Abstract: A microfluidic device is formed from a cover member and a microfluidic precursor that is prepared from a photosensitive element. The photosensitive element is a solid layer of a photopolymerizable composition that includes at least a binder, a monomer, and a photoinitiator. A method for forming the microfluidic device from the photosensitive element includes imagewise exposing the photopolymerizable layer to actinic radiation through a mask and treating to form a relief surface having microstructures or features, such as one or more channels and one or more chambers, that are suitable for use in the microfluidic device. The method provides microstructures that can be formed to have different dimensions that provide particular advantages for a microfluidic device that is operated by degas-driven flow to transport a fluid through the microstructures.

Abstract: Disclosed herein are compositions and methods to treat skin with a peracid-based benefit agent. The peracid benefit agent can be used for a benefit such as the prevention or treatment of acne, skin whitening, skin bleaching, skin conditioning, reducing the appearance of skin wrinkles, skin rejuvenation, reducing dermal adhesions, and preventing, reducing or eliminating body odors or any combination thereof. The peracid may be enzymatically generated from a carboxylic acid ester substrate using an enzyme having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a skin-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the skin surface.

Abstract: Disclosed herein are compositions and methods to treat hair with a peracid-based benefit agent. The peracid benefit agent can be used for hair bleaching, hair weakening, hair removal, hair waiving, hair straightening or any combination thereof. The peracid may be enzymatically generated from a carboxylic acid ester substrate using an enzyme having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a hair-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the hair surface.

Abstract: A coating composition having an multicopper oxidase enzyme and an oxidizable substrate in combination with an organic binder polymer which may be dispersed or dissolved in a non-aqueous liquid vehicle.

Abstract: The invention is directed to a method for preparing an oxygen scavenging film and package by inclusion of an oxygen scavenging coating that is activable upon exposure to water vapor during final package assembly. The film includes a composition having a non-aqueous liquid vehicle, a multicopper oxidase enzyme, an oxidizable substrate and an organic binder polymer, wherein the polymer is dissolved or dispersed in the liquid vehicle, wherein the enzyme and the substrate are in particulate form and dispersed in the liquid vehicle; and wherein the liquid vehicle is evaporated.

Abstract: The composition of the present invention, combining multicopper oxidase enzyme, oxidizable substrate, and iron, exhibits a rate of oxygen scavenging that is in excess of that predicted from the rule of mixtures applied to the combination of enzyme/substrate and iron/substrate compositions that are known in the art.

Abstract: A coating composition having a multicopper oxidase enzyme and an oxidizable substrate in combination with a organic binder polymer which may be dispersed or dissolved in a non-aqueous liquid vehicle.

Abstract: The invention is directed to a method for preparing an oxygen reduced film and package by inclusion of an oxygen scavenger coating that is activable upon exposure to water vapor during final package assembly. The film includes a composition having a non-aqueous liquid vehicle, a multicopper oxidase enzyme, an oxidizable substrate and an organic binder polymer, wherein the polymer is dissolved or dispersed in the liquid vehicle, wherein the enzyme and the substrate are in particulate form and dispersed in the liquid vehicle; and wherein the liquid vehicle is evaporated.

Abstract: Oxygen is removed or maintained in a sealed container by electrochemically reducing the oxygen to water using an enzymatic O2 scavenging system based on a laccase enzyme. Activation of the O2 scavenging system typically occurs by water (liquid or vapor) adsorption; in preferred embodiments, ascorbate and isoascorbate (and their corresponding acids) are especially advantageous for their dual role as reductant and hygroscopic agent. The capacity of the O2 scavenging system can be manipulated by altering the concentration of reductant that is included in the O2 scavenging composition. The O2 scavenging system can be prepared in a variety of formats (e.g., inks, labels, packets, liners, patches, caps, within the packaging material itself) and is readily produced by apparatuses conventionally used in the industry on a high speed continuous basis.
