EPR spectroscopy as a tool in homogeneous catalysis research [PDF]

open access: yes, 2015
In the context of homogeneous catalysis, open-shell systems are often quite challenging to characterize. Nuclear magnetic resonance (NMR) spectroscopy is the most frequently applied tool to characterize organometallic compounds, but NMR spectra are ...

Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale

open access: yesAdvanced Optical Materials, EarlyView.
Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

open access: yesAdvanced Science, EarlyView.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

Electronic and Geometric Structures of Paramagnetic Diazadiene Complexes of Lithium and Sodium

open access: yesChemistryOpen, 2018
The electronic and molecular structures of the lithium and sodium complexes of 1,4‐bis(2,6‐diisopropylphenyl)‐2,3‐dimethyl‐1,4‐diazabutadiene (Me2DADDipp) were fully characterized by using a multi‐frequency electron paramagnetic resonance (EPR ...

How can EPR spectroscopy help to unravel molecular mechanisms of flavin-dependent photoreceptors?

open access: yesFrontiers in Molecular Biosciences, 2015
Electron paramagnetic resonance (EPR) spectroscopy is a well-established spectroscopic method for the examination of paramagnetic molecules. Proteins can contain paramagnetic moieties in form of stable cofactors, transiently formed intermediates, or spin

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

open access: yesAdvanced Science, EarlyView.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...
