METHOD OF OBTAINING SURGICAL SUTURE MATERIALS WITH ANTIBACTERIAL PROPERTIES BY ATOMIC LAYER DEPOSITION Russian patent published in 2023 - IPC A61L17/04 A61L17/14 

FIELD: application of atomic layer deposition (ALD) nanotechnology in medicine and veterinary medicine.

SUBSTANCE: invention relates to the development of a method for producing surgical sutures with an antibacterial nanocoating. A method of producing surgical suture materials with antibacterial properties is proposed, the said method includes applying an antibacterial functional nanomaterial, a titanium-vanadium oxide nanofilm (TiVO_x), 12 nm thick, to the surface of a polypropylene surgical suture by atomic layer deposition (ALD). Titanium tetrachloride (TiCl₄), vanadium oxytrichloride (VOCl₃) and water (H₂O) are used as precursors for ACO TiVO_x. The temperature at which ASO is carried out is 80°C.

EFFECT: developed method makes it possible to obtain an antibacterial coating on the surface of surgical suture materials with good adhesion.
