The invention discloses a long-range surface plasma resonance sensor and a preparation method thereof. The sensor is formed by bonding a BK7 prism and a glass slide through cedar oil, wherein the outer surface of the glass slide is plated with a magnesium fluoride thin film, a silver film and a gold film in turn; the gold film is directly contacted with biological solution to be detected and is used for detecting the biological solution in a mode of angle modulation; magnesium fluoride with the refractive index of about 1.38, which is close to that of the biological solution, can form approximatively symmetric structures on two sides of a metal conductive layer so as to ensure that surface plasmas on the two sides of the metal conductive layer are coupled to form the long-range surface plasma; compared with other metals, the metal silver used as the conductive layer has a narrower half band width of a resonance absorption peak, but has unsteady chemical properties; a conductive layer gold film can make a resonance angle generate a greater transition along with the change of the refractive index of the biological solution to be detected; simultaneously, the conductive layer gold film has stable chemical properties and high biological affinity. The specific multilayer film structure can integrate the advantages of each film and effectively improve the sensitivity of biological sensors.
