| 초록 | Dip-Pen Nanolithography (DPN) technique is an attractive nanofabrication tool for the researchers working in the areas of nano-material science, electronic devices, chip-based biosensors and proteomics, because it allows one to pattern organic/inorganic small molecules, polymers, and biomolecules such as DNA, proteins, viruses onto a variety of surfaces. However, in spite of their advantages, the DPN system has three major problems to improve for the wide use in the biochip industry. :(1) low diffusion rate of a high-molecular weight molecules through water meniscus. (2) limited ink volume on the tip surface. (3) retaining of biological activity on the tip surface. Herein, we present the strategy that solve those problems by the modification of silicon tip surface with hydrophilic nanoporous polymers. Polyoxazoline polymer was coated on the tip surface by ring opening polymerization, and the size of nanopore was controlled by the reaction conditions. The properties of a bulk polymer and the nano-porous tip were characterized by FT-IR, H-NMR, DSC, SEM, and AFM. 1. Lim. J.-H, Ginger. D. S, Lee. K.-B, Heo. J, Nam. J.-M, C. A. Mirkin, Angew.
