Abstract
Methods of forming spinel ferrite nanoparticles containing a chromium-substituted copper ferrite as well as properties (e.g. particle size, crystallite size, pore size, surface area) of these spinel ferrite nanoparticles are described. Methods of preventing or reducing microbe growth on a surface by applying these spinel ferrite nanoparticles onto the surface in the form of a suspension or an antimicrobial product are also described.

1-19. (canceled)
A trimetal oxide antimicrobial treatment composition for multi-drug resistant bacteria, comprising:
- spinel ferrite nanoparticles, and
- a liquid medium;
- wherein the spinel ferrite nanoparticles comprise at least one chromium-substituted copper ferrite selected from the group consisting of CuCr0.4Fe1.6O4, CuCr0.6Fe1.4O4, and CuCr0.8Fe1.2O4, and have an average particle size of from 47.6 nm to 69.9 nm;
- and
- wherein the spinel ferrite nanoparticles have an angular, spinel, or irregular form, and are suspended in the liquid medium.
