A Study on the Structure, Optical Properties and Cellular Localization of Novel 1,3-Benzothiazole-Substituted BODIPYs

open access: yesColorants, 2023
A library of seven novel 1,3-benzothiazole-substituted BODIPY derivatives with tunable optical properties was synthesized. The new fluorescent dyes exhibited bathochromically shifted absorptions (up to 670 nm) and emissions centered in the red and near ...

Evaluation of the diet of a carabid predator using fluorescent marking of prey

open access: yesEuropean Journal of Entomology, 2015
We present a UV-fluorescent dye-based prey marking technique, using three different dyes, with later detection of the dyes in the guts of predators using a micro-plate fluorescent reader.

Label-free and sensitive fluorescent detection of sequence-specific single-strand DNA based on S1 nuclease cleavage effects. [PDF]

open access: yesPLoS ONE, 2014
The ability to detect sequence-specific single-strand DNA (ssDNA) in complex, contaminant-ridden samples, using a fluorescent method directly without a DNA extraction and PCR step could simplify the detection of pathogens in the field and in the clinic ...

Comparison of the new OPS Imaging technique with intravital microscopy: Analysis of the colon microcirculation [PDF]

open access: yes, 2002
Background. The OPS imaging technique has been introduced for in vivo assessment of microcirculation in humans. The aim of this study was to validate the new technique against intravital fluorescence microscopy (IFM) for the visualization of colon ...

A beta-herpesvirus with fluorescent capsids to study transport in living cells. [PDF]

open access: yes, 2012
Fluorescent tagging of viral particles by genetic means enables the study of virus dynamics in living cells. However, the study of beta-herpesvirus entry and morphogenesis by this method is currently limited.

3D visualization of additive occlusion and tunable full-spectrum fluorescence in calcite

open access: yesNature Communications, 2016
Introducing organic guests to a crystal is a convenient way to tailor its properties. Here, the authors occlude fluorescent dyes within calcite to reveal that additives can occupy distinct zones of a crystal, and strategically embed green, blue, and red ...
