Hydrogels are a kind of three dimensional polymeric network system which has a significant amount of water imbibing capacity despite being soluble in it. Because of the potential applications of hydrogels in different fields such as biomedical, pharmaceutical, personal care products, biosensors, and cosmetics, it has become a very popular area of research in recent decades. Hydrogels, prepared from synthetic polymers and petrochemicals are not ecofriendly. For preparing biodegradable hydrogels, most available plant polysaccharides like starch are utilized. In its structure, starch has a large number of hydroxyl groups that aid in hydrogel networking. For their easy availability and applications, starch-based hydrogels (SHs) have gained huge attention. Moreover, SHs are non-toxic, biocompatible, and cheap. For these reasons, SHs can be an alternative to synthetic hydrogels. The main focus of this review is to provide a comprehensive summary of the structure and characteristics of starch, preparation, and characterization of SHs. This review also addresses several potential multidimensional applications of SHs and shows some future aspects in accordance.

基于淀粉的可持续水凝胶概述：潜在应用和方面

水凝胶是一种三维聚合物网络体系，尽管可溶于其中，但具有显着的吸水能力。由于水凝胶在生物医学、制药、个人护理产品、生物传感器和化妆品等不同领域的潜在应用，它已成为近几十年来非常受欢迎的研究领域。由合成聚合物和石化产品制成的水凝胶并不环保。为了制备可生物降解的水凝胶，使用了大多数可用的植物多糖，如淀粉。在其结构中，淀粉具有大量有助于水凝胶网络化的羟基。由于其易于获得和应用，淀粉基水凝胶（SHs）受到了极大的关注。此外，SH 无毒、生物相容性好且价格低廉。由于这些原因，SHs 可以替代合成水凝胶。本综述的主要重点是对淀粉的结构和特性、SHs 的制备和表征进行全面总结。这篇综述还讨论了 SH 的几个潜在的多维应用，并显示了一些未来的方面。
