Direct-write Patterning of Bacterial Cells by Dip-pen Nanolithography |
| 초록 |
The ability of dip-pen nanolithography (DPN) to generate nano- or micro-arrays of soft or hard materials (e.g., molecular inks, DNA, proteins, nanoparticles, sols, and polymers) with a direct-write manner has been widely demonstrated. This technique, however, remains a challenge in transporting large sized ink materials such as bacteria. 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 report a straightforward “stamp-on” DPN method that uses a nano-network poly(2-methyl-2-oxazoline) hydrogel coated tip and carrier agents to generate patterns of micrometer sized Escherichia coli JM 109 bacterial cells. We demonstrate that this approach enables one to deposit a single bacterial cell array on a solid surface or layer multiple cells array by varying the viscosity of the “ink” solution. |
