In recent years, interface shearing technology has garnered substantial attention as an emerging methodology for fabricating advanced micro-nano topological materials. The mechanism underlying this technology is straightforward, and the apparatus is both simple and feasible. The resultant advanced micro-nano topological materials exhibit distinctive characteristics and offer a high degree of controllability. This review endeavors to furnish a thorough examination of the developmental history of interface shearing technology, providing an in-depth exploration of its technical mechanism. The shearing of the vertical-axis interface encompasses various techniques, including single-axis, coaxial, parallel-axis, and composite-axis shearing. On the other hand, oblique-interface shearing involves the one-step preparation of micro-nano materials and induces inertial sorting effects. A comparative analysis was conducted among different interface shearing techniques, summarizing advanced micro-nano topological materials with varying dimensions based on these techniques. The techniques discussed encompass microdroplets (zero-dimensional), microfibers (one-dimensional), and microdroplet arrays (two-dimensional). The text delineates exemplary applications of micro-nano materials, encompassing cell encapsulation and adhesion, proficient water collection, and gradient-responsive microcapsules, among others. The conclusion encapsulates a summary of the present research advancements, emphasizing challenges within interface shearing technology and prospective future hurdles. This review is dedicated to furnishing researchers with pertinent insights into interface shearing technology and innovative concepts for the preparation of advanced micro-nano topological materials.
