P2.3.14 Optical Waveguide Sensor Based on Transparent Nanocrystalline Diamond Film

Kyeong-Seok Lee, Wook-Seong Lee & Hak-Joo Lee
Besides the excellent biocompatibility, covalent bonding with biomolecules, mechanical and chemical durability, recent progress in the growth of nanocrystalline diamond film with a smooth surface and a good transparency has motivated its use in optic-based biosensing. In this paper, we present and demonstrate the first visible-range optical waveguide sensor based on nanocrystalline diamond film. Hot-filament CVD method was used to synthesize the diamond film and the deposition conditions were carefully controlled. Attenuated total reflection type...
