20090088333TARGET MOLECULE EVALUATION METHOD AND APPARATUS - AC potential is applied between a substrate electrode provided on a substrate and a counter electrode, a sample is brought into contact with a probe molecule bound to the substrate electrode, and a fluorescent signal obtained from a fluorescent marker provided on the probe molecule is observed to evaluate a target molecule in the sample that has bound to the probe molecule, wherein the target molecule is evaluated by measuring a signal intensity and/or a signal amplitude.04-02-2009
20090130777METHOD FOR EVALUATING ANALYTE - 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.05-21-2009
20110100822Device and method for quantitatively determining an analyte, a method for determining an effective size of a molecule, a method for attaching molecules to a substrate, and a device for detecting molecules - A device for quantitatively determining an analyte is provided to conspicuously improve the performance of the quantitative determination. This device is equipped with a flow channel, an analyte detecting unit for capturing and detecting the analyte, and a quantitative measurement unit for quantitatively determining the analyte, wherein a signal generated when the analyte detecting unit has detected the analyte is divided into a plurality of parts in the direction of the flow in the flow channel at the quantitative measurement unit for processing. Also provided are technologies including one for controlling the density of molecules attached to the surface of a solid. In these technologies, when molecules are attached to a substrate, the density of attached molecules is controlled, by having an electrolyte also present in a solution containing the molecules to adjust the screening effect by the electrolyte, and by taking into consideration the effective size of a molecule.05-05-2011
