Abstract

An embodiment of the present disclosure provides a microfluidic chip, including: a first substrate; wherein the first substrate includes a first base, a first electrode layer on the first base; the first electrode layer includes a plurality of first electrodes at intervals along a first direction, wherein a cross-sectional shape of the first electrode parallel to the first base is a centrosymmetric shape, and the cross-sectional shape includes: a first boundary and a second boundary opposite to each other in the first direction; a shape of the first boundary is a centrosymmetric curve, a distance between two end points of the first boundary in a second direction perpendicular to the first direction is less than a length of the first boundary; the second boundary has a same shape and length as the first boundary, and the first and second boundaries are parallel to each other in the first direction.
