    • A device (103, 106, 112, 113, 110, 152, 158, 168, 170A, 170B, 170C, 182, 184, 250, 295) acts as a particle switch to transport and/or re-direct microparticles which are in a fluid suspension. The switch (103, 107, 112, 113, 110, 152, 158, 168, 170A, 170B, 170C, 182, 184, 250, 295) comprises at least three structural branches (e.g., 103a/103b/103c, 107a/107b/107c/107d, 110a/110b/110c, 110d/110e/110f, 110g/110h/110i, 152a/152b/152c, etc.); and the branches may be connected at a common junction (103, 107, 150, 158, 258). Particles (160, 164) can be transported along the branches as a result of the forces generated along that branch. Particles are transported into or out of the particle switch via the ends (e.g., 105a, 105b, 105c, 108a, 108b, 108c) of the branches. Particles can be switched from one branch into one of the other branches. Depending on the properties of the particles, the transportation mechanism may be traveling-wave-dielectrophoresis or traveling-wave-electrophoresis.
    • 装置(103,106,112,113,110,152,158,168,170A,170B,170C,182,184,250,295)用作颗粒开关以输送和/或重新引导微粒 液体悬浮液。 开关(103,107,112,113,110,152,158,168,170A,170B,170C,182,184,250,295)包括至少三个结构分支(例如,103a / 103b / 103c,107a / 107b / 107c / 107d,110a / 110b / 110c,110d / 110e / 110f,110g / 110h / 110i,152a / 152b / 152c等) 并且分支可以连接在公共接点(103,107,150,158,258)上。 颗粒(160,164)可以沿着沿着该分支的力产生的力沿分支传送。 颗粒通过分支的端部(例如,105a,105b,105c,108a,108b,108c)被输送到或离开颗粒开关。 颗粒可以从一个分支切换到其他分支之一。 根据颗粒的性质,运输机制可以是行波介电电泳或行波电泳。
