Summary:
- This article discusses a new type of optical sensor that can detect the presence and concentration of various gases, including carbon dioxide, methane, and ammonia.
- The sensor uses a unique design that combines a photonic crystal structure with a metal-organic framework material, allowing it to selectively detect and measure different gas molecules.
- The sensor has potential applications in environmental monitoring, industrial process control, and medical diagnostics, as it can provide real-time, accurate measurements of gas concentrations.
