AI Article Synopsis
- This research focuses on improving nano-MgO's antibacterial properties through ion doping (specifically with Sc) and creating specific textures on its surface.
- When 10% Sc is added to the nano-MgO, it results in a uniform, nano-textured surface that enhances its antibacterial effectiveness against bacterial strains E. coli and S. aureus.
- The 10% Sc-doped nano-MgO (SM-10) shows a minimum bactericidal concentration (MBC) of 0.03 mg/mL, significantly better than the non-doped and commercial versions of nano-MgO, indicating strong potential for antibacterial applications.
Article Abstract
In order to obtain the inorganic efficient antibacterial agents, the means of ion doping and morphology construction in this research are used to enhance the antibacterial property of nano-MgO, which is according to the "oxidative damage mechanism" and "contact mechanism". In this work, the nano-textured ScO-MgO are synthesized by doping Sc in nano-MgO lattice through calcining at 600 °C. When the Sc content reaches 10%, the nanotextures on the powders surface are pretty clearly visible and uniform, and the specific surface area and the oxygen vacancy are ideal, so that the 10% Sc-doped powders (SM-10) has the excellent antibacterial property against E. coli and S. aureus (MBC = 0.03 mg/mL). The efficient antibacterial agents in this research have a better antibacterial effect than the 0% Sc-doped powders (SM-0, MBC = 0.20 mg/mL) and the commercial nano-MgO (CM, MBC = 0.40 mg/mL), which have application prospects in the field of antibacterial.
