Antimicrobial activity and synergistic antibacterial mechanism of a combination of zinc and rare-earth scandium against Escherichia coli

New antimicrobial materials with cerium ions in the composition of salts, solutions, and composite systems based on Ce3+(NO3)3 × 6H2O

“…It correlates with Ce 3+ ions content on the surface of the sample (XPS spectroscopy, Fig. 3(b)), which decreases in the row Ce-240 -Ce-350 -Ce-420 (similar was mentioned in 30 and in 31 for Sc 3+ ions).…”

Preparation and Properties of (Sc2O3-MgO)/Pcl/Pvp Electrospun Nanofiber Membranes for the Inhibition of Escherichia coli Infections

“…On the other hand, there are many kinds of active sites on the surface of Sc 2 O 3 -MgO, such as lattice limited hydroxyl, free hydroxyl, and ion holes, which can be used as adsorption and surface reaction centers and cause mechanical damage. Scandium (Sc 3+ ) has been shown to have the ability to inhibit the growth of Klebsiella pneumoniae, E. coli, and Pseudomonas aeruginosa [40][41][42]. The purpose of doping Sc 3+ in the nano-MgO lattice is to increase the lattice defects and then increase the ROS content produced during the antibacterial process to enhance the antibacterial property of MgO.…”

Application and mechanisms of metal‐based nanoparticles in the control of bacterial and fungal crop diseases

“…As a consequence, the antibacterial activity of the Zn and silica composites was increased from 65% to 90%. 71…”

“…The addition of the REE Sc increases the specific surface area of the Zn and silica nanocomposites, resulting in increased reactive oxygen species (ROS). As a consequence, the antibacterial activity of the Zn and silica composites was increased from 65% to 90% 71 …”
