    • Fluorescently marked targets bind to a substrate (230) synthesized with polymer sequences at known locations. The substrate (230) is mounted on an x-y-z translation table (240) during detection. The targets are detected by exposing selected regions of the substrate (230) to light from a light source (100) and detecting the light photons fluoresced therefrom, moving the substrate (230) position, and repeating the exposure and detection steps until the substrate (230) has been completely examined. The device includes a controller (190) for controlling the x-y-z translation table (240) movement for exposure of the selected regions of the substrate (230), the detection of the fluoresced light, and positioning of the substrate (230) to provide proper focusing of the light on the substrate (230) for maximum sensitivity. The resulting data can be used to determine binding affinity of the targets to the specific polymer sequences.
    • 荧光标记的靶结合到在已知位置处与聚合物序列合成的底物(230)。 在检测期间,将衬底(230)安装在x-y-z平移台(240)上。 通过将衬底(230)的选定区域暴露于来自光源(100)的光并检测从其发荧光的光子,移动衬底(230)位置并重复曝光和检测步骤直到衬底( 230)已经完全检查。 该装置包括控制器(190),用于控制用于曝光衬底(230)的选定区域的xyz平移台(240)运动,荧光灯的检测和衬底(230)的定位以提供适当的聚焦 的基板(230)上的光以获得最大的灵敏度。 所得数据可用于确定靶向特定聚合物序列的结合亲合力。
