Pathogen detection has a huge importance in the food industry and it can play significant role in the medical practice. This paper focus on the fabrication methods of diamond coated Love wave surface acoustic wave (LW-SAW) biosensors for bacteria detection. LW-SAW sensors have been fabricated on AT-quartz crystals. Interdigitated transducers have been patterned by RF sputtering and photolithography techniques. Amorphous silicon oxide (SiO2) guiding layer and nano-crystalline diamond layer were both deposited by plasma enhanced chemical vapor deposition at low temperature. Preliminary experimental study of diamond surface termination for sensors bio-functionalization is also reported.
