Dip-pen nanolithography (DPN) is a powerful method to pattern nanostructures on surfaces. Using DPN, nanostructure patterns of extraordinary complexity can be created. This technique has potential applications for gene chips and multiple biomolecular arrays because one can create patterns with numerous molecules in direct-write fashion. This technique, however, remains a challenge in transporting large sized ink materials such as bacteria, carbon nanotubes(CNT), because the size limitation of water meniscus formed between the tip and the solid surface becomes a bottleneck in such diffusion-based molecular transport experiments. In this work, we have patterned CNT on amine-functionalized silicon oxide substrate via DPN technique with poly(2-methyl-2-oxazoline) hydrogel coated AFM tip and carrier agents. The results were characterised by AFM, SEM. |
