The present invention relates to sensors comprising pattern illumination-based annealed coated substrate and one or more functional molecules and process of using same. Such process yields components that can have one or more electronic and/or optical functionalities that are integrated on the same substrate or film and to which one or more functional molecules can be attached to yield a sensor. In addition, such process does not require large-scale clean rooms and is easily configurable. Thus, rapid device prototyping, design change and evolution in the lab and on the production side is realized. The resulting sensors provide a sensing capability that is as good as or better than current sensors and can be tailored to sense specific biomaterials and/or chemicals.
