Abstract

Quantitative and qualitative determination of metal ions is essential for a number of applications in life sciences and environmental monitoring. Optical and, namely, luminescent sensing allows non-invasive measurements within parallel monitoring of multiple samples. A wide variety of luminescent sensing probes using ion-sensitive indicators have been developed for sensing, imaging, and biomedical applications. Here we report a new sensitive element based on excitation energy transfer from donor (rhodamine 6G derivate) to acceptor (microalgae). The concepts and advantages of rhodamine-to-microalgae energy transfer-based sensor systems were highlighted.
