Biochip Production Method, Biochip, Biochip Analysis Apparatus, and Biochip Analysis Method

摘要

A biochip to be used for infrared reflection absorption spectroscopy analysis, which is obtainable by forming a metallic layer and an active layer made from a nonmetallic material and has a film thickness less than an infrared wavelength and remarkably flat surface on a solid base and immobilizing a probe on the active layer. A biochip analysis apparatus including the biochip, a liquid passing unit for supplying a sample liquid containing a test substance to the biochip, and an optical system entering infrared light to the biochip and detecting a reflected infrared light. A biochip analysis method using the apparatus. As described above, the novel biochip that is useful for infrared reflection absorption spectroscopy analysis, the biochip analysis apparatus incorporating the biochip, and the biochip analysis method are provided.
