The present disclosure relates generally to materials and medical devices impregnated with antimicrobial compounds. More specifically, the materials are medical matrix materials comprising nanopores or nanochannels in which the antimicrobial compounds are disposed. In other embodiments, medical matrix materials comprises nanomaterials and antimicrobials distributed throughout the material. The materials described herein are useful for a broad spectrum of medical devices and consumer products. The present disclosure further provides methods of making the antimicrobial materials and medical devices disclosed herein.
An antimicrobial medical device comprising a medical matrix material having nanopores or nanochannels and an antimicrobial agent incorporated therein.
The antimicrobial medical device of any one of claims 1 to 10, wherein the nanopores or nanochannels comprise about 0.1% to about 10% of the volume of the medical matrix.
The antimicrobial medical device of claim 12, wherein the silver compound is selected from the group consisting of silver chloride, silver sulfadiazine, silver nitrate and combinations thereof.
The antimicrobial medical device of claim 12, where the quaternary ammonium compound is poly(diallyldimethylammonium chloride) (polyDADMAC).
The antimicrobial medical device of claim 12, wherein the antimicrobial agent comprises a silver compound and a chlorhexidine.
The antimicrobial medical device of claim 12, wherein the antimicrobial agent comprises a silver compound and polyDADMAC.
The antimicrobial medical device of claim 12, wherein the antimicrobial agent comprises chlorhexidine and polyDADMAC.
An antimicrobial medical material comprising a medical matrix material having nanopores or nanochannels and an antimicrobial agent incorporated therein.
An antimicrobial medical material comprising a medical matrix, an antimicrobial agent and a nanomaterial.
A method of preparing an antimicrobial medical material having nanopores or nanochannels and an antimicrobial agent disposed therein comprising:
The method of any one of claims 36 to 40, wherein the medical matrix having the nanomaterial disposed therein comprises about 0.5% to about 20% by weight of the nanomaterial. The method of any one of claims 36 to 42, wherein the antimicrobial agent is loaded into the medical matrix by contacting the medical matrix with a solution of the antimicrobial agent.
