    摘要: The present invention provides methods and composition related to lipid layers with increased stability to oxidative degradation. In one embodiment, the invention provides lipid layers comprising antioxidant inclusion molecules that permit biosensors with increased performance and functional lifetime due to increased oxidative protection. In addition to these lipid-layer compositions, the present invention provides methods for further protection of lipid layers from oxidation. These methods include application of solutions and coatings comprising barrier compounds (e.g., trehalose), storage under anaerobic conditions (e.g., with inert gases), storage with oxidant scavengers (e.g., dessicants and catalysts), and packaging with barrier materials (e.g., mylar, polyethylene) that prevent oxidant exposure.

    摘要: This invention relates to a method of immobilizing biocatalysts including protein and cells by co-precipitation with silicate or organosilicate matrices through the action of an organic template molecule. The organic template molecule is in general a polyamine such as polyethylenimine (PEI), or polypeptide compound bearing at least two or three basic residues selected from the group consisting of lysine, arginine, histidine, proline, hydroxyproline, N-methylhistidine, ornithine, taurine, δ-hydroxylysine, and δ-hydroxy-ω-N,N,N trimethyllysine. The invention is also directed to a silica biocomposite comprising co-precipitates of active biocatalysts, silica or organosilicates, and an N-containing organic template molecule. Such silica biocomposites are useful in biocatalysis, and other applications requiring an immobilized biocatalyst. Preferred biocatalysts for this invention are enzymes and whole cells.
