▪ Abstract Recent experimental and theoretical studies concerning single-molecule spectroscopy in solids are discussed. Pure quantum effects—such as photon bunching, antibunching, and spectral jumps—and more classical phenomena—such as near-field excitation, saturation, ac/dc Stark shifts, spectral diffusion, two-photon excitation, and customary ...

Combining single-molecule manipulation and single-molecule detection
Current Opinion in Structural Biology, 2014Single molecule force manipulation combined with fluorescence techniques offers much promise in revealing mechanistic details of biomolecular machinery. Here, we review force-fluorescence microscopy, which combines the best features of manipulation and detection techniques.

Single-Molecule Torsional Pendulum
Science, 2005We have built a torsional pendulum based on an individual single-walled carbon nanotube, which is used as a torsional spring and mechanical support for the moving part. The moving part can be rotated by an electric field, resulting in large but fully elastic torsional deformations of the nanotube.

Fluorescence resonance energy transfer (FRET) is a photophysical phenomenon that has been repurposed as a biophysical tool to measure nanometer distances. With FRET by DNA eXchange, or FRET X, many points of interest (POIs) in a single object can be probed, overcoming a major limitation of conventional single-molecule FRET.

Drug Discovery Today: Technologies, 2005
Single molecule technologies provide an alternative set of approaches to conventional techniques and promise to deliver fundamentally new information about biological processes at the level of molecular movement, dynamics and function. As several of these mature and become more accessible for routine use in molecular biology laboratories, the potential

Single-Molecule Optomechanical Cycle
Science, 2002Light-powered molecular machines are conjectured to be essential constituents of future nanoscale devices. As a model for such systems, we have synthesized a polymer of bistable photosensitive azobenzenes. Individual polymers were investigated by single-molecule force spectroscopy in combination with optical excitation in total internal reflection.

Single-molecule imaging is a powerful tool to understand workingmechanisms of glycoproteins and glycolipids in cell plasma membranes by overcoming intrinsically stochastic and inhomogeneous properties of biological molecular systems. Here, basic techniques for single-molecule imaging microscopy are described.

Imaging single-molecule dichroism
Optics Letters, 1997Video-enhanced optical fluorescence microscopy has been used to determine the direction of the transition dipole moment of individual molecules. Fast electro-optical switching of the polarization of the excitation allowed us to detect the linear dichroism of single fluorophores in solid phospholipid membranes.

Oligoyne Single Molecule Wires
Journal of the American Chemical Society, 2009We report the electrical conductance at the single molecule level of the oligoyne molecular wires Py-(C[triple bond]C)(n)-Py (n = 1, 2 and 4; Py = 4-pyridyl) using STM-molecular break junction techniques in Au|molecule|Au configurations. The conductance histograms reveal multiple series of peaks attributed to differing contact geometries between the ...
