    Abstract: An optical interferometer includes: a light source that emits a coherent first beam and a second beam that has a frequency difference corresponding to the natural frequency of a target molecule; amplitude modulating means that modulates the amplitude of the second beam; splitting means that splits the first beam into a reference beam and a first applied beam; optical path length adjusting means that adjusts the optical path length of the reference beam; and detecting means that detects an interference pattern between the reference beam and the first beam (a signal beam) that has experienced a stimulated Raman loss or gain in accordance with the amplitude modulation as a result of the frequency difference resonating with the target molecule when the first applied beam and a second applied beam (the amplitude modulated second beam) have been applied to a measurement position of an object.

    Abstract: The present invention provides a method for detecting an interaction, which method can solve not only the problem of false negatives but also the problem of false positives. This method is a method for detecting a protein(s) that interact(s) with a target substance(s), the method comprising repeating a (1) transcription step, (2) assignment step, (3) selection step, and (4) amplification step, wherein: (a) in each of a plurality of times of preparation of a cDNA library among the initial preparation of a cDNA library and the round(s) of preparation of a cDNA library in the later amplification step(s), the cDNA library is prepared using a primer(s) having a sequence(s) specific to the time of preparation; (b) the cDNA libraries prepared using the primers having sequences specific to the times of preparation are mixed, and sequences in the cDNA library mixture are determined; (c) the determined sequences are subjected to measurement of the number(s) of molecules encoding the same candidate protein(s) for each time of preparation based on the sequence(s) specific to the time of preparation; and (d) a candidate protein(s) encoded by a molecule(s) that significantly increase(s) as the preparation rounds proceed is/are detected as the protein(s) that interact(s) with the target substance(s).

    Abstract: A power generator includes a power generating unit and at least one of a power storage unit or an output unit that is electrically connected to the power generating unit. The power generating unit includes an electret having a first charged surface and a second charged surface that are charged with opposite polarities, a first electrode formed on the first charged surface, and a second electrode formed on the second charged surface. The electret is formed by polarizing an electret material that includes an inorganic dielectric having a bandgap energy of 4 eV or more. At least one of the first electrode or the second electrode are partially disposed on the corresponding charged surface such that at least one of the first charged surface or the second charged surface has a portion as a current collecting surface exposed outward.
