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 ...

Synthesis of some polymerisable fluorescent dyes

open access: yes, 2002
The preparation of some fluorescent polymerisable dyes and brighteners derived from 4-subsituted N-alkyl-1,8-naphthalimide are presented. Each of the dyes were copolymerised with styrene giving coloured fluorescent polymers that were stable to solvent ...

Switchable fluorescence by click reaction of a novel azidocarbazole dye† [PDF]

open access: yesRSC Advances, 2014
Imaging is – even these days – still restricted to of a few classes of robust dyes. A demand for switchable tags led us to the design of a new class of pre-fluorophores.

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 ...

Novel Fluorescent Dyes for Single DNA Molecule Techniques

open access: yesMolecular Imaging, 2013
To answer the demands of scientific and medical imaging issues, the family of nucleic acid fluorescent dyes is constantly enlarging. Most of the developed dyes reveal high qualities in bulk solution assays but are inefficient to produce a strong and ...

A novel photoacoustic-fluorescent contrast agent for quantitative imaging of lymphatic drainage

open access: yesPhotoacoustics, 2021
In vivo near-infrared (NIR) photoacoustic imaging (PAI) studies using novel contrast agents require validation, often via fluorescence imaging. Bioconjugation of NIR dyes to proteins is a versatile platform to obtain contrast agents for specific ...
