Irradiation of a number of different sutures largely employed in the clinical practice with either high energy electrons or with g-rays followed by quenching with glycidyl methacrylate (GMA) conveniently led to derivatization through a radical-based process. The radicals involved were detected by means of ESR spectroscopy and were characterized on the basis of their ESR spectral parameters which were also found to be consistent with the hfs constants predicted by DFT calculations. Evidence of the GMA derivatization of the sutures was obtained via (13)C CP-MAS NMR spectroscopy, while its extent was evaluated gravimetrically.

Abstract
Irradiation of a number of different sutures largely employed in the clinical practice with either high energy electrons or with g-rays followed by quenching with glycidyl methacrylate (GMA) conveniently led to derivatization through a radical-based process. The radicals involved were detected by means of ESR spectroscopy and were characterized on the basis of their ESR spectral parameters which were also found to be consistent with the hfs constants predicted by DFT calculations. Evidence of the GMA derivatization of the sutures was obtained via (13)C CP-MAS NMR spectroscopy, while its extent was evaluated gravimetrically.File in questo prodotto:
