Summary:To provide microfluidic devices that include a substrate having an optically-actuated electrokinetic configuration.SOLUTION: A microfluidic device can include a base an outer surface of which forms one or more enclosures for containing a fluidic medium. The base can include an array of individually controllable transistor structures each of which can comprise both a lateral transistor and a vertical transistor. The transistor structures can be light activated, and the lateral and vertical transistors can thus be phototransistors. Each transistor structure can be activated to create a temporary electrical connection from a region of the outer surface of the base to a common electrical conductor. The temporary electrical connection can induce a localized electrokinetic force generally at the region, which can be sufficiently strong to move a nearby micro-object in the enclosure.SELECTED DRAWING: Figure 3A 【課題】光学的に作動する界面動電構成を有する基板を含むマイクロ流体デバイスを提供する。【解決手段】マイクロ流体デバイスは、ベース部分を含み、ベース部分の外面は、流体媒体を包含するための１つまたは複数のエンクロージャを形成する。ベース部分は、個々に制御可能なトランジスタ構造のアレイを含み、トランジスタ構造のそれぞれは、横方向トランジスタおよび垂直方向トランジスタの両方を含むことができる。トランジスタ構造は光で活性化され得、かつ横方向および垂直方向トランジスタは、したがってフォトトランジスタであることができる。各トランジスタ構造は、ベース部分の外面の領域から共通の電気導体までの一時的な電気接続を生成するように活性化され得る。一時的な電気接続は、概ねその領域で局所的な界面動電力を誘起することができ、この局所的な界面動電力は、エンクロージャ内の近くの微小物体を移動させるのに十分な強さであり得る。【選択図】図３Ａ
