Abstract: In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of 2-phenoxyethanol of the user and is obtained by a sensor that detects 2-phenoxyethanol released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of 2-phenoxyethanol per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of 2-phenoxyethanol of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

Abstract: In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of benzyl alcohol of the user and is obtained by a sensor that detects benzyl alcohol released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of benzyl alcohol per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of benzyl alcohol of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

Abstract: The present invention provides a method for detecting an analyte with high sensitivity. In the present method, a solution is supplied onto a substrate comprising a first electrode and a second electrode. Then, an alternating voltage is applied between the first electrode and the second electrode to aggregate, onto the surface between the first electrode and the second electrode by dielectrophoresis, bioparticles and dielectric particles contained in the solution. The aggregated bioparticles are broken to release the analyte contained in the bioparticles. The released analyte is bound to a first antibody and a second antibody to cause the dielectric particles to be immobilized onto the substrate through formation of a sandwich structure composed of the first antibody, the analyte, and the second antibody. Finally, the analyte is detected through the fluorescent substance contained in the immobilized dielectric particles.
