报告摘要:

   Polymernanostructures are very important for a wide range of fields spanning fromelectronic to biomedical researches. Conventionally, these nanostructures arefabricated via photolithography or electron beam lithography, which hassignificant limitation on the choice of polymer and the access of the equipmentby researchers. Recently, scanning probe lithography (SPL), a series oftip-based fabrication using a sharp scanning tip, has emerged as a powerful yetlow-cost tool for nanofabrication. This talk will discuss how to develop SPLfor patterning 2D and 3D polymer nanostructures. Two important strategies,including (1) the top-down direct transfer of polymer materials by dip-pennanolithography (DPN) and (2) the bottom-up grown of polymer brushes viadip-pen nanodisplacement lithography (DNL), will be discussed in detail.Finally, we will introduce some latest development of large-area fabricationusing tip-arrays, and their application in the control of cell activities suchas cell adhesion and alignment.
