Lecture Introduction

With the rapid development of nanotechnology, the biomedical field is paying more and more attention to how to use nanomaterials and nanotechnology to solve problems in clinical diagnosis and treatment. Based on the research progress of the research group in recent years, this report systematically introduces the core and related strategies of superstructure assembly strategies, how to construct nanostructures with specific functions on demand, how to accurately and controllably assemble these "building blocks" into macroscale functional structures, develop new assembly strategies, and break through the preparation bottleneck of "nano primitives-macromaterials". Similarly, hydrogels have become a research hotspot in the field of wound repair due to their excellent biocompatibility, controllable drug release capabilities and biomimetic extracellular matrix properties. They are a key frontier for realizing the practical application of nanotechnology. However, there is insufficient regulation of drug release kinetics, a single antibacterial mechanism can easily induce the evolution of drug resistance, and there is a lack of key technologies to actively intervene in the wound repair microenvironment. Combining the common advantages of inorganic nanomaterials and hydrogel materials to form composite functional hydrogel materials can achieve certain clinical purposes, promote the effective combination of micro (nanotechnology) and macro (tissue engineering), and promote new technology innovation.


Lecture Topic 2: Research on the Mechanism of Self-Assembled Polypeptide Fibrosis and Its Application in Neovascular-related Diseases


Introduction to the speaker

expand , Ph.D., Distinguished Associate Professor and Master Supervisor at the School of Biomedical Engineering, Chongqing Medical University. Mainly engaged in the assembly and fibrosis of polypeptides, and the application research of assembled polypeptides for disease diagnosis and treatment. He has hosted 1 National Natural Science Foundation of China project and published 10 academic papers as an author or co-author in journals such as Science Advances, ACS Nano, Biomaterials, Small, etc.


Lecture Introduction

Natural extracellular matrix proteins fibrate in response to stimuli and achieve functions such as supporting and fixing cells. Inspired by the fibrosis of natural proteins, we designed multiple peptide sequences, studied their receptor-mediated fibrosis mechanisms, and explored the application of peptides in anti-corneal neovascularization and tumor embolization therapy.
