The Department of Physics is pleased to welcome Dr. Chrisy Xiyu Du for a virtual colloquia presentation. Dr. Chrisy Xiyu Du is a Postdoctoral Researcher in the Brenner Group at the Harvard School of Engineering and Applied Sciences, specializing in programmable assembly of bio-inspired materials using statistical mechanics framework and molecular dynamics simulations.


Biological materials gain complexity from the programmable nature of their components. To manufacture materials with comparable complexity synthetically, we need to create building blocks with low crosstalk so that they only bind to their desired partners. Canonically, these building blocks are made using DNA strands or proteins to achieve specificity. Here we propose a new materials platform, termed Magnetic Handshake Materials, in which we program interactions through designing magnetic dipole patterns. This is a completely synthetic platform, enabled by magnetic printing technology, which is easier to both model theoretically and control experimentally. In this seminar, I will give an overview of the development of the Magnetic Handshake Materials platform. I will start with discussing the theoretical foundations of how we model and design specific interactions using an information theory based framework. I will then talk about how we utilize the anisotropic nature of magnetic dipoles to design energy landscapes, leading to materials assembly and properties design. Lastly, I will briefly touch on the experimental advancement of the system, showcasing potential future applications.
