Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

open access: yesAdvanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Alkylating spin labels for spin-labelling of DNA

International Journal of Biochemistry, 1983
Abstract 1. 1. Five alkylating spin labels, termed SL1, SL2, SL3, SL4 and SL5, have been synthesized and their suitability for spin-labelling of DNA was studied. 2. 2. It was found that one of them (SL5) lost its free radical moiety under the conditions of spin-labelling, thus giving DNA with no EPR signal. 3. 3.

Spin labeling EPR

Photosynthesis Research, 2009
Site-directed spin labeling in combination with electron paramagnetic resonance spectroscopy has emerged as an efficient tool to elucidate the structure and conformational dynamics of biomolecules under native-like conditions. This article summarizes the basics as well as recent progress of site-directed spin labeling.

The binding of spin-labeled propranolol and spin-labeled progesterone by orosomucoid

Biophysical Chemistry, 1982
The binding of the spin-labeled propranolol and spin-labeled progesterone to human orosomucoid has been studied as a function of temperature by electron spin resonance (ESR) techniques. At 20 degrees C the association constants are 1.9 x 10(6) and 4.9 x 10(5) M-1, respectively. In each case, the binding is competitive with unlabeled ligand. Above about
