Abstract
It is found that the NMR relaxation rates of diffusants in peptide hydrogels have a linear dependency on the shear modulus of the hydrogels. This finding opens the door for non-invasive and forceless mechanical characterizations of materials and tissues using NMR and MRI.
摘要
研究发现，肽水凝胶中扩散剂的核磁共振弛豫率与水凝胶的剪切模量呈线性相关。这一发现为利用核磁共振和磁共振成像对材料和组织进行非侵入性和无外力的力学表征打开了大门。
