Figure 4

Experimental setup of (A) the nanochannel evaluation and (B) continuous particle separation for biotechnological application. The red (+) sign indicates the location of anodes, and the black (−) sign indicates the location of cathodes. The yellow strips indicate the location of the ZnO nanostructure patterns. The red dashed rectangles indicate the ZnO nanochannels, which are fabricated by covering ZnO nanostructures with a flat PDMS surface.
