摘要：Biomaterial, for example bioactive silicon, may be fabricated by anodizing asilicon wafer to produce a wafer having a porous silicon region. In vitro experiments haveshown that certain types of porous silicon cause the deposition of apatite deposits bothon the porous silicon and neighboring areas of bulk silicon when immersed in a simulatedbody fluid solution. This deposition of apatite provides an indication that porous silicon ofappropriate form is bioactive, and therefore also biocompatible. A form of porous siliconis dissolved in the simulated body fluid solution and this is an indication of a resorbablebiomaterial characteristic. In addition to porous silicon, certain types of polycrystallinesilicon exhibit bioactive characteristics. Bioactive silicon may be used in the fabrication ofbiosensors for in vitro or in vivo applications. The bioactivity of the bioactive silicon maybe controlled by the application of an electrical potential thereto.
