Some embodiments presented here relate to chemical sensors with enhanced sensitivity and selectivity. In an embodiment, the sensor is a composite thin film that comprises (e.g., is made of) chemically-modified carbon black and a chemically-sensitive polymer base. By grafting gold nanoparticles on carbon black, the number of binding sites on the sensor thin film is increased, thereby increasing the sensitivity. Furthermore, ligand attached gold nanoparticles are grafted on carbon black to increase the binding sites on the sensor thin film in some embodiments, which results in increased sensitivity as well as improved selectivity in some cases.
