Abstract

Carrageenan (CGN) is a high molecular weight polysaccharide that is extracted from red seaweeds. It is made up of D-galactose residues connected by β-1,4 and α-1,3 galactose-galactose bonds. As a result of its ability to thicken, emulsify, and stabilize food, it is frequently used as a food additive in processed food. Its consumption has surged in recent years due to the Western diet's (WD) spread. Carrageenan has the ability to change the thickness of the mucus barrier, the composition of the gut microbiota, and the innate immune pathway that causes inflammation. Also, its inherent qualities, which include biodegradability, biocompatibility, resemblance to native glycosaminoglycans, antioxidants, anticancer, immunomodulatory, and anticoagulant activities, Carrageenan-based hydrogels have been the subject of numerous investigations lately for biomedical applications. The brittle hydrogel and uncontrollably exchanged ions, however, are two drawbacks to the application of this polysaccharide, but these can be avoided by making straightforward chemical changes to polymer networks, which create chemically bonded hydrogels with important mechanical characteristics and regulated degradation rates. Furthermore, the addition of diverse kinds of nanoparticles, as well as polymer networks, to carrageenan hydrogels results in hybrid platforms with noteworthy mechanical, chemical, and biological characteristics, which qualify them as appropriate biomaterials for tissue engineering (TE), drug delivery (DD), and also wound healing applications. Our goal in this article is to provide an overview of the most current developments in hybrid carrageenan-based platforms and several chemical modification techniques for TE and DD applications.

卡拉胶基水凝胶用于组织工程中的高级伤口愈合和控制药物输送
Carrageenan (CGN)是从红海藻中提取的高分子量多糖。它由d -半乳糖残基由β-1,4和α-1,3半乳糖-半乳糖键连接而成。由于其增稠、乳化和稳定食品的能力,它经常被用作加工食品中的食品添加剂。近年来,由于西方饮食(WD)的普及,其消费量激增。卡拉胶能够改变黏液屏障的厚度,肠道菌群的组成,以及引起炎症的先天免疫途径。此外,卡拉胶基水凝胶的固有特性,包括生物可降解性、生物相容性、与天然糖胺聚糖的相似性、抗氧化剂、抗癌、免疫调节和抗凝血活性,最近已成为许多生物医学应用研究的主题。然而,易碎的水凝胶和不受控制的交换离子是这种多糖应用的两个缺点,但这可以通过对聚合物网络进行直接的化学改变来避免,这种改变可以产生具有重要机械特性和可调节降解率的化学键合水凝胶。此外,在卡拉胶水凝胶中加入不同种类的纳米颗粒和聚合物网络,形成了具有显著机械、化学和生物学特性的混合平台,使其成为组织工程(TE)、药物输送(DD)和伤口愈合应用的合适生物材料。我们在这篇文章中的目标是提供最新发展的杂化卡拉胶为基础的平台和几种化学改性技术的TE和DD应用的概述。

期刊介绍: Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats: • original research reports • short research and development reports • scientific reviews • current concepts articles • special reports • editorials Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
