Abstract :
This work proposes a novel method for quantitative imaging of radioactivity on microfluidic chips by using visible light emission from Čerenkov radiation. Čerenkov radiation is generated when charged particles travel through an optically transparent material with a velocity greater than that of light in that material. It has been observed at UCLA that microfluidic chips used for 18F-related radio-synthesis studies have shown unidentified visible light emissions. In this study, the origin of the light was investigated and its feasibility as a quantitative imaging source was tested.
