Qingyuan Lin received a B.S. in Physics from Peking University in China. His current research focus on making materials for light manipulation. The materials that he uses are gold nanoparticles, which are very tiny particles that could interact with light strongly in a controllable way. Just like we can use bricks to build a house which will be functional in many different ways, he wants to use those nanoparticles to design and build complex architectures that can achieve functional light manipulation. To do this, we need some glue to put these tiny particles together, and the glue that Qingyuan uses are the DNA molecules. By understanding the fundamental principles of how we can use DNA to glue these gold nanoparticles together to construct desired structures, and studying how we can control light using these architectures, functional devices could be constructed for sensing, imaging, light harvesting, or even invisible cloaks.
