Field: Micro-structural and nano-technology (Chemistry)
Classification: CPC C  A  H  B | IPC A  B  C

Claim 0:
1. A method for preventing or reducing growth of a microorganism on a surface, the method comprising:
applying spinel ferrite nanoparticles onto the surface;
wherein the spinet ferrite nanoparticles comprise a chromium-substituted copper ferrite of formula (I)

CuCrxFe2-xO4  (I),, X being in a range of from 0.4 to 1,
wherein the spinel ferrite nanoparticles are in contact with the surface for a time in a range of from 0.1 to 24 hours, and
wherein a count of the microorganism on the surface is reduced more by the chromium-substituted copper ferrite than a copper ferrite without chromium substitution.
