Abstract: A biosensor is for sensing analytes in a fluid. The biosensor may include a first structural layer having a first hydrogel, a second structural layer having a second hydrogel, and a bioactive region extending between the first structural layer and the second structural layer and having a third hydrogel. The biosensor may include a first electrode coupled to the bioactive region, and a second electrode coupled to the first structural layer and being spaced apart from the bioactive region. The second structural layer may have a through opening adjacent the bioactive region, and the bioactive region may be configured to be in fluid communication with an environment external to the biosensor for receiving the fluid comprising the analytes.
