Watching the Photo-Oxidation of a Single Aromatic Hydrocarbon Molecule.
TLDR
The photooxidation of single dye molecules can be followed by confocal fluorescence microscopy and the self-sensitized reaction with singlet oxygen leads to a suite of products, which may be differentiated spectrally.Abstract:
The photooxidation of single dye molecules (see scheme) can be followed by confocal fluorescence microscopy. The self-sensitized reaction with singlet oxygen leads to a suite of products, which may be differentiated spectrally. Tentative structures for certain photoproducts have been obtained from quantum-chemical calculations.read more

Photophysics of Fluorescent Probes for Single-Molecule Biophysics and Super-Resolution Imaging
Taekjip Ha,Philip Tinnefeld +1 more
TL;DR: The thiol-induced blinking of Cy5, a curse for single-molecule biophysical studies that was later overcome using Trolox through a reducing/oxidizing system but a boon for super-resolution imaging owing to the controllable photoswitching, is reviewed.

Photobleaching of Rhodamine 6G in Poly(vinyl alcohol) at the Ensemble and Single-Molecule Levels
TL;DR: In this article, the photobleaching of rhodamine 6G (R6G) ensembles in polyvinyl alcohol (PVA) was investigated as a function of illumination time, excitation intensity, the presence of oxygen, and temperature.

Development and Testing of the OPLS All-Atom Force Field on Conformational Energetics and Properties of Organic Liquids
TL;DR: In this article, the parametrization and testing of the OPLS all-atom force field for organic molecules and peptides are described, and the parameters for both torsional and non-bonded energy properties have been derived, while the bond stretching and angle bending parameters have been adopted mostly from the AMBER force field.

Single-Molecule Enzymatic Dynamics
TL;DR: A molecular memory phenomenon, in which an enzymatic turnover was not independent of its previous turnovers because of a slow fluctuated of protein conformation, was evidenced by spontaneous spectral fluctuation of FAD.

Unmasking electronic energy transfer of conjugated polymers by suppression of O(2) quenching
Ji Yu,Dehong Hu,Paul F. Barbara +2 more
TL;DR: Time-resolved single-molecule data demonstrate that the 580-nanometer conformation exhibits a "landscape" for intramolecular electronic energy relaxation with a "funnel" that contains a 580- nanometer singlet exciton trap at the bottom.

Observation of individual chemical reactions in solution.
TL;DR: Discrete chemical reaction events occurring in solution have been observed by single photon detection of a bimolecular, chemiluminescent reaction from 9,10-diphenylanthracene in acetonitrile with potential pulses applied to an ultramicroelectrode.
