报告1： Bioinspired Adaptive Materials based on Smart Hydrogels: Sensing, Sorting, and Harvesting 报告人：Professor Ximin He Abstract：From the cellular level up to the body system level, living organisms cooperatively sensing and adapting to local environment, to transport specific biological species in the complex bio-fluids and harvesting energy from the environment to keep alive and perform various functionalities. These graceful capabilities arise from the coordination of the chemo-mechanical actions of their muscles and/or tissues with their environmentally vigilant cells, such as the molecular configuration changes and micro/macroscopic mechanical motions in response to a variety of signals. Inspired by these unique abilities, we have developed a series of dynamic material systems, which are based on stimuli-responsive hydrogel and its adaptively reconfigurable microarchitecture. This presentation will introduce several novel functionalities that this broad-based platform has demonstrated, ranging from ultrafast optical sensing of chemical and biological species, programmable and autonomous sorting of target molecules in complex biofluids or wastewater, and adaptive light tracking and harvesting. Overall, the environment-adaptive, dynamic material systems would have transformative impacts in areas ranging from medical implants that help stabilize bodily functions, to a low-coat high-throughput point-of-care diagnostic tool of diseased indicators in solution, and to smart devices that regulate energy usage.

报告2：Virus Nanoparticles as Enabling Soft-Material Building Blocks for Chemistry and Biomedical Applications
报告人： Professor Qian Wang
Abstract：Wang group is working at the interface of chemistry, biology and soft materials sciences. One of the major directions of his research is to apply protein nanoparticles, including viruses, bacteriophages and other protein assemblies, as building blocks for materials development and biomedical applications. Taking advantage of the bioconjugation chemistry and genetic modification of protein nanoparticles, they can control the self-assembly of spherical and rod-like protein nanoparticles with polymers to form 1D, 2D and 3D self-assemblies. These hierarchically assembled biomaterials offer a unique scaffold to investigate the applications in vaccine delivery, biosensing and tissue engineering. Biography：Professor Qian Wang received his B.S. and Ph.D. degrees in chemistry from Tsinghua University, Beijing, China, in 1992 and 1997, respectively. After postdoctoral research with Prof. Manfred Schlosser at University of Lausanne, Switzerland, and with Prof. M. G. Finn at the Scripps Research Institute, he started as an Assistant Professor at University of South Carolina in 2003, where he was promoted to Associate Professor (2008), Full Professor (2011), and is currently the Carolina Distinguished Professor of Chemistry. The overall research objective of Dr. Wang’s laboratory focuses on using chemical biology tools to probe intracellular activities and the development of hierarchically structured nanomaterials to study the cooperative response of cells to extracellular matrixes. Professor Wang has supervised more than 90 doctoral students and postdoctoral fellows, delivered over 140 invited talks, and published over 240 publications (H-index 53). He has received numerous awards, including NSF CAREER Award (2008), the Alfred P. Sloan Research Scholar Award (2008), the Camille Dreyfus Teacher Scholar Award (2008), the CAPA Distinguished Junior Faculty Award (2008), NSF American Competitiveness Fellow Award (2009), the Robert L. Sumwalt Professor of Chemistry (2009), the South Carolina Governor’s Young Scientist Award (2009), the USC Rising Star Award (2010), the AAAS Fellow (2012), the South Carolina Chemist Award (2016), and the University of South Carolina Russell Research Award (2017).
