As new functional materials,porous silicon （PS）and porous silicon microcavity （PSM）have performance in biosensors fabrication for many good properties, such as light-induced t perfect , microelectronics compatibility, filtration ability, controllable growth of nano-micro holes. Many biosensors based on porous silicon and porous silicon microcavity have been fabricated, and applied in rapid detections of blood, bacteria,virus,DNA, etc. The structure and properties of PS and PSM are analyzed. The research status of the biosensors based on PS and PSM are introduced. At the same time, it is believed that the exploiting micro-chip, integration and product-forming are expected to be the development trend.
