Epub 2016 Aug 29.Light upconversion is a very powerful tool in bioimaging as it can eliminate autofluorescence, increase imaging contrast, reduce irradiation damage, and increase excitation penetration depth in vivo. In particular, triplet-triplet annihilation upconverting (TTA-UC) nanoparticles and liposomes offer high upconversion efficiency at low excitation power. However, TTA-UC is quenched in air by oxygen, w ... Read More
