An optically controlled microfluidic chip is provided for administering a fluid to a neuronal site. The chip is made of at least one unit or pixel, each of which constitutively emits fluid in the dark, and reduces emission of fluid in response to light. The individual pixels are capable of being individually controlled, thereby translating a spatial pattern of incident light into a spatial pattern of neuronal stimulation. Each pixel contains a housing, an aperture in the housing, and a reservoir containing fluid that is connected to the aperture. The aperture is designed to allow continuous emission of fluid from the reservoir through the aperture when the pixel is in the dark. Each pixel also includes an optical control, which reduces the emission of fluid from the reservoir through the aperture in response to light.
提供了一种光学控制微流控芯片,用于向神经元部位注入液体。该芯片由至少一个单元或像素组成,每个单元或像素在黑暗中连续发射液体,在光照下减少液体发射。单个像素可单独控制,从而将入射光的空间模式转化为刺激神经元的空间模式。每个像素包含一个外壳、外壳上的一个孔和一个与孔相连的装有液体的储液器。开孔的设计目的是当像素处于黑暗状态时,贮液器中的液体能够通过开孔持续发射。每个像素还包括一个光学控制装置,该装置可在光照下减少贮液器中的流体通过光孔排出。
