Interface micro-rheology detection device and method

The invention relates to the technical field of interface testing, and provides an interface micro-rheology detection device and method. The interface micro-rheology detection device comprises a groove body, a glass slide, a dish body and a dish cover, the glass slide is connected with the groove body, and the glass slide and the groove body jointly form a groove; a stepped hole is formed in the bottom of the dish body; the stepped hole comprises a small hole section and a large hole section, and a connecting surface is formed at the joint of the small hole section and the large hole section; the upper surface of the slide is connected with the connecting surface; the dish cover covers the dish body. The interface micro-rheology detection device provided by the invention is provided with the groove, so that a solution with a small volume phase can be fixed, liquid-liquid or gas-liquid phases which are immiscible can coexist in a stable upper and lower layered state, the stability of an interface position in a
