Method for detecting target object by utilizing color-developable imprinting colloid film

The invention relates to a method for detecting a target object by utilizing a color-developable imprinting colloid film. A solution to be detected containing an objected to be detected is coated on the color-developable imprinting colloid film through a container with balls, and thus whether the target objected is contained in the objected to be detected is judged by observing whether the color-developable imprinting colloid film changes color. According to the method for detecting the target object disclosed by the invention, the restriction for laboratory environment can be thoroughly eliminated, expensive time, material resource and manpower costs are reduced, the randomness for detectors and sites is realized, qualitative/quantitative determination of naked eyes with high specificity and sensitivity is obtained, and the result is detected in real time.
