Differential Downregulation of β1‐Adrenergic Receptor Signaling in the Heart

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Chronic sympathetic stimulation drives desensitization and downregulation of β1 adrenergic receptor (β1AR) in heart failure. We aim to explore the differential downregulation subcellular pools of β1AR signaling in the heart.

Fluorescence properties of self assembled colloidal supraparticles from CdSe/CdS/ZnS nanocrystals

open access: yesNew Journal of Physics, 2020
We first report the synthesis of supraparticles with a mean diameter of 130 nm consisting in a compact self-assembly of colloidal CdSe/CdS/ZnS nanocrystals encapsulated in a silica shell.

Optically controlled resonance energy transfer:Mechanism and configuration for all-optical switching [PDF]

open access: yes, 2008
In a molecular system of energy donors and acceptors, resonance energy transfer is the primary mechanism by means of which electronic energy is redistributed between molecules, following the excitation of a donor. Given a suitable geometric configuration

Mapping Charge Interactions in Intrinsically Disordered Proteins

open access: yesAdvanced Science, EarlyView.
This study presents analytical models to predict intrachain distances in intrinsically disordered proteins (IDPs), accounting for charge patterning, salt concentration, and electrostatic effects. Validated against single‐molecule FRET data, a minimal‐parameter polymer model is identified that captures key interactions and chain dimensions. These models

Benzoyl‐Xanthenoxanthenes: Versatile Chromophores for Light‐Engaging Applications

open access: yesAngewandte Chemie, EarlyView.
Oxidatively stable benzoyl‐fused peri‐xanthenoxanthene ribbons with NIR emission were synthesized. Their good spectral overlap enabled cascaded Förster resonance energy transfer (FRET) antennae in a nematic liquid crystal phase, achieving directional energy transfer.

Alkylthienyl Side Groups in Conjugated Polymers Enable Localization of π Electron Density and Facilitate Efficient Hole Transfer

open access: yesAdvanced Science, EarlyView.
Resonance Raman spectroscopy is used in combination with other spectroscopic and morphology characterization techniques to unveil the mechanistic origin of the shift in synthetic strategy to alkylthienyl peripheral groups for high‐performing organic photovoltaics.

Step size of the rotary proton motor in single FoF1-ATP synthase from a thermoalkaliphilic bacterium by DCO-ALEX FRET

open access: yes, 2012
Thermophilic enzymes can operate at higher temperatures but show reduced activities at room temperature. They are in general more stable during preparation and, accordingly, are considered to be more rigid in structure.
