Content abstract: Hydrogel is one of the best biomimetic extracellular matrix (ECM). ECM is a network structure supporting and connecting tissues. It mainly regulates the occurrence of tissues and the physiological activities of cells. The chiral characteristics of ECM play a decisive role. However, the research on chiral regulation of tissue cells by ECM is still in the exploratory stage, and the nature and mechanism of its influence on cell adhesion and growth are still in the exploratory stage. Old is a key scientific problem that needs to be solved urgently. To carry out relevant research can not only understand the origin of stereoselectivity in the life system, but also have application value in biomedical health and other fields. The key to solve this problem is how to design molecular structure to construct chiral biomimetic hydrogels and study their interaction with cells and biomolecules. In order to solve the above scientific problems, our research group has introduced the idea of functionalization into the design of Supramolecular Gel molecular structure in the past few years. We synthesized a series of chiral supramolecular gel factors based on C2 symmetry, which had the characteristics of module design, and constructed a series of chiral controllable, functional adjustable, intelligent response biomimetic nanofibers self-assembly. The highest content of water was up to 99. 94%, with 10-80 micron porous structure, nanofibers in diameter between 10-300 nanometers, meet the needs of cell growth space. Focusing on the basic and applied research of chiral hydrogel materials, the design idea of chiral center gel is proposed, and the principles and methods of long-range chiral hydrogel are discovered. The chiral regulatory properties of hydrogels are given, revealing the selective rule of interaction between cells and chiral nanostructures, and developing the importance of chiral structure in tissue engineering. Based on the theory, the characteristics of multiple functions of chiral hydrogels were explored, and the application and development of extracellular culture matrix based on chiral hydrogels were guided, which provided new ideas and methods for tissue engineering research based on chiral biomimetic microenvironment.
