Abstract:
Striped patterns have broad applications in recognition, cell culture, and droplet manipulation. However, a rapid and robust assembly method for various striped patterns and their application demonstrations are still lacking. Here, we develop a robust and universal confined-area assembly method to position various building blocks into striped patterns using an accelerated evaporation strategy and demonstrate the applications of assembled patterns in molecular pattern and cell culture. The lowered pressure or heat is used to accelerate solvent evaporation, promoting fast convection flow in liquid and inducing stick-slip motion of triple-phase contact line. Microgel, nanoparticles, high-density microparticles, bacteria, and solutes can form striped patterns using the proposed method, showing its robust for fabricating various patterns. The wettability, encapsulating property and cell guidance ability of striped patterns are investigated, exhibiting their potential applications in different fields. The proposed accelerated evaporation-induced confined-area assembly is a rapid and effective approach for preparing striped patterns from different components for advanced functions.
