Publication number: 20040052867Abstract: Biomaterial, for example bioactive silicon, may be fabricated by anodizing a silicon wafer to produce a wafer having a porous silicon region. In vitro experiments have shown that certain types of porous silicon cause the deposition of apatite deposits both on the porous silicon and neighboring areas of bulk silicon when immersed in a simulated body fluid solution. This deposition of apatite provides an indication that porous silicon of appropriate form is bioactive, and therefore also biocompatible. A form of porous silicon is dissolved in the simulated body fluid solution and this is an indication of a resorbable biomaterial characteristic. In addition to porous silicon, certain types of polycrystalline silicon exhibit bioactive characteristics. Bioactive silicon may be used in the fabrication of biosensors for in vitro or in vivo applications.

Patent number: 6541041Abstract: Crude drug extracts containing soluble silicon compounds as an effective component are obtained by subjecting a crude drug to extraction with water or an aqueous solvent, preferably at an alkaline pH. The crude drugs subjected to extraction to obtain the extracts may be derived from animals, plants, etc. The quality of the crude drug extract can be standardized using the soluble silicon compounds as an index. The soluble silicon compounds exhibit inhibitory action towards the production of plasma kallikrein. The amount of soluble silicon compounds in the dry extract may be used as an index whereby the quality of various crude drugs can be standardized which contributes to providing crude drug extracts having a stable or consistent quality. Consequently, the present invention greatly contributes to the appropriate standardization of pharmaceuticals.Type: GrantFiled: January 27, 2000Date of Patent: April 1, 2003Assignee: Nippon Zoki Pharmaceutical Co., Ltd.Inventor: Jin-emon Konishi
