Dip-Pen Nanolithography (DPN) is a scanning probe nanopatterning technique, in which an AFM tip is used to deliver materials to a surface through a water meniscus formed between the tip and the surface. This direct-write DPN technique offers high-resolution patterning capabilities for a number of ‘inks’ materials such as small organic molecules, biomolecules, metal nanoparticles, and conducting polymers on the solid surface. In this work, we have patterned graphene oxide(GO) on amine-functionalized silicon oxide substrate via DPN technique with poly(2-methyl-2-oxazoline)-coated and hydrophilically treated AFM tip. The results showed that micrometer sized GO patterns were successfuly generated on the solid surface. The DPN patterns of GO and reduced GO(RGO) were chracterised by EDX, SEM and micro-Raman spectroscopy. |
