Abstract
A method of manufacturing a flexible intrinsically antimicrobial absorbent porosic composite controlling for an effective pore size using removable pore-forming substances and physically incorporated, non-leaching antimicrobials. A flexible intrinsically antimicrobial absorbent porosic composite controlled for an effective pore size composited physically incorporated, high-surface area, non-leaching antimicrobials, optionally in which the physically incorporated non-leaching antimicrobial exposes nanopillars on its surface to enhance antimicrobial activity. A kit that enhances the effectiveness of the intrinsically antimicrobial absorbent porosic composite by storing the composite within an antimicrobial container.
Claims17
An absorbent non-leaching antimicrobial porous structure composite, comprising:
- a non-leachable antimicrobial physically incorporated upon an antimicrobial sponge by physical anchoring or physical chemical covalent attachment;
- pores within the absorbent non-leaching antimicrobial porous structure composite, wherein the pores retain the non-leachable antimicrobial within the pores, and wherein the non-leachable antimicrobial is exposed to the interior of the pores, wherein the non-leachable antimicrobial is selected from the group consisting of one or more of copper, bismuth, gold, aluminum, boron, selenium, gallium, sulfur, germanium, barium, manganese, vanadium, lead, beryllium, cadmium, chromium, arsenic, tellurium, mercury, thallium, uranium, tin, antimony, indium, iron, cobalt or nickel, strontium, scandium, titanium, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, lanthanum, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, actinium, rutherfordium, dubnium, seaborgium, bohrium, hassium, meitnerium, darmstadtium, roentgenium, copernicium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, thorium, protactinium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, and lawrencium.
A method of manufacturing an absorbent non-leaching antimicrobial porous matrix composite, comprising:
- making or obtaining a flexible porous solid matrix substrate that forms a pore-containing solid matrix;
- physically incorporating a non-leachable antimicrobial within or upon a pore-containing solid matrix, wherein the pore-containing matrix comprises a plurality of matrix pores, wherein each matrix pore comprises an interior, and wherein the non-leachable antimicrobial has exposure to the interior of the matrix pores;
- wherein the non-leachable antimicrobial is physically incorporated within the pore-containing solid matrix by the step comprising:
- mixing the non-leachable antimicrobial with a solidifiable matrix in flowable form with a removable pore-forming substance, and wherein the non-leachable antimicrobial is distributed and physically enveloped within the solidifiable matrix, and wherein the solidifiable
- matrix is solidified while physically enveloping the pore-forming substance and the non-leachable antimicrobial to form the pore-containing solid matrix, and
- wherein the non-leachable antimicrobial is selected from the group consisting of one or more of copper, bismuth, and sulfur.
A method of manufacturing an absorbent non-leaching antimicrobial porous matrix composite, comprising:
- making or obtaining a flexible porous solid matrix substrate that forms a pore-containing solid matrix;
- physically incorporating a non-leachable antimicrobial within or upon a pore-containing solid matrix, wherein the pore-containing matrix comprises a plurality of matrix pores, wherein each matrix pore comprises an interior, and wherein the non-leachable antimicrobial has exposure to the interior of the matrix pores;
- removing any non-physically incorporated non-leachable antimicrobial from the pore-containing solid matrix, wherein the
- non-leachable antimicrobial is physically incorporated within the pore-containing solid matrix by the step comprising:
- mixing the non-leachable antimicrobial with a solidifiable matrix in flowable form with a removable pore-forming substance, and wherein the non-leachable antimicrobial is evenly distributed and physically enveloped within the solidifiable matrix, and wherein the solidifiable matrix is solidified while physically enveloping the pore-forming substance and the non-leachable antimicrobial to form the pore-containing solid matrix, and
- wherein the non-leachable antimicrobial is selected from the group consisting of one or more of copper, bismuth, and sulfur.
