摘要： Provided is a method for detecting an antigen without use of a labeled-antibody. A support having an antibody and a multi-copper oxidase CueO immobilized thereon is brought into contact with a first buffer solution containing the antigen, a current is measured by a potentiostat method using the support and a second buffer solution, and when the measured current is greater than or equal to 1.5×(blank value), it is determined that the antigen exists. The second buffer solution contains a substrate of the CueO and has an ionic strength falling within a range of not less than 0.3 mM and not more than 1.0 mM.

摘要： The present invention relates to a method for detecting an antigen with use of an antibody and an enzyme. Specifically, the present invention provides a method for detecting an antigen without use of a labeled-antibody. the method comprises immersing particles in a first buffer solution which is predicted to contain the antigen; wherein an antibody and a multi-copper oxidase CueO are immobilized on each surface of the particles, and the antibody reacts specifically with the antigen. The method further comprises the following steps recovering the obtained particles; mixing the particles recovered, an oxidation-reduction indicator (reductant), and a second buffer solution so as to prepare a reaction solution; measuring an activity degree of the multi-copper oxidase CueO contained in the reaction solution; determining that the first buffer solution contains the antigen based on the above activity degree.

摘要： The present invention provides a method for production of a single electron semiconductor element (SET) in which a quantum dot is selectively arranged in a nano gap between fine electrodes, whereby the product yield is significantly improved, leading to excellent practical applicability. The method for production of SET of the present invention is characterized in that a solution containing ferritin including a metal or semiconductor particle therein, and a nonionic surfactant is dropped on a substrate having a source electrode and a drain electrode formed by laminating a titanium film and a film of a metal other than titanium, whereby the ferritin is selectively arranged in a nano gap between the source electrode/drain electrode. In the method for production of SET of the present invention, the metal or semiconductor particle can be fixed as a quantum dot at a suitable position in the nano gap between the source electrode/drain electrode following decomposition of ferritin, and in addition, formation of unnecessary quantum dot can be suppressed.

摘要： An object of the present invention is to provide a method of forming fine particles on a substrate in which reoxidization of reduced fine particles is suppressed. Reduced fine particles (FeO fine particles) are formed by embedding metal oxide fine particles (Fe2O3 fine particles) fixed on a p type silicon semiconductor substrate into a silicon oxidized film, and carrying out a heat treatment in a reducing gas atmosphere. Presence of the silicon oxidized film enables suppression of reoxidization of the reduced fine particles (FeO fine particles) due to exposure to the ambient air.
