Welcome to Prof. Cheng Sun's research group at Northwestern University. Our group aims to develop innovative technologies in pushing the capabilities into a whole new dimension, including super-resolution nano-imaging, high-throughput nano-fabrication/nano-manufacturing, high sensitivity biosensing, as well as high efficiency energy conversion. We are currently exploring a variety of projects in our group, including optical Metamatierals, Plasmonic nano-photonics, novel 3D micro/nano-fabrications, and nano-bio interface.
