A numerical model and simulation relative to an optoelectrofluidic chip has been presented in this article. Both dielectrophoretic and electroosmotic force attracting the nano-sized particles could be studied by the diffusion, convection, and migration equations. For the nano-sized particles, the protein with radius 3.6 nm is considered as the objective particle. The electroosmosis dependent upon applied frequency is calculated, which range 10² Hz from 10⁸ Hz, and provides the much stronger force to enrich proteins than dielectrophoresis (DEP). Meanwhile, the induced light pattern size significantly affecting the concentration distribution is simulated. In this end, the concentration curve has verified that the optoelectrofluidic chip can be capable of manipulating and assembling the suspended submicron particles.

本文介绍了与光电流体芯片有关的数值模型和仿真。可以通过扩散，对流和迁移方程来研究吸引纳米粒子的介电泳和电渗力。对于纳米粒子，半径为3.6 nm的蛋白质被视为目标粒子。根据所施加的频率计算电渗，其范围 从10 ^8到10 ² Hz Hz，并提供了比介电泳（DEP）强得多的力来富集蛋白质。同时，模拟了显着影响浓度分布的诱导光图案尺寸。为此，浓度曲线证实了光电芯片能够操纵和组装悬浮的亚微米颗粒。
