The introduced fabrication route, based on mostly abundant organic precursors, is highly versatile as it facilitates the utilization of chemical functionalities of the primary ink by a simple one-step laser writing process. The well-defined morphology and chemical functionality of those sensor architectures may be tailored for other applications by changing/optimizing the vast process parameters including the selected precursor materials with their specific functionalities, the ink composition, the primary coating thickness, the substrate, the laser-treatment parameters, and the conversion environment. This renders the proposed concept feasible for the application in sensor array technologies in wearable, easy-to-operate, and real-time sensing devices.
