The invention belongs to the field of analytical chemistry and quick detection, and particularly relates to a red-green-blue tri-fluorescent emission molecularly imprinted sensor based on a post-imprinting mixing method and a preparation method and application thereof in accurately and visually detecting hemoglobin. The red-green-blue tri-fluorescent emission molecularly imprinted sensor is obtained by mixing red fluorescent bovine hemoglobin imprinted microspheres, green fluorescent bovine hemoglobin imprinted microspheres and blue fluorescent bovine hemoglobin imprinted microspheres throughthe post-imprinting mixing method. The sensor prepared by the method can detect bovine hemoglobin in a high-sensitivity, high-selectivity and self-correcting manner, and the sensor is wider and richerthan conventional dual-fluorescent emission molecularly imprinted sensors in fluorescent color changing range and can visually detect a target more accurately.
