In this work, fluorescence correlation spectroscopy (FCS) was used to investigate the effects of potassium iodide (KI) on the electronic-state population kinetics of a range of organic dyes in the visible wavelength range. Apart from a heavy atom eff

Proton transport across biological membranes is a key step of the energy conservation machinery in living organisms, and it has been proposed that the membrane itself plays an important role in this process. In the present study we have investigated

Cellular processes such as nerve conduction, energy metabolism, and import of nutrients into cells all depend on transport of ions across biological membranes through specialized membrane-spanning proteins. Understanding these processes at a molecula

We report on label-free volume, concentration, and mobility analysis of single protein molecules and nanoparticles during their diffusion through a subattoliter detection volume, confined by a 100 nm aperture in a thin gold film. A high concentration

A central goal in bioanalytics is to determine the concentration of and interactions between biomolecules. Nanotechnology allows performing such analyses in a highly parallel, low-cost, and miniaturized fashion. Here we report on label-free volume, c

For a spatially restricted excitation volume, the effective modulation of the excitation in time is influenced by the passage times of the molecules through the excitation volume. By applying an additional time-modulated excitation, the buildup of ph

Proton-transfer reactions across and at the surface of biological membranes are central for maintaining the transmembrane proton electrochemical gradients involved in cellular energy conversion. In this study, fluorescence correlation spectroscopy wa

Fluorescence fluctuation analysis of individual pH-sensitive fluorophores has recently proven to be a useful approach for biomolecular proton exchange studies. In this work, dual-color fluorescence cross-correlation spectroscopy (FCCS) is demonstrate

Photoinduced transient dark states are exhibited by practically all common fluorophores. However, their information content has to date only been sparsely exploited due to methodological constraints. Here, a new concept is presented and verified that
