Assessment of cellular actin dynamics by measurement of fluorescence anisotropy

To study cellular actin dynamics, a cell-free assay based on fluorescence anisotropy was developed. Using G-actin-Alexa as a probe, we found that anisotropy enhancement reflects F-actin elongation. Anisotropy enhancement varies with the…

Photophysics of a series of efficient fluorescent pH probes for dual-emission-wavelength measurements in aqueous solutions

This paper evaluates the 5-aryl-2-pyridyloxazole backbone to engineer donor-acceptor fluorescent pH probes after one- or two-photon absorption. Parent fluorophores, as well as derivatives that can be used to label biomolecules, can be easily…

Electrochemical and spectroscopic characterization of organic compound uptake in silica core-shell nanocapsules

Oil-filled silica nanocapsules consisting of a hydrophobic liquid core and a silicate shell have been shown to efficiently extract hydrophobic compounds from aqueous media. With a view toward quantifying the selectivity of these systems, a series of…
