Measuring Photophysical Transition Rates with Fluorescence Correlation Spectroscopy and Antibunching
Publikováno v:
The Journal of Physical Chemistry Letters. 13:4823-4830
We present a new method that combines fluorescence correlation spectroscopy (FCS) on the microsecond time scale with fluorescence antibunching measurements on the nanosecond time scale for measuring photophysical rate constants of fluorescent molecul

Wide-field optical imaging of electrical charge and chemical reactions at the solid-liquid interface
Publikováno v:
Proceedings of the National Academy of Sciences USA
From molecules and particles to macroscopic surfaces immersed in fluids, chemical reactions often endow interfaces with electrical charge which in turn governs surface interactions and interfacial phenomena. The ability to measure the electrical prop
