摘要： A hydrophilic, pressure-sensitive adhesive composition prepared by irradiating solid poly(N-vinyl lactam) with ionizing radiation to crosslink the poly(N-vinyl lactam) and thereafter mixing the radiation-crosslinked poly(N-vinyl lactam) with essentially unirradiated plasticizer in an amount sufficient to form a cohesive, pressure-sensitive adhesive composition. The composition is useful as a biomedical adhesive for transmitting or receiving electrical signals as a component of a biomedical electrode. The composition is also useful as a drug delivery device to deliver pharmaceuticals or other active ingredients to or through mammalian skin. The composition is also useful as a component in a skin covering for protecting mammalian skin or mammalian skin openings with antimicrobial agents. A method of preparation of the composition is also disclosed.

摘要： A method of treating a patient with a microneedle array having an active agent disposed on at least a portion of one or more of the microneedles, wherein the array with active agent is characterized by a first optical response when probed with a selected incident light spectrum. The array with active agent is applied to a skin surface, optionally allowed to remain on the skin surface for a specified time, and removed. The used array is probed with the selected incident light spectrum, a second optical response is sensed, and the difference between the first optical response and the second optical response is determined and compared to a predetermined threshold value.

摘要： A pressure-sensitive medical sealant composition comprising (a) a crosslinked, swellable polymeric matrix made from an N-vinyl lactam monomer and a multi-ethylenically unsaturated compound, wherein the ethylenic groups are vinyl groups, allyl groups or methallyl groups, which groups are bonded to nitrogen or oxygen atoms; (b) a plasticizer; and (c) an antimicrobial. The medical sealant is highly moisture vapor transmissive and is capable of incorporating large concentrations of iodine. The composition can be used in a variety of medical applications including as a teat plug, a wound or burn dressing, or as a sealant to seal junctions between medical instruments penetrating the skin and the skin. A method of preparing the medical sealant composition in a caulkable form is also disclosed.
