Linear dependence of the water proton transverse relaxation rate on the shear modulus of hydrogels

摘要

It is found that hydrogelation of peptides enhances the transverse relaxation rate R_2 of water protons but has no effect on the longitudinal relaxation rate R_1 and the diffusion coefficient D. The magnitude of water proton R_2 enhancement increases linearly with the shear modulus G of hydrogels.
