Abstract: We use 8 nm magnetite nanoparticles as "ink", self assembly monolayer(SAM) of bovine serum albumin(BSA) as "paper" to generate arbitrary structures at micro or nanometer scales in the DPNprocedure. AFMand LFMare used to image the patterns. The height profile of pattern is about 8 nm, which is consistent with the diameter of magnetite nanoparticles. It means that the magnetic monolayer pattern has been obtained. The SAM of BSA is measured by diffuse reflection IRspectra and the data is coincided with the one of the literature. After writing the magnetite "ink", the band of magnetite appears at 570 cm-1 , which gives a further proof.
