基于“纳米蘸笔技术”的单个纳米颗粒在不同基底表面的转移
Transfer of single nanoparticle between different surfaces based on single-particle dip-pen nanolithography
【摘要】 本文介绍了一种可定位拾取并重新放置单个纳米颗粒的方法。这种技术被命名为"单颗粒纳米蘸笔技术"。它采用原子力显微镜针尖作"笔",俘获基底表面的单个纳米金颗粒,并将之精确定位地转移到其它基底表面。
【Abstract】 Single gold nanoparticles deposited on the solid substrates have been captured and re-deposited by using a novel technique termed as single particle dip-pen nanolithography(SP-DPN).The SP-DPN employs an atomic force microscope(AFM)tip as a "pen",which is inked with gold nanoparticles in a one-by-one fashion.Nanoparticles adhered to the AFM tips can be controllably released and re-deposited on another surface.This method is opening opportunities for direct applications in single-electron electronics and nanofabrication of nanoelectromechanical system.
