Tarhan Hideki Kawakatsu Hiroyuki Fujita Published online 13 March 2007 to the authors 2007 Abstract Microtubules are filamentous proteins that act as a substrate for the translocation of motor proteins. As such they may be envisioned as a scaffold for the selfassembly of functional materials and devices. Physisorption self-assembly and combing are here investigated as a potential prelude to microtubule-templated self-assembly. Dense films of self-assembled microtubules were successfully produced as well as patterns of both dendritic and non-dendritic bundles of microtubules. They are presented in the present paper and the mechanism of their formation is discussed.

They play an essential role in a tremendous number of physiological processes and can self-arrange in vivo into supra-molecular structures such as mitotic spindles. MTs also provide a substrate suitable
