Investigations of excitation energy transfer and intramolecular interactions in a nitrogen corded distrylbenzene dendrimer system. [PDF]

, 2002
The photophysics of an amino-styrylbenzene dendrimer (A-DSB) system is probed by time-resolved and steady state luminescence spectroscopy. For two different generations of this dendrimer, steady state absorption, emission, and photoluminescence ...

A multi-functional imaging approach to high-content protein interaction screening.

PLoS ONE, 2012
Functional imaging can provide a level of quantification that is not possible in what might be termed traditional high-content screening. This is due to the fact that the current state-of-the-art high-content screening systems take the approach of ...

Determination of Fluorescence Polarization and Absorption Anisotropy in Molecular Complexes Having Threefold Rotational Symmetry [PDF]

, 2008
The current work concerns investigation of the polarization properties of complex molecular ensembles exhibiting threefold (C3) rotational symmetry, particularly with regard to the interplay between their structure and dynamics of internal energy ...

Eliminating Stripe Artifacts in Light-Sheet Fluorescence Imaging [PDF]

Review of Scientific Instruments 89, 036107 (2018), 2017
We report two techniques to mitigate stripe artifacts in light-sheet fluorescence imaging. The first uses an image processing algorithm called the multidirectional stripe remover (MDSR) method to filter stripes from an existing image. The second uses an elliptical holographic diffuser (EHD) with strong scattering anisotropy to prevent stripe formation ...

Sensing ligand binding to a clinically relevant lectin by tryptophan fluorescence anisotropy [PDF]

, 2011
Increasing insights into the involvement of endogenous lectins in disease processes fuel the interest to develop potent inhibitors. As a consequence, robust assay procedures are required. Due to their activity as adhesion/growth-regulatory effectors this

Laser-controlled fluorescence in two-level systems [PDF]

, 2010
The ability to modify the character of fluorescent emission by a laser-controlled, optically nonlinear process has recently been shown theoretically feasible, and several possible applications have already been identified.

Anionic Phospholipids Shift the Conformational Equilibrium of the Selectivity Filter in the KcsA Channel to the Conductive Conformation: Predicted Consequences on Inactivation

Biomedicines, 2023
Here, we report an allosteric effect of an anionic phospholipid on a model K+ channel, KcsA. The anionic lipid in mixed detergent–lipid micelles specifically induces a change in the conformational equilibrium of the channel selectivity filter (SF) only ...

Angle-resolved polarimetry measurements of antenna-mediated fluorescence [PDF]

Phys. Rev. Applied 4, 054014 (2015), 2015
Optical phase-array antennas can be used to control not only the angular distribution but also the polarization of fluorescence from quantum emitters. The emission pattern of the resulting system is determined by the properties of the antenna, the properties of the emitters and the strength of the antenna-emitter coupling.

Tryptophan-containing proteins as label-free nanothermometers [PDF]

arXiv, 2021
There remains a need for techniques to monitor thermal processes at high spatiotemporal resolution, with myriad potential applications in chemistry, biology, and engineering. Measurement of temperature from nanoscale molecular phenomena are particularly promising due to their general compatibility with biological systems.

Picosecond time-resolved energy transfer within C-phycocyanin aggregates of Mastigocladus laminosus [PDF]

, 1988
We have investigated by picosecond absorption experiments how the size of C-phycocyanin aggregates from Mastigocladus laminosus influences the excitation energy transfer kinetics.
