NADP-dependent oxidoreductase compositions, and electrodes, sensors and systems that include the same. Analyte sensors include an electrode having a sensing layer disposed thereon, the sensing layer comprising a polymer and an enzyme composition distributed therein. The enzyme composition includes nicotinamide adenine dinucleotide phosphate (NAD(P).sup.+) or derivative thereof; an NAD(P).sup.+-dependent dehydrogenase; an NAD(P)H oxidoreductase; and an electron transfer agent comprising a transition metal complex.

An anaerobic biodegradation accelerator (ABA) for a host polymeric material, an ABA-incorporated polymeric material, and methods for production and application thereof are provided. The ABA includes a carrier matrix, at least one biotic component, a protective layer, a biodiversity promotor, a surfactant, a compatibilizer, an antioxidant, a plasticizer and a properties modifier. The ABA significantly enhances biodegradation rate of polymeric materials in anaerobic environments, and does not impact significantly on mechanical properties and other properties of the original polymeric material including food contact safety when they are used in food contact safe products such as cutleries, lunch boxes, cups and cup lids.

In one aspects of the invention, a microcapsule includes a film encapsulating a material. The film is formed by complexation of at least two mutually attractive components initially present in an aqueous dispersion comprising a continuous phase and a dispersed phase. The at least one first component is initially present in the continuous phase and the at least one second component is initially present in the dispersed phase. According to another aspect of the invention, provided is a process for forming microcapsules including the step of injecting a dispersed phase having at least a first component into a continuous phase having at least a second component, where the first component and the second component are mutually attractive, such that a film is formed by complexation of the first charged component and the second charged component.
