METHOD OF PATHOGENIC BACTERIA INACTIVATION (OPTIONS) Russian patent published in 2023 - IPC C12N13/00 A61L2/08 

FIELD: biotechnology.

SUBSTANCE: following is proposed: a method of non-contact inactivation of pathogenic bacteria by irradiating the surface on which pathogenic bacteria in planktonic form are present with femtosecond laser infrared radiation with a wavelength of 3 μm, with a pulse repetition rate of 10 kHz at a power density of 1.2⋅10⁸W/cm² for 5 min or at a wavelength of 6 µm with a pulse repetition rate of 10 kHz at a power density of 8⋅10⁶ W/cm² for 3–5 min (options).

EFFECT: reduction of colony-forming units of pathogenic bacteria in planktonic form on irradiated surfaces without the use of chemical reagents.
