Abstract
Using time-gated fluorescence lifetime imaging microscopy, significantly more signals from 3,6-bis(1-methyl-2-vinyl-pyridinium) carbazole diiodide (o-BMVC) foci, characterized by the longer fluorescent decay time of o-BMVC, were detected in six types of cancer cells than in three types of normal cells. Accumulating evidence suggested that the o-BMVC foci are mainly the G-quadruplex foci. The large contrast in the number of o-BMVC foci can be considered as a common signature to distinguish cancer cells from normal cells. Further study of tissue biopsy showed that the o-BMVC test provides a high accuracy for clinical detection of head and neck cancers. ? 2018, The Author(s).
