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.
Claims18
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 size of the pores is under 3 mm in width at their narrowest dimension,
- and 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,
- and further wherein the surface area to volume ratio of the non-leachable antimicrobial is greater than 6000:1,
- wherein the non-leachable antimicrobial is selected from the group consisting of one or more of copper, silver, zinc, 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, cerium, 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.
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 size of the pores is under 3 mm in width at their narrowest dimension,
- and 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,
- and further wherein the surface area to volume ratio of the non-leachable antimicrobial is in the range of 50,000-1,000,000:1 m−1,
- wherein the non-leachable antimicrobial is selected from the group consisting of one or more of copper, zinc, bismuth, and sulfur;
- and
- wherein the non-leachable antimicrobial represents <5% wt/wt of the composite;
- and further
- wherein the surface of the absorbent non-leaching antimicrobial porous structure composite presents an array of nanopillars, wherein the nanopillars are arranged in an array of blunted spikes.
