首次研究了多孔硅作为在水溶液中工作的电位生物传感器的衬底材料。采用标准的阳极蚀刻工艺，在不同掺杂的硅衬底上制备多孔硅。氧化后，对青霉素敏感的青霉素酶通过物理吸附与多孔结构结合。为了表征青霉素生物传感器的电化学性能，对这些场效应结构进行了电容-电压（C - V）测量。
For the first time porous silicon has been investigated for the purpose of application as a substrate material for potentiometric biosensors operating in aqueous solutions. Porous silicon was prepared from differently doped silicon substrates by a standard anodic etching process. After oxidation, penicillinase, an enzyme sensitive to penicillin, was bound to the porous structure by physical adsorption. To characterize the electrochemical properties of the so build up penicillin biosensor, capacitance - voltage (C - V) measurements were performed on these field-effect structures.
