Abstract: A process for producing a functional molecule includes a forming step which forms a modified nucleotide n-mer (where, n represents an integer) containing a modified nucleoside prepared by introducing a substituent into a nucleoside composing a nucleic acid; and a producing step which produces a modified oligonucleotide sequence by randomly polymerizing the modified nucleotide n-mer. A preferable embodiment thereof includes a selecting step which selects a sequence having an affinity to a target from the modified oligonucleotide sequence, a determining step which amplifies the selected modified oligonucleotide sequence and determines the base sequence thereof, and a translating step which translates the sequence of the modified oligonucleotide sequence on the basis of a relation table prepared by relating at least one of 4n kinds of nucleotide n-mers, which are presented in the relation table prepared by the one-to-one combination of 4 kinds of nucleosides, to a modified nucleotide n-mer.

Abstract: The present invention provides, for example, a target detecting device comprising a target capturer, means for releasing the target capturer, light irradiating means and light detecting means, the target capturer at least partially containing a region interactive with an electrically conductive member, being capable of capturing a target, and being capable of emitting light upon irradiation with light in the case of not interacting with the electrically conductive member, the means for releasing the target capturer serving to release the target capturer from the electrically conductive member by ceasing the interaction between the target capturer and the electrically conductive member, the light irradiating means serving to apply light to the electrically conductive member, and the light detecting means serving to detect light emitted by the target capturer upon irradiation of light applied by the light irradiating means.

Abstract: A molecule-releasing apparatus includes a releasing unit configured to release molecules, wherein the releasing unit comprises at least one conductive member and releases molecules electrically interacting with the conductive member to which a potential is applied, from the conductive member by changing the potential so as to remove the interaction. In a moleculue-releasing method, molecules electrically attracted to two or more conductive members are released by electrical repulsion from the conductive members at different times. The molecule-releasing apparatus and molecule-releasing method are capable of efficiently releasing or transferring various useful molecules such as DNA molecules, into targets such as cells and can be safely applied for use in gene therapy and other applications.

Abstract: An analyte evaluating device is provided that comprises a carrier body that can be bound with an analyte having a fluorescence-labeled part that can emit fluorescence by light received when the distance between the fluorescence-labeled part and the carrier body is enlarged, wherein the distance between the fluorescence-labeled part and the carrier body can be varied by a responding part equipped on at least one of the analyte and the carrier body. It is possible to perform a high-sensitivity evaluation without introducing a fluorescence-labeled part or a radioactive material into an evaluation object. Evaluation is possible for a very small amount of sample. Furthermore, evaluation is possible even when multiple types of evaluation objects are present in a mixture. Miniaturized, complex, and integrated analyte evaluating devices can be provided.

Abstract: A first layer is disposed on the principal surface of a substrate. An adhesive layer made of Si containing fluorocarbon is disposed on the first layer. A second layer is disposed on the adhesive layer. One of the first and second layers is made of a material selected from a group consisting of a material whose main component is Si containing inorganic material, a metal, and an inorganic metal compound, and the other is made of an organic insulating film. Tight contactness of the organic layer to the layer whose main component is inorganic material can be improved.
