Patent ID: 8067249

Claim:
A method for functionalizing a biosensor, comprising: providing a substrate, including at least one sensor field arranged thereon: applying a photoresist layer over an entire surface of the substrate and then photolithographically patterning the photoresist layer using a photomask with a set pattern, so that a patterned layer is formed, to form a corresponding cavity above the sensor filed; applying capture molecules to the sensor field, so that the capture molecules are immobilized within the cavity above the sensor filed, wherein prior to the application of capture molecules, a carrier layer based on hydrogel is applied to the sensor field, wherein the application of capture molecules the sensor field is carried out simultaneously with the application of a carrier layer based on hydrogel to the sensor field, and wherein the application of capture molecules is followed by application of an encapsulation layer based on hydrogel; and mounting a wafer, functionalized in such a manner following the application of capture molecules in upside-down mode to a sawing sheet, tensioned in a sawing frame, and sawing individual chips out of the wafer.
