A novel methodology for hydrogel water content determination by EPR: The basis for real-time monitoring of controlled drug release and hydrogel swelling and degradation

Polymer Testing, 2021
The hydrogel water content is of fundamental importance for controlled drug delivery, as it influences the overall hydrogel integrity and solubility, as well as the diffusion kinetics of substances.

Pulsed Dipolar EPR Spectroscopy and Metal Ions: Methodology and Biological Applications

ChemPlusChem, 2020
AbstractPulsed dipolar electron paramagnetic resonance spectroscopy (PDS) is a valuable method for determining biomolecular structures and their conformational changes during function. Often, this method is applied to paramagnetic metal ions that are either intrinsic co‐factors of biomolecules or introduced into biomolecules as spin labels.

Development of an EPR-based methodology to study protein-lipid interaction

Biophysical Chemistry
ABSTRACT The interaction of protein with other biomolecules is central to all cellular processes. In particular, protein-lipid interactions play an essential role in regulating soluble and membrane protein function, structure, and dynamics.

A Q-Band Pulse EPR/ENDOR Spectrometer and the Implementation of Advanced One- and Two-Dimensional Pulse EPR Methodology

Journal of Magnetic Resonance, 2001
A versatile high-power pulse Q-band EPR spectrometer operating at 34.5--35.5 GHz and in a temperature range of 4--300 K is described. The spectrometer allows one to perform one- and two-dimensional multifrequency pulse EPR and pulse ENDOR experiments, as well as continuous wave experiments.

Syntheses and Electrochemical and EPR Studies of Porphyrins Functionalized with Bulky Aromatic Amine Donors

Molecules, 2023
A series of nickel(II) porphyrins bearing one or two bulky nitrogen donors at the meso positions were prepared by using Ullmann methodology or more classical Buchwald–Hartwig amination reactions to create the new C-N bonds.

Distributions of molecular conformations and interactions revealed by EPR spectroscopy - methodology and application to hnRNPA1

, 2019
Proteins are long chains of peptide-bond linked amino acids, which have the fascinating ability to fold into a huge variety of three-dimensional shapes. To describe peptide sequences that have particularly large conformational flexibility, the umbrella terms intrinsically disordered domains (IDDs), resp. proteins (IDPs) have emerged.

Pulse EPR Detection of Lipid Exchange between Protein-Rich Raft and Bulk Domains in the Membrane: Methodology Development and Its Application to Studies of Influenza Viral Membrane [PDF]

Biophysical Journal, 2001
A pulse saturation-recovery electron paramagnetic resonance (EPR) method has been developed that allows estimation of the exchange rates of a spin-labeled lipid between the bulk domain and the protein-rich membrane domain, in which the rate of collision between the spin label and molecular oxygen is reduced (slow-oxygen transport domain, or SLOT domain)
