"Micro- and Nano-scale manufacturing – the converge of Science and Technology"

Abstract:

While exciting research discoveries at micro- and nano-scale science and technology stream continually from research laboratories, due to the lack of new manufacturing paradigms, scaling to industrial level production still faces critical challenges. The wide dimensional scale and high complexity of nano-engineered systems and products requires truly 3D micro and nano-manufacturing techniques which are not available presently.

In this talk, I’ll first discuss a unique 3D micro-manufacturing technology – Microstereolithography that has been developed for engineering complex microstructures for the applications in integrated photonics as well as scaffold tissue engineering. In the following part, I’ll discuss the development of a new nano-manufacturing paradigm based on a unique physical concept of optical superlensing, which breaks down so called diffraction limit. The device application in Bio-sensing will also be discussed.

Biography:

Professor Cheng Sun is Assistant Professor at Mechanical Engineering Department at Northwestern University since September 2007. He received his PhD in Industrial Engineering from Pennsylvania State University in 2002. He received his MS and BS in Physics from Nanjing University in 1993 and 1996, respectively.  Prior to coming to Northwestern, he was Chief Operating Officer and Senior Scientist at the NSF Nanoscale Science and Engineering Center for Scalable and Integrated Nanomanufacturing at UC Berkeley.

Sun’s primary research interests are in the fields of Emerging applications of nano-electronics, nano-photonics, nano-electromechanical systems and nano-biomedical systems necessitate developments of viable nano-manufacturing technologies. His research group is engaged in developing novel nano-scale fabrication techniques and integrated nano-system for bio-sensing and high-efficiency energy conversion. He has published more than 50 technical papers including publications in Science, Nature Photonics, and Nature Materials.
