摘要

本研究探讨了胶原蛋白的加入如何影响琼脂糖水凝胶的流变学和运输特性。胶原蛋白不影响水凝胶的流变特性(即振幅和频率响应曲线的整体形状),但会根据两种成分的浓度改变其粘弹性模量和网孔大小。测定了带相反电荷的模型染料伊红B和亚甲基蓝在所有水凝胶中的扩散系数,并证明了静电相互作用的深刻影响。与添加丝素的类似工作的比较表明,虽然这些蛋白质对多糖网络的粘弹性性能的影响可能是相似的,但它们对网络传输性能的影响可能不同。

Impact of Collagen on the Rheological and Transport Properties of Agarose Hydrogels.

This work investigated how collagen addition affects the rheological and transport properties of agarose hydrogels. Collagen did not affect the rheological character of hydrogels (i.e., the overall shape of amplitude and frequency response curves) but changed their viscoelastic moduli and mesh size dependent on the concentration of both constituents. The diffusion coefficients of the oppositely charged model dyes eosin B and methylene blue were determined in all hydrogels and demonstrated a profound effect of electrostatic interactions. Comparison with similar work with fibroin addition showed that while the effects of these proteins on the viscoelastic properties of a polysaccharide network can be similar, their impact on network transport properties may be different.

期刊介绍: The journal Gels (ISSN 2310-2861) is an international, open access journal on physical (supramolecular) and chemical gel-based materials. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the maximum length of the papers, and full experimental details must be provided so that the results can be reproduced. Short communications, full research papers and review papers are accepted formats for the preparation of the manuscripts. Gels aims to serve as a reference journal with a focus on gel materials for researchers working in both academia and industry. Therefore, papers demonstrating practical applications of these materials are particularly welcome. Occasionally, invited contributions (i.e., original research and review articles) on emerging issues and high-tech applications of gels are published as special issues.
