摘要
We report a new, solid-state, integrated optical array sensor platform. The optical sensor array and integrated light source (OSAILS) is demonstrated for quenchometric O-2 detection. The OSAILS requires low voltages (3-5 V dc), it is stable (less than or equal to5% RSD over the course of several hours of continuous operation), it is reproducible and reversible (less than or equal to3% RSD), it exhibits a rapid response time (<30 s), and it provides good detection limits (0.2% O-2). The OSAILS opens the door to a number of new optical sensor array strategies.
