Abstract
A sensor and sensing array are disclosed. These devices include one or more fluorescent polymers selected to register one or more analytes. These analytes may include various metal ions or volatile organic compounds. The sensor and sensing array are responsive to excitation light to emit fluorescence responses indicative of the analytes. In particular, the sensing array may provide a pattern of responses operable as a “chemical nose” to identify one or more of the analytes. Techniques for using and making the sensor and sensing array are also disclosed.
