题 目： Versatile biomanufacturing through cell-material feedback
报告摘要：
A key focus of synthetic biology is to utilize modular biological building blocks to assemble the cell-based circuits. Scientists have programmed the living organisms using these circuits to attain multiple delicate and well-defined functions. With the integration of tools or technologies from other disciplines, these rewired cells can achieve even more complex tasks. In this talk, we will present our recent work in versatile biomanufacturing of biologics and functional material fabrication by integrating the engineered cells and polymer physics and chemistry. By exploiting cell-material feedback, we are able to design a concise platform to achieve versatile production, analysis, and purification of diverse proteins and protein complexes, and also assembly of functional living materials. Our work demonstrates the use of the feedback between living cells and materials to engineer a modular and flexible platform with sophisticated yet well-defined programmed functions.

题 目：Synthetic Chemistry in Living System
报告摘要:
The cell is a tiny but complex reactor, which completes the life process through a series of complex chemical reactions (metabolic pathways) under mild conditions. From a chemical point of view, if we can replace flask with cell to do the chemical reaction. In this seminar, I will explore the design of fluorescent probes and drugs through in vivo chemistry and explore their applications in disease monitoring and treatment. I will mainly introduce (1) a photoactivated prodrug system based on controllable intracellular polymerization. This method successfully induces programmed cell death such as apoptosis and necrosis by in situ synthesis of high molecular polymers with controllable structures in tumor cells, and inhibits cell proliferation by interfering with the cell cycle. The most important thing is significant Inhibits the migration ability of tumor cells. (2) gamma/X-ray radiation is used to mediate the activation of two cancer prodrugs, thereby realizing precise and coordinated radiotherapy and chemotherapy..

题 目： Hydrogels with Unprecedented Mechanics for Human-Machine Interfacing
报告摘要:
The human tissues and organs are mostly soft, wet and bioactive; however, machines are commonly hard, dry and biologically inert. Bridging human-machine interfaces is of importance to address those grand challenges in health, energy and suitability. Functional soft materials emerging at the interface between electronics and biological systems are challenging our fundamental knowledges, motivating technological innovations, and enabling impactful applications. Inspired by the nature’s design principles, a great variety of functional hydrogels with unprecedented properties and functions could be readily manufactured for human-machine interfacing. In this talk, I will mainly focus on how to engineer hydrogel materials with unprecedented mechanics, such high toughness and fatigue-resistant properties, by rational control of the multi-length scale structure. Such emerging soft materials could be further engineered as the ingestible electronics for long-term monitoring important physiological conditions and biomarkers, important loading bearing components for soft robots or hydrogel armours. Moreover, fatigue-resistant adhesion between soft materials and engineering matrix, i.e. metals, ceramics, elastomers, will also be discussed.
