摘要
Scalablenanolithography: Through precisely tuning the nanometer scale deformation ofthe soft stamps and in combination with the latest chemical lift-offlithography developed in our group, we developed polymer pen chemical lift-offlithography and self-collapse lithography. Based on which, sub-20 nm resolutionsurface chemical patterning can be realized at high throughput. Multiple-patterning nanosphere lithographywas developed to scalable fabricate fully tunable three-dimensionalnanostructures at a resolution of 50 nm. Micromotors: Using the “electrictweezers”, micromotors with precisely controlled mechanical motions includingmovement, rotation, and assembling were developed. Multi-functional nanomotorswere further developed as a prototype of future biomedical nanorobots, whichcan actively assemble into ordered arrays, do single-molecule level sensing anddelivery to designated single cells for bioanalysis, and tunable releasemolecules at designated location.
