Aminoxyl-containing radical spin labeling in polymers and copolymers
TL;DR: Aminoxyl-containing radical is provided in polymers and copolymers by replacing a hydroxyl moiety in a carboxyl group at the chain end of a starting material biodegradable polymer or copolymer with imino or oxy linked to aminoxylcontaining radical to form an amide linkage or an oxycarbonyl linkage at the end of biocompatible polymers as mentioned in this paper.

The Lipid-binding Domain of Wild Type and Mutant α-Synuclein: COMPACTNESS AND INTERCONVERSION BETWEEN THE BROKEN AND EXTENDED HELIX FORMS*
TL;DR: Using pulsed dipolar ESR measurements of distances up to 8.7 nm, it is shown that all three PD-linked alphaS mutants retain the ability to transition from the broken helix to the extended helix conformation, and that the ratio of protein to detergent, rather than just the absolute detergent concentration, determines whether the protein adopts the broken or extended helIX conformation.

Electron‐spin relaxation and ordering in smectic and supercooled nematic liquid crystals
TL;DR: In this article, a deuterated liquid-crystal-like spin probe was used for line shape analysis of a benzilidene derivative (40,6) and in cyanobiphenyl derivative (S2 and 5CB) liquid crystals.

TL;DR: Analysis of the electron spin resonance spectra recorded over a range of temperatures shows that the spin-labeled phospholipids incorporated experience two types of environments, L(o) and L(d), with distinct order parameters and rotational diffusion coefficients but with some differences among the four cell lines.
