Title: DIELECTRIC CONSTANT MICROSCOPE AND METHOD OF OBSERVING ORGANIC SPECIMEN
Abstract:
Provided are a microscope and an observation method with which it is possible to observe the shape of a very small organic specimen. This dielectric constant microscope includes: first and second insulating thin films disposed facing one another in such a way as to sandwich a solution together with an organic specimen; application-side electrically conductive thin films P1 to Pn (where n is an integer > 1) provided spaced apart from one another regularly on an outward facing surface side of the first insulating thin film; and measuring-side electrically conductive thin films p1 to pm (where m is an integer > 1) provided spaced apart from one another regularly on an outward facing surface side of the second insulating thin film. Input signals Sf1 to Sfn having electric potentials that vary with mutually different frequencies are applied respectively to the application-side electrically conductive thin films P1 to Pn, electric potential variations are measured for each of the measuring-side electrically conductive thin films p1 to pm and are separated by being matched to said frequencies to obtain a dielectric constant distribution between the first and second insulating thin films from which the organic specimen is visualized.
