As a target in biochip development, technological expansion is expected in the fields of microbiological and medical diagnostics, food science, environmental science and health care. Since the electrochemical detection method is suitable for the miniaturization and cost reduction of detection devices and exhibits high digitization sensitivity and rapidity, detection systems of composed of biochips are expected to be come more increasingly important in the future.
Lab-on-a-chip, called the ultimate biochip, is the device that the reactions and changes of the protein detects and analyzes instantly.
A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material exhibiting elasticity, with an amplitude that typically decreases exponentially with depth into the substrate.
The purpose of this study is to produce a liquid phase system sensor using a longitudinal wave radiation into a liquid phase by Rayleigh wave, which is one of the SAW mode.
Rayleigh type SAW sensor using a grooved holder is supposed to be used on a lab-on-a-chip, we report on the research results from the measurements of the protein concentration as an antibody and Adenosine of the energy metabolites of biological and so on.
