High-Speed Tracking of Murine Cardiac Stem Cells
by Harmonic Nanodoublers

In
this work, PEG-stabilized potassium niobate nanocrystals (obtained by
grinding a large crystal) were used as second-harmonic emitters
(frequency-doubled light) to study the evolution of murine cardiac stem
cells. There's no photobleaching or blinking, and the excitation can be
done at a range of wavelength from 400 to 1550 nm.
