Optical studies of individual molecules at low and room temperature can provide information
about the dynamics of local environments in solids, liquids and biological systems …

Owing to the size mismatch between light and nanoscale objects such as single molecules,
it is important to be able to control light–molecule interactions 1 , 2 , 3 , 4 . Plasmonic …

Using two different double-modulation techniques, we have observed the optical-absorption
spectrum of single dopant molecules of pentacene in a p-terphenyl host crystal at liquid-…

Optical spectroscopy at the ultimate limit of a single molecule has grown over the past
dozen years into a powerful technique for exploring the individual nanoscale behavior of …

We demonstrate single-molecule fluorescence imaging beyond the optical diffraction limit in
3 dimensions with a wide-field microscope that exhibits a double-helix point spread function …

… materials) in 1994 by Moerner and co-workers … we discuss the evolution of a phenomenological
model describing the space-charge field formation in PR polymers, and in section 3.2 we …

Efficient collection and detection of fluorescence coupled with careful minimization of
background from impurities and Raman scattering now enable routine optical microscopy and …

The generation of non-classical states of light 1 is of fundamental scientific and technological
interest. For example, ‘squeezed’ states 2 enable measurements to be performed at lower …

Optical imaging and analysis of single molecules continue to unfold as powerful ways to
study the individual behavior of biological systems, unobscured by ensemble averaging. …

… In thought-experiments we sometimes assume that we do; this invariably entails ridiculous
… is fair to state that we are not experimenting with single particles, any more than we can raise …
