Abstract

To explore the most dynamic cross field of nanotechnology and life science, and to find a more practical method of fabricating nanodevices on a very large scale with advantages of low manufacturing cost, high reliability and reproducibility, we successfully fabricated a submicron IrO2 nanowire array biosensor platform by conventional complementary metal-oxide- semiconductor (CMOS) process. Single crystal IrO2 nanowire array was grown uniformly on a 6-in. wafer surface by chemical vapor deposition (CVD) method and patterned into submicron array clusters. The obtained clusters were positioned in a designed pattern similar to a multiple electrode array (MEA) format, and each was individually addressed. The fabrication method was found to be reliable, low cost and robust. The final chip showed excellent transparency, functionality and durability.
