A Compact and Sensitive Time-Resolved-Optical-Reader for Bioassay Using Low-Energy Excitable and Long-Lived-Fluorescence Nanolabels.

Time-resolved fluorescence measurement, a technique utilized to improve sensitivity for fluorescence detection, is becoming more accessible due to the recent development of bright nanolabels with long fluorescence lifetimes and low-energy excitation. Currently, instruments taking advantage of this technique for broader applications (in-field or point-of-care testing) are lagging behind in their development. In this work, a low-cost, compact, and sensitive time-resolved-optical-reader was developed aiming to advance such a technique for wider applications.
