial activity and improve proteolytic stability. Herein, we describe the synthesis, characterization, and antibacterial activity of short αβ cationic hybrid peptides LA-Orn-βAcc-PEA, ; LA-Lys-βAcc-PEA, ; and LA-Arg-βAcc-PEA, in which a C12 lipid chain is conjugated at the N terminus of peptide through urea bonds. Further, we evaluated all the peptides against both and methicillin-resistant (MRSA) and their multidrug resistant (MDR) clinical isolates.

Recently, researchers have used silver nanoparticles (AgNPs) coupled with humic acid (HA) as antimicrobial agents. Herein, AgNPs were prepared and coupled with humic acid for their antimicrobial activities. The as-prepared AgNPs coupled with humic acid (HA) were characterized by an atomic force microscope (AFM), X-ray powder diffraction (XRD), zeta potential, zeta sizer, Fourier-transform infrared (FT-IR) spectroscopy, and UV-VIS spectrophotometer.
