Highly flexible, robust, and sensitive Infrared nanosensors were fabricated based on carbon nanoparticles that were synthesized through a simple and low-cost flame method. The infrared nanosensor devices showed sharp infrared photoresponse with a response time of similar to 68 ms and a maximum photocurrent change of similar to 52.9%. The devices showed a superhydrophobic property with a contact angle larger than 150 degrees and a sliding angle of similar to 4 degrees. The mechanism for the enhanced Infrared photoresponse from carbon nanoparticles is discussed.
