    • Methods and devices for detecting deposition unit misalignment, e.g., printhead misalignment, of an in situ polymeric, e.g., a nucleic acid, array synthesis device are provided. In accordance with the subject methods, at least one test probe feature is synthesized on a substrate using an in situ polymeric array, e.g., nucleic acid array or protein array, synthesis device. The at least one test probe feature is then contacted with at least two different distinguishably labeled targets, e.g., target nucleic acids. The binding of the targets to the at least one test probe feature is then evaluated to detect any misalignment, e.g., deposition unit or pulse jet misalignments, of the synthesis device. Also provided are substrates having at least one test probe feature and at least one polymeric array, as well as methods of using the substrates in array assays. Also included are kits for use in practicing the subject methods.

    • A method for reading out data from microlocations of a microelectronic array involves activating multiple microlocations in parallel and simultaneously detecting the responses from the activated microlocations to determine concentrations of molecular biological material at each microlocation. In a preferred embodiment, the microelectronic array includes electronically addressable electrodes at each microlocation which can be individually activated via a control system. An electrochemiluminescent detection technique is used to detect the presence and determine the concentration of bound molecular biological material that is located at each microlocation. Electrochemiluminescent material is utilized because it gives off light when excited by an applied electrical field. With an addressable microelectronic array, electrical fields can be applied to various combinations of microlocations simultaneously to allow readout of several microlocations in parallel. This is in contrast to the laser-based readout approach which applies activation energy to one microlocation at a time by impacting each microlocation with a single laser system. Reading out multiple microlocations simultaneously in accordance with the invention can produce significant time savings in large arrays.
    • 从微电子阵列的微位置读出数据的方法包括平行地激活多个微位点,同时检测来自活化微位点的响应,以确定每个微位置处的分子生物材料的浓度。 在优选实施例中,微电子阵列包括每个微位置处的可电子寻址电极,其可以经由控制系统单独激活。 电化学发光检测技术用于检测位于每个微位置的结合分子生物材料的存在和确定浓度。 使用电化学发光材料,因为当通过施加的电场激发时它发出光。 利用可寻址的微电子阵列,电场可以同时应用于微位置的各种组合,以允许并行读出几个微位置。 这与基于激光的读出方法相反,该方法通过用单个激光系统冲击每个微位置,一次将激活能量施加到一个微位置。 根据本发明同时读出多个微位置可以在大阵列中产生显着的时间节省。
