Abstract

The chameleon change color when the environment changes, the gecko's feet have super adhesion ability, and the surface of lotus leaf is hydrophobic. All of these are due to their micro/nano structures. So the biomimetic micro/nano structures have attracted much attention due to their broad applications in self-cleaning, microelectronic devices, information storage, plasma optics, biomedical interfaces, micro/nanofluidic and sensors. My research is about the fabrication and application of biomimetic micro/nano structures based on the colloidal lithography. The colloidal lithography is a technique for fabricating ordered micro/nano structures using 2D or 3D colloidal crystal as template or mask. This method is simple, low cost and suitable for large area preparation. Then the metal nanoparticles or metal layer were combined with the polymer micro/nano structure by adsorpotion or deposition. The composite micro/nano structures can be used as barcode nanorods, coaxial gold nanorings, biological interfaces and integrated micro/nanomotors.
