The invention includes compositions, devices, and methods for analyzing a polymer and/or polymer unit. The polymer may be a homo or hetero-polymer such as DNA, RNA, a polysaccharide, or a peptide. The device includes electrodes that form a tunnel gap through which the polymer can pass. The electrodes are functionalized with a reagent attached thereto, and the reagent is capable of forming a transient bond to a polymer unit. When the transient bond forms between the reagent and the unit, a detectable signal is generated and used to analyze the polymer.
该发明包括用于分析聚合物和/或聚合物单元的组合物、设备和方法。该聚合物可以是同聚物或异聚物,如DNA、RNA、多糖或肽。该设备包括形成隧道间隙的电极,聚合物可以通过该间隙。电极经功能化处理,附有试剂,该试剂能够与聚合物单元形成瞬时键。当试剂与单元之间形成瞬时键时,会产生可检测的信号,用于分析聚合物。
