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.
