Formulation of magnetic nanoparticles for UV protection of bacteriophages

Abstract

The present invention aims to provide a formulation with magnetic nanoparticles of zinc ferrites (ZnFe2O4) proper as a UV protector for maintaining the lytic activity of bacteriophages in vitro and its subsequent application in controlling bacterial diseases. Herein, the magnetic ferrite nanoparticles Zinc (ZnFe2O4) act as attractants for phytopathogenic bacteria, which increases their biological effectiveness. The formulation comprises magnetic nanoparticles of zinc ferrites (ZnFe2O4) attached to bacteriophages and a method for adhering magnetic nanoparticles of zinc ferrites (ZnFe2O4) to bacterial viruses. Also, it consists of i) placing the bacterial viruses in a culture medium with its host bacteria and subsequently purifying them, ii) adding magnetic zinc ferrite nanoparticles (ZnFe2O4) to the culture medium, and iii) mixing.
