摘要： A method for evaluating a target molecule bound to a probe molecule provided with a marker includes: applying AC voltage between a working electrode provided on a substrate and a counter electrode; and using a signal obtained from the marker on the probe molecule bound to the working electrode when a frequency of the AC voltage is varied, or an average value of the signal, to determine at least one of a Stokes radius or molecular weight of the target molecule, a binding rate between the probe molecule and the target molecule, a binding rate constant therebetween, a dissociation rate therebetween, and a dissociation rate constant therebetween.

摘要： An object of the present invention is to provide a technique that can adjust a molecular density of the film of functional molecules (e.g. DNA molecules), which is utilized for biochips such as DNA chip, to a desired degree efficiently and easily. The method for producing a molecular film with an adjusted density according to the present invention includes forming a molecular film and adjusting a molecular density. In the forming a molecular film, a molecular film composed of molecules is formed on a conductive substrate, wherein the molecule includes a region capable of binding to the conductive substrate at least in a portion thereof. In the density adjusting, a molecular density of the molecular film is adjusted by desorbing a part of the molecules which make up the molecular film from the conductive substrate.

摘要： In an analyte evaluation method for evaluating an analyte, AC voltage is applied between a substrate electrode on a substrate and a counter electrode, and signals obtained from a marker provided on an analyte bound to the substrate electrode are observed, wherein the frequency of the AC voltage is changed and the behavior of the average value of the marker signals is observed. A novel, highly-selective, low-noise method of evaluating a object of evaluation is thus achieved.
