OPTICAL SENSOR FOR ANALYZING BIOLOGICAL AGENTS AND METHOD OF ITS MANUFACTURE

The invention refers to an optical microsensor (201, 301) for interpretation of characteristics of biological agents and for identification of a biological agent in a fluidic environment using spectral changes of whispering gallery modes and/ or changes of a fluorescence spectrum depending on the biological agent to be identified. The sensor (201, 301) comprises an array of sensor cells (2b) formed by a plurality of wells (5b) within a frame structure (3b) arranged on a glass substrate (4b). The frame structure (3b) is covered by a glass plate (4c) so that each sensor cell (2b) is bordered to every side, and each sensor cell (2b) comprises at least one optical microresonator (6b) each of which having a predetermined size, shape and position with regard to the cell borders (7a, 7b) of the respective well (5b). Furthermore, the microresonators (6b) are additively manufactured from photosensitive polymer material. The invention also refers to a method of manufacturing the optical sensor (201, 301) as well as a method of use of the optical sensor (201, 301).
