NOVELTY - A novel surface plasma laser element resonance biologic sensor , of prism (1), nanometer particle array (2), a silicon dioxide thin film (3), graphite (4) and sample pool (5) is composed of the nano granule array (2) is located in the prism (1) and the following surface, silicon dioxide thin film (3) cover in nanometer particle array (2) on, graphene (4) cover on silicon dioxide thin film (3) of, wherein the prism (1) is high refractive rate material, nanometer particle array (2) of polystyrene nano ball (6) metal thin film (7) is one. This new utility model not only use of nano granule array excitation sensitive characteristic is SPP, then use of geometrical structure of graphene oneself reinforcing feature of adsorption to the molecule to be detected, at the same time too can have protective metal is not the oxidation effect, realization of increase of the target biosensor sensitivity and accuracy.
