Single-molecule fluorescence spectroscopy in (bio)catalysis

Single-molecule fluorescence spectroscopy in (bio)catalysis.

The ever-improving time and space resolution and molecular detection sensitivity of fluorescence microscopy offer unique opportunities to deepen our insights into the function of chemical and biological catalysts. Because single-molecule microscopy allows for counting the turnover events one by one, one can map the distribution of the catalytic activities of different sites in solid heterogeneo...

Single-molecule fluorescence spectroscopy of protein folding.

Single-molecule spectroscopy is an important new approach for studying the intrinsically heterogeneous process of protein folding. This Review illustrates how different single-molecule fluorescence techniques have improved our understanding of mechanistic aspects in protein folding, exemplified by a series of recent experiments on a small protein.

Single-molecule fluorescence spectroscopy and imaging

Observability of individual fluorescent molecules under a microscope has many applications in biology.1, 2 In particular, by grafting fluorophores to biomolecules, they can be tracked in real time in live cells for monitoring of their conformational changes and interactions with other molecules. In other words, singlemolecule imaging allows scientists to read the textbook of life pretty much as...

Single-molecule fluorescence spectroscopy using phospholipid bilayer nanodiscs.

Nanodiscs are a new class of model membranes that are being used to solubilize and study a range of integral membrane proteins and membrane-associated proteins. Unlike other model membranes, the Nanodisc bilayer is bounded by a scaffold protein coat that confers enhanced stability and a narrow particle size distribution. The bilayer diameter can be precisely controlled by changing the diameter ...
