title: Detection and analysis of spin signal in spin-labeled poly(l-lysine).
abstract: In this paper, the authors present the study of spin-labeled poly(l-lysine) biological molecules (polypeptides) using electron paramagnetic resonance, atomic force microscopy, and electron spin noise-scanning tunneling microscopy. In the presented studies, the authors were able to obtain the information about the local distribution of the spin signal emission, and they registered the spectra for the selected area with nanometer resolution. The preparation method of spin-labeled biopolymer, experimental setup, and the procedure of calibration are also described in detail.
