生物软组织和合成水凝胶都属于同一类“软而湿”的物质，即它们都是软的并且含有水。然而，尽管生物组织如肌肉显示出各种形式的功能性，但水凝胶通常具有差的功能性，这主要是由于结构上的差异-生物组织具有复杂的结构，而大多数水凝胶是无定形的。近年来，生物大分子、嵌段共聚物和液晶分子已被用于通过分子间的非共价相互作用（如离子键、疏水相互作用和氢键）在合成的物理或化学水凝胶中发展自组装结构。不同长度尺度上的有序结构赋予水凝胶额外的功能，在材料科学中具有广阔的应用前景，例如在组织工程和机械光学传感器中。本文简要介绍了近年来分子组装有序结构水凝胶的设计方法及其功能。
Biological soft tissue and synthesized hydrogel both belong to the same ‘soft and wet’class of substances, that is, they are both soft and contain water. However, whereas biological tissue such as muscles displays various forms of functionality, hydrogels generally have poor functionality, primarily due to the difference in structure—biological tissue has a sophisticated structure whereas most hydrogels are amorphous. In recent years, biomacromolecules, block copolymers and liquid-crystalline molecules have been used to develop self-assembled architectures in synthetic physical or chemical hydrogels via intermolecular noncovalent interactions such as ionic bonding, hydrophobic interactions and hydrogen bonding. Ordered structures on various length scales endow the hydrogels with additional functions with promising applications in materials science, such as in tissue engineering and mechano-optical sensors. In this review, we briefly describe the recent developments in designing hydrogels with ordered structures of molecular assemblies and the resultant functionalities.
