Abstract: Microcontact printing(μCP) technology has been shown to be an easy,inexpensive and low-cost approach for microfabrication. We inked the poly(dimethylsiloxane) elastomeric stamp by rubbing the stamp gently with 10 mmol•L-1 octadeyl trichlorosilane(OTS) in hexane solution, then applied the dried stamp to cover glasses and the outer surface of tubes. We also micropatterned a glass rod surface by scrolling the rod on the patterned surface of an inked stamp. Patterned substrates were immersed in the silver plating bath for 30 min to selective deposition of silver on OTS free part of the substrates to obtain 2D and quasi-3D microstructure of silver. The microscope images show that microcontact printing technology can fabricate 2D and quasi-3D microstructure rapidly and easily, with high fidelity, which further demonstrates potential application of μCP in microfabrication technology.
