Title: Programmable Patterning of Polymeric Microparticles By Floating Electrodes-Assisted Electrospray
Creators: Zhang, Xu
Advisor: Zhao, Yi
Issue Date: 2012-02
Abstract: We introduce an innovative method for patterning one or multiple types of polymeric microparticles by electrospraying them towards 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. Co-patterning of multiple types of particles on a planar surface and along the vertical direction is demonstrated. With the superior co-patterning capacity and the simple configuration, this work is expected to facilitate the development of biosensing, microscale tissue engineering and other microparticle-based total analysis.
