    • We disclose a method of screening a mammal for a cancer associated with methylation of promoters of tumor-suppressor genes by collecting a sample of a body fluid or tissue of the mammal containing free DNA; isolating the free DNA from the sample; amplifying at least a portion of the promoter of each of a plurality of turner-suppressor genes associated with the cancer from the free DNA, to yield a plurality of amplified promoters; and quantifying methylation of each of the plurality of amplified promoters, to yield a methylation quantity. The method can have a high sensitivity and high specificity and can thus reduce the proportion of unneeded biopsies. It can also be performed with minimal invasiveness and discomfort to a patient.
    • 我们公开了通过收集含有游离DNA的哺乳动物的体液或组织的样品来筛选哺乳动物与肿瘤抑制基因启动子的甲基化相关的方法; 从样品中分离游离DNA; 从游离DNA扩增与癌症相关的多个转移抑制基因中的每一个的至少一部分启动子,以产生多个扩增的启动子; 并定量多个扩增的启动子中的每一个的甲基化,以产生甲基化量。 该方法可以具有高灵敏度和高特异性,因此可以减少不需要的活组织检查的比例。 它也可以以最小的入侵和对患者的不适进行。

    • A biosensor capable of detecting the presence and/or concentration of an analyte or biomarker includes at least one electrically conductive electrode operatively coupled to an impedance analyzer for measuring the change in the resistive impedance of the electrode in response to an applied alternating current at a plurality of frequencies. In one embodiment, at least one electrode is covered with a self-assembled monolayer that is chemically bonded to a surface. A plurality of virus particles such as phage viruses are immobilized on the self-assembled monolayer and may be exposed to a test or sample solution. The virus particles may be obtained from phage-displayed libraries to detect a wide variety of targets including, for example, DNA, RNA, small molecules, and proteins or polypeptides. In another embodiment, the virus particles are electrostatically bound to a substrate in between a pair of elongated electrodes disposed on a substrate.
    • 能够检测分析物或生物标志物的存在和/或浓度的生物传感器包括可操作地耦合到阻抗分析器的至少一个导电电极,用于响应于多个施加的交流电流来测量电极的电阻阻抗的变化 的频率。 在一个实施方案中,至少一个电极被化学键合到表面的自组装单层覆盖。 多个病毒颗粒如噬菌体病毒固定在自组装单层上,并可暴露于测试或样品溶液中。 病毒颗粒可以从噬菌体展示的文库中获得,以检测多种靶,包括例如DNA,RNA,小分子和蛋白质或多肽。 在另一个实施方案中,病毒颗粒在布置在基底上的一对细长电极之间静电结合到基底上。
