我们介绍了一种新的方法，用于图案化一种或多种类型的聚合物微粒，通过电喷雾它们朝向与微电极阵列图案化的收集表面。通过独立地编程每个微电极的电状态，微粒可以被限制在具有高图案化对比度的期望区域内。讨论了浮置电极的构图原理和作用。演示了多种类型的颗粒在平面上和沿着垂直方向的共图案化。该系统具有上级共图案化能力强、结构简单等优点，有望为生物传感、微尺度组织工程等基于微粒的全分析提供有力的支持。
We introduce a new method for patterning one or multiple types of polymeric microparticles by electrospraying them toward a collecting surface patterned with an array of microelectrodes. By independently programming the electric state of each microelectrode, microparticles can be confined within desired regions with a high patterning contrast. The patterning principle and the role of the floating electrodes are discussed. Copatterning of multiple types of particles on a planar surface and along the vertical direction is demonstrated. With the superior copatterning capacity and the simple configuration, this work is expected to facilitate the development of biosensing, microscale tissue engineering and other microparticle-based total analysis.
