报告摘要：

　　Molecular and polymeric hydrogels are useful materials for a variety of applications including the biomedical and pharmaceutical fields. Bile acids are natural compounds exist in the body of human and most animals. In their salt form or after suitable chemical modifications, they can interact with each other in a specific solvent to form gels with self-assemble fibrous network, thus the molecular gels. These nanofibers are separated at low concentrations but entangle with each other at high concentrations to form hydrogels with well-dispersed and randomly-arranged 3D fibrous networks. The results point to a marginal solubility condition needed for gelation in water. The molecular hydrogels may be potentially useful in tissue engineering, cell culture, and mechano-optical sensing.
