Exploring the Interactions of Ruthenium (II) Carbosilane Metallodendrimers and Precursors with Model Cell Membranes through a Dual Spin-Label Spin-Probe Technique Using EPR [PDF]

open access: yesBiomolecules, 2019
Dendrimers exhibit unique interactions with cell membranes, arising from their nanometric size and high surface area. To a great extent, these interactions define their biological activity and can be reported in situ by spin-labelling techniques.

A quantum spin-probe molecular microscope [PDF]

open access: yesNature Communications, 2016
Single spin defects can allow high-resolution sensing of molecules under an applied magnetic field. Here, the authors propose a protocol for three-dimensional magnetic resonance imaging with angstrom-level resolution exploiting the dipolar field of a ...

Tuning the nuclei-induced spin relaxation of localized electrons by the quantum Zeno and anti-Zeno effects

open access: yesPhysical Review Research, 2023
Quantum measurement back action is fundamentally unavoidable when manipulating electron spins. Here we demonstrate that this back action can be efficiently exploited to tune the spin relaxation of localized electrons induced by the hyperfine interaction.

Novel Orientation-Sensitive Spin Probes for Graphene Oxide Membranes Study

open access: yesMembranes, 2022
Spin probe EPR spectroscopy is currently the only method to quantitatively report on the orientational ordering of graphene oxide membranes. This technique is based on the analysis of EPR spectra of a membrane containing stable radicals sorbed on ...

Topological nonlinear optics with spin-orbit coupled Bose-Einstein condensate in cavity

open access: yesnpj Quantum Information, 2022
We investigate topological nonlinear optics with spin-orbit coupled Bose-Einstein condensate in a cavity. The cavity is driven by a pump laser and a weak probe laser.

Coupling of phagocytic NADPH oxidase activity and mitochondrial superoxide production

open access: yesFrontiers in Cardiovascular Medicine, 2022
Superoxide radical plays an important role in redox cell signaling and physiological processes; however, overproduction of superoxide or insufficient activity of antioxidants leads to oxidative stress and contributes to the development of pathological ...

Sensitivity of a collisional single-atom spin probe

open access: yesSciPost Physics Core, 2023
We study the sensitivity of a collisional single-atom probe for ultracold gases. Inelastic spin-exchange collisions map information about the gas temperature $T$ or external magnetic field $B$ onto the quantum spin-population of single-atom probes, and ...
