摘要: Synthesis of well-defined particle with tunable size, shape, and functionalities is strongly emphasized for various applications such as chemistry, biology, material science, chemical engineering, medicine, biotechnology. This study presents micromolding method the fabrication anisotropic particles elegant control curvature covex roof. For demos- tration rapid particles, we have applied polydimethylsiloxane (PDMS) micromold structure guiding tem- plate wetting fluid to roof particles. Based on this approach, can radius from 20 µm 70 different aspect ratio mold. In addition, fluids properties also modulate height We envision that methodology promising tool precise shape in 3-dimensional space new synthetic route cost effective, simple, easy, fast procedure.
