Single-sided optoelectrowetting (SSOEW)-configured substrates are provided, as well as microfluidic devices that include such substrates. The substrates can include a planar electrode, a photoconductive (or photosensitive) layer, a dielectric layer (single-layer or composite), a mesh electrode, and a hydrophobic coating. Fluid droplets can be moved across the hydrophobic coating of such substrates in a light-actuated manner, upon the application of a suitable AC voltage potential across the substrate and the focusing of light into the photoconductive layer of the substrate in a location proximal to the droplets. Walls can be disposed upon the substrates to form the microfluidic devices. Together the walls and substrate can form a microfluidic circuit, through which droplets can be moved. 提供配置有单面光电润湿(SSOEW)的基底，以及包括该基底的微流体器件。基底可以包括平面电极、光电导(或感光)层、电介质层(单层或复合)、网状电极和疏水涂层。当在基底上施加适当的AC电压电势且将光聚焦到基底的靠近液滴的光电导层中时，可以用光致动方式使流体液滴跨越这种基底的疏水涂层而移动。壁部可以设置在基底上方，以形成微流体器件。壁部与基底可以起形成微流体回路，液滴可以通过该微流体回路而移动。
