  Dr. Ni received his Ph.D of Physics in 2012 from Utrecht University (the Netherlands) working with Prof. Marjolein Dijkstra focusing on the computational study on the self-assembly of colloidal systems. From 2012 to 2014, he did his postdoc with Profs. Martien A. Cohen Stuart and Peter G. Bolhuis focusing on the self-assembly of fibril-forming polypeptides. In 2014, he was awarded the NWO VENI fellowship which is the most prestigious personal grant for young scientists in the Netherlands to start independent research lines.In March 2016, he joined the School of Chemical and Biomedical Engineering in Nanyang Technological University as an assistant professor. In 2016, he was awarded the Best Research Prize by the European Cooperation in Science and Technology (COST) Action – Flowing Matter [An annual prize for European Early Stage Researchers in soft matter within eight years after the date of PhD]. His research has been published in a number of top scientific journals, e.g. Nature, Nature Communications , Science Advances, PNAS, PRL, ACS Nano, Soft Matter, etc.
Abstract: The ultimate goal of self-assembly is to find a way to direct each of the building blocks to occupy its specific location to spontaneously form a designed structure. Recent development of DNA origami to some extent offers a solution for this, but similar idea can not be applied directly to assemble particle based colloidal superstructures. In this talk, I will present our recent work in the self-assembly of linker mediated mobile DNA coated colloids, which we find can address two major experimental challenges in present programmable assembly of DNA coated colloids, and offers a new way to realise so-called 'colloidal origami'.
