Abstract
In an aspect, a sensor includes a combining portion 240 that combines with a second substance 220 having a molecular weight larger than a molecular weight of a first substance 210. Further, in an aspect, the sensor includes a substrate 10 including a surface on which the combining portion 240 is disposed, the combining portion 240 detecting whether or not the first substance 210 is included in an analyte that has come into contact with both an aptamer 230 including a first combining part 231 for the first substance 210 and a second combining part 232 for the second substance 220 and being combined with either of the first substance 210 and the second substance 220 and the second substance 220.
Claims15
A sensor, comprising:
- a substrate comprising a combining portion;
- and
- an aptamer combined with the combining portion before a first contact with an analyte that contains a first substance and combined with the first substance after the first contact with the analyte.
A method for detecting a first substance, comprising:
- preparing a substrate comprising a combining portion that is combined with an aptamter;
- causing the substrate to contact an analyte comprising a first substance;
- and
- detecting a change in a surface state of the substrate as a result of transferring the aptamer from the combining portion to the first substance.
