与高通量电位A微型用于演示的三维（3D）介电电泳（DEP）的新颖材料。石墨烯纳米薄片纸，双面胶带交替堆叠;一个700微米的微井钻横切层。的聚苯乙烯小珠的DEP行为表现在微井。

该协议演示了制造 3D 层压石墨烯纸、电极微器件的程序，以及通过在设备内通过 DI 电泳或 DEP纵聚星珠或生物细胞的实验方法。从这一点开始，我们将介电泳称为 DEP。通过首先交替堆叠 50 微米的绘图纸和 N 减去 100 微米的压敏聚合物胶带层来完成器件的制造，产生一半信号和一半接地电极。

将各层压在一起，修整，然后在结构中钻出微型井。最后，使用银环氧树脂将两条铜引线连接到器件的两端。第二步是制备具有所需电导率的 DEP 填料。
