In this letter, using direct-write dip-pen nanolithography to generate nanoscale patterns of poly-L-lysine on mica was described. Poly-L-lysine molecules can anchor themselves to the mica surface through electrostatic interaction force, so stable poly-L-lysine patterns, such as square, line, circle and cross, could be obtained on freshly cleaved mica surface. From AFM image of the patterned poly-L-lysine nanostructures on mica, we know that poly-L-lysine was flatly bound to the mica surface. These oriented patterns of poly-L-lysine on mica can provide the prospect of building functional nanodevices and offer new options for this technique in a variety of other significant biomolecules.展开更多

Using Bovine Serum Albumin(BSA) as the ink in the DPN procedure, we were able to utilize lateral force microscopy(LFM) images to differentiate between Au substrate and patterned area with deposited monolayers of BSA. Then the first evidence for Au_S bonding was reported between the gold substrate and the BSA surface thiol groups given by the angle resolved XPS measurements.展开更多

The process of dip-pen lithography involves the adsorption of ink molecules on AFM tip, the formation of water meniscus, the transport of ink molecules, and diffusion of ink molecules on the substrate. More factors such as temperature, humidity, tip, scanning speed and so on will influence the process of dip-pen lithography. The paper analyzes in detail the mechanism of this technique, introduces synthetically the latest development, including electrochemical DPN, more-mode DPN, multiple DPN, multi-probe array DPN and so on. Finally, the paper describes the characteristics and the application of DPN.展开更多

Although DPN is a powerful tech-nique, it has not shown its ability of direct-writing and pat-terning of nanostructures on surfaces of soft materials, for example biomacromolecules. Direct depositing on soft sur-faces becomes possible with the introduction of a com-bined-dynamic mode DPN rather than mostly used contact mode DPN or tapping mode DPN. In this report, the com-bined dynamic mode DPN is used for direct depositing pro-tein ink on DNA molecules at the nanometer scale.展开更多
