Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
Ryder, Alan G.; Power, Sarah; Glynn, Thomas J. (2003)We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ... -
Fluorescence lifetime based pH sensing using Resorufin
Ryder, Alan G.; Power, Sarah; Glynn, Thomas J. (2003)Accurate, non-contact pH sensing is of particular importance in the biological and clinical sciences. Fluorescence lifetime based pH sensing is potentially more useful than intensity based methods because of the reduced ... -
Time-domain measurement of fluorescence lifetime variation with pH
Ryder, Alan G.; Morrison, John J.; Power, Sarah; Glynn, Thomas J. (Society of Photo-optical Instrumentation Engineers, 2001)Advances in the design and miniaturization of the lasers and electronics required for Time Correlated Single Photon Counting (TCSPC) measurement of fluorescence lifetime have simplified the use of the time domain method. ...
