Nature Nanotechnology, 2017
Mass and electrical charge are fundamental properties of biological macromolecules. Although molecular mass has long been determined with atomic precision, a direct and precise determination of molecular charge remains an outstanding challenge. Here we report high-precision (<1e) measurements of the electrical charge of molecules such as nucleic ...

Physical Review Letters, 2004
For solving the atomic structure of organic molecules such as small proteins which are difficult to crystallize, the use of a jet of doped liquid helium droplets traversing a continuous high energy electron beam is proposed as a means of obtaining electron diffraction patterns (serial crystallography).

Current Opinion in Structural Biology, 2003
Recent developments in fluorescence and force spectroscopy enable us to go beyond the ensemble average and measure the behavior of individual biomacromolecules. These single-molecule approaches can directly resolve transient intermediate states and multiple reaction pathways, and thus are uniquely powerful in characterizing the complex dynamics of ...

The dielectric nanoparties/molecules in the vicinity of a WGM microcavity evanescently perturb the WGM field. Owing to the tiny mode volume and high quality factor of the microcavity, the resulting resonance shift and spectral broadening of the microcavity’s transmission spectrum can be read out with a high enough signal-to-noise ratio.

Single-Molecule Optoelectronics
Accounts of Chemical Research, 2004With discrete states, several-atom Ag(n) nanoclusters exhibit molecule-like behavior with strong visible fluorescence and robust optical properties. This new class of single-molecule fluorophores has been created and electrically contacted in thin films to produce the first electroluminescent single molecules.

Single-Molecule Mechanoenzymatics
Annual Review of Biophysics, 2012The ability of cellular signaling networks to sense, process, and respond to internal and external stimuli relies on their specific detection and transduction based on molecular recognition. The molecular mechanisms by which force is specifically sensed by mechanoenzymatic processes, translated into biochemical signals, and wired to cellular signaling

Annual Review of Physical Chemistry, 2004
▪ Abstract We review recent developments in single-molecule spectroscopy and microscopy. New optical methods provide access to the absorption, emission, or excitation spectra of single nano-objects and can determine either the positions of these objects with subwavelength accuracy or the full three-dimensional orientation of their transition dipole ...
