A silicone-based controlled-release device for accelerated proteolytic debridement of wounds.

A new device for rapid enzymatic debridement of cutaneous wounds has been developed using a controlled-release, silicone-based, dried emulsion. A dehydrated serine protease of the subtilisin family, previously untested for wound debridement, was incorporated into the emulsion. This device exhibited excellent storage stability.

"Sweet silicones": biocatalytic reactions to form organosilicon carbohydrate macromers.

Immobilized lipase B from Candida antarctica (Novozyme 435) catalyzed the regioselective formation of ester bonds between organosilicon carboxylic diacids and a C1-O-alkylated sugar under mild reaction conditions (i.e., low temperature, neutral pH, solventless).

Enzyme-catalysed siloxane bond formation.

Biosilicification occurs on a globally vast scale under mild conditions. Although research has progressed in the area of silica biosynthesis, the molecular mechanisms of these interactions are effectively unknown. The natural production of silica in the Tethya aurantia marine sponge, Cylindrotheca fusiformis diatom, and Equisetum telmateia plant appear to be similar.
