Photonic crystal cavities made from poly(methyl methacrylate) (PMMA), which swells when it comes into contact with gases, have enabled researchers at MIT’s Quantum Photonics Laboratory to develop extremely sensitive and compact optical sensors that can detect minute amounts of target molecules. The PMMA can be treated to interact with various target chemicals, making the sensors suitable for a range of applications from antibody detection in medical applications to the sensing of toxic gases for homeland security purposes.
