“…This may be due to the release of copper ions as a result of microwave heat. As the radius of copper ions (Cu 2+ : 0.073 nm, Cu + : 0.077 nm) is smaller than that of cerium ions (0.097 nm), [ 53 ] some of the copper ions enter the CeO 2 surface or subsurface, which is beneficial to enhance the synergistic effect of copper and cerium and improve the antibacterial effect.…”

Osteomyelitis caused by bacteria is a deep-seated lesion and is often treated clinically with antibiotics. Long-term use of antibiotics may predispose bacteria to develop resistance. Here, CuCeO x material is applied to treat infectious bacterial osteomyelitis using microwave (MW)-assisted bacterial killing. Heat generation occurs as a result of the dielectric properties of the material under MW irradiation, and the material generates reactive oxygen species (ROS) under MW irradiation. Heat and ROS increase the thermal sensitivity and permeability of bacterial cell membranes, and the released copper ions easily penetrate the bacterial membrane and react with H 2 O 2 to produce a toxic hydroxyl group inside the bacteria, leading to the bacteria's eventual death. This is due to the synergistic effect of the MW thermal effect, ROS, and the breaking of the equilibrium within the bacteria. CuCeO x can effectively treat osteomyelitis caused by Staphylococcus aureus using MW irradiation. This study can safely and effectively address the challenge of deep tissue infections by shedding light on non-invasive antimicrobial systems and using MW thermal therapy and MW dynamics to achieve therapeutic results.
