| 发明名称 | Sample analysis method | ||
| 摘要 | The analysis method allows analysis of samples with high sensitivity, irrespective of interelectrode distance. The method includes: a step of applying a voltage between a first electrode pair such that an electric field is formed in a direction intersecting a migration direction of a sample; a step of placing a solution, including an electrochemically active molecule that produces a redox reaction at the electrode pair, between the first electrode pair; a step of causing the sample to migrate; and a step of measuring an amount of change in current flow between the first electrode pair. | ||

| 主权项 | 1. A sample analysis method, comprising: (a) applying a voltage between a first electrode pair, which is formed so as to sandwich a migration pathway of a sample such that an electric field is formed in a direction intersecting a migration direction of the sample; (b) causing a first current, which arises from a redox reaction, to flow to the first electrode pair by placing, within the migration pathway interposed between the first electrode pair, a solution including an electrochemically active molecule that produces the redox reaction at the first electrode pair; (c) causing the sample to migrate along the migration pathway interposed between the first electrode pair; and (d) measuring an amount of change in the first current produced by migration of the sample. | ||
