This present study intends to fabricate a specific template of multi-layered micro/nano-particles and/or metal thin-films, to investigate adhesion properties of nano-materials such as carbon nanotubes and protein molecules for some conditions (surface wettability, temperature, geometry), and to demonstrations of micro-patterned nano-materials for their patterning based on transfer-print process. It is found that carbon nanotubes (CNT) and specific protein molecules could be attached on the side-walls of micro-structured surface of micro/nano-particles as a template, because they are preferable to adsorb on micro/nano-scale roughness on the side wall of layered structures. Some nano-materials also could be transferred to another substrate to allow their geometry to be maintained. The adhesion characteristic and transferring accuracy are strongly affected by surface wettability.
