    • Colorimetry is used to detect amplification reaction products. A sample is contacted with a reaction mix under conditions such that an amplification reaction occurs and produces an amplification reaction product if the sample contains a target nucleic acid template molecule. The reaction mix includes an enzyme for catalyzing the amplification reaction, and at least one halochromic agent. If the target nucleic acid template molecule is present, the amplification reaction changes the starting pH of the reaction mix to cause a detectable colorimetric change of the halochromic agent, thereby indicating the presence of the target nucleic acid. If the target nucleic acid template molecule is not present, the amplification reaction does not generate an adequate number of protons to sufficiently change the starting pH of the reaction mix to cause a detectable colorimetric change of the halochromic agent, thereby indicating that the amplification reaction product has not been produced.
    • 比色法用于检测扩增反应产物。 在发生扩增反应的条件下使样品与反应混合物接触,如果样品含有靶核酸模板分子,则产生扩增反应产物。 反应混合物包括用于催化扩增反应的酶和至少一种卤代色素。 如果存在靶核酸模板分子,则扩增反应改变反应混合物的起始pH,以引起卤色变色剂的可检测的比色变化,从而指示靶核酸的存在。 如果靶核酸模板分子不存在,则扩增反应不产生足够数量的质子,以充分改变反应混合物的起始pH,以引起卤色变色剂的可检测的比色变化,从而表明扩增反应产物 尚未制作。

    • Devices and methods for detecting a target molecule are provided herein. The methods entail contacting a sample with a polymer scaffold, the polymer comprising at least one association site configured to associate with the target molecule. The sample is brought into contact with the polymer to determine whether the target molecule is present in the sample under conditions allowing the target molecule, if present, to associate with the polymer scaffold. The methods further involve loading the polymer into a device comprising a pore or channel that connects two volumes, configuring the device to pass the polymer through the pore or channel from one volume to the other volume, and determining, with a sensor configured to detect objects passing through the pore or channel, whether the target molecule is associated with the association site, and thereby detecting the presence or absence of the target molecule in the sample.
    • 本文提供了用于检测靶分子的装置和方法。 所述方法需要使样品与聚合物支架接触,所述聚合物包含至少一个配位成与靶分子缔合的缔合位点。 使样品与聚合物接触以确定靶分子是否存在于样品中,允许目标分子(如果存在)与聚合物支架缔合的条件下。 所述方法还涉及将聚合物加载到包括连接两个体积的孔或通道的装置中,将所述装置配置成将所述聚合物通过所述孔或通道从一个体积传递到另一个体积,以及通过配置成检测物体的传感器来确定 通过孔或通道,靶分子是否与缔合位点相关联,从而检测样品中靶分子的存在或不存在。
