The Cellular and Organismal Effects of Nitroxides and Nitroxide-Containing Nanoparticles

International Journal of Molecular Sciences
Nitroxides are stable free radicals that have antioxidant properties. They react with many types of radicals, including alkyl and peroxyl radicals. They act as mimics of superoxide dismutase and stimulate the catalase activity of hemoproteins. In some situations, they may exhibit pro-oxidant activity, mainly due to the formation of oxoammonium cations ...

PERFECTA Loaded Lipid Cubosomes for 19F‐MRI: Physico‐Chemical Characterization

Chemistry – A European Journal, EarlyView.
Phytantriol‐based cubosomes loaded with PERFCTA, a fluorinated MRI probe, were developed as promising systems for imaging and drug delivery. The nanoparticles showed high PERFECTA encapsulation efficiency, strong fluorine MRI signals, and optimal colloidal stability in biological media.

Interplay of Bridge Topology and Conformation in Phenylene‐Bridged Trityl Diradicals

Chemistry – A European Journal, EarlyView.
We present a meta‐phenylene‐bridged trityl diradical that exhibits an unexpectedly weak antiferromagnetic exchange coupling J with a strong environment‐dependent magnitude. Combined VSM, EPR, DFT, and MD studies reveal that structural flexibility modulates σ‐, π‐, and through‐space exchange contributions, highlighting the crucial role of geometry in ...

Embedding a Dinuclear Ru─Pt Photocatalyst Into Polyampholytic Graft Copolymer Matrix Enables Prolonged Hydrogen Evolution While Allowing Catalyst Repair

Chemistry – A European Journal, EarlyView.
A unimolecular polyampholytic graft copolymer matrix provides a protective confinement for an electrostatically embedded tetrapyridophenazine‐bridged heterodinuclear Ru‐Pt hydrogen evolving photocatalyst. The matrix slows the degradation kinetics of the catalyst and at the same time does not hinder its repair by ammonium persulfate.
