Investigation of Nano-Environment

FLIM identifies environmental changes, both spatially and temporally resolved.

A GFP fusion protein was expressed in living cells that localizes to different cellular structures. Subcellular localization of this GFP fusion protein gives rise to two protein populations.

Each population exhibits a different average lifetime as revealed by the lifetime changes with localization to different organelles (yellow and red lines).
