ACS Nano 13 , 6947–6954 (2019).Biophysical Techniques for Characterization of Cells. M. Heilemann, in Comprehensive Biophysics, 2012 Abstract. Fluorescence microscopy is a valuable toolbox to study cellular structures and dynamics spanning scales from the single molecule to the live animal. The spatial resolution that can be achieved with any light-based microscopy is however limited to about …Single-molecule localization microscopy (SMLM) is one of the most widespread of these methods and owes its success in large part to the ability to control …Photosynthesis begins when a network of pigment–protein complexes captures solar energy and transports it to the reaction center, where charge separation occurs. When necessary (under low light conditions), photosynthetic organisms perform this energy transport and charge separation with near unity quantum efficiency. Remarkably, this high efficiency is maintained under physiological ...

These fluorophores emit light upon laser excitation, but by conventional means, background fluorescence can interfere with the desired fluorescent signal. In order to improve the signal-to-background ratio, total internal reflection fluorescence microscopy (TIRFM) was developed here at the University of Michigan by Daniel Axelrod. A single-molecule chemical reaction studied by high-resolution atomic force microscopy and scanning tunneling microscopy induced light emission. ACS Nano 13 , 6947–6954 (2019).Single-molecule fluorescence microscopy was used to quantify ruthenium-promoted allylcarbamate cleavage reactions in live A549 human lung cells. Individual turn-on events were detected as single fluorescence spots and found to occur more frequently in the mitochondria than the rest of the cell. These results suggest that the subcellular ...
