The invention belongs to a micro-biosensor and particularly relates to a manufacturing method of a silica-based integratable micro-glucose sensor. The existing glucose sensor takes a glucose oxidase electrode as a device for molecular recognition and signal conversion, thus having poor stability and restricting the application of the glucose sensor on the basis of enzyme. The manufacturing method comprises the following steps of: manufacturing a silicon micro-channel by using a P-typed single-side polishing silicon wafer through electrochemical etching; depositing the silicon micro-channel in eletroplating solution without electricity at the temperature of 80 DEG C for 30-45 minutes; and taking out and washing the silicon micro-channel with deionized water, and obtaining the silica-based integratable micro-glucose sensor. The invention has the advantages that: the electrochemical process is adopted, the cost is low, and the operation is simple; the micro-channel has even porosity, and the ratio of the specific surface area to the depth is big; the eletroplating solution without electricity has simple preparation and low price; no influence on the glucose test is generated; three-dimensional structure is beneficial to the contact between the glucose and active substances, and the improvement of the oxidation current; and the micro-biosensor is beneficial to the exchange reaction of ions and is miniaturized and integrated, thus being beneficial to large-scale production.
