Assembling functional materials into one‐dimensional arrays is an efficient method for the integration of devices. However, the complicated assembly methods and poor stability of patterns still restrict their further applications. In this work, the well‐dispersible nanosheets are prepared by introducing a bionic adhesive strategy. The oriented arrays with uniform morphology and precise position are realized by the liquid‐film‐induced capillary bridge assembly method. Owing to the abundant interactions between catechol structure and targeted substrates, the micro‐wires present extraordinary stability in adhesion tests. Field‐effect transistors (FETs) based on these micro‐wires are also fabricated, and enhanced carrier mobility is achieved, exhibiting to be 41 times higher than pristine film‐structured FETs. Micro‐wires have a certain stability and improved electrical properties at the same time, which endows this strategy with practicality and application prospect.
