Abstract: An emotion-inducing device includes an inference means that infers a current emotion and an analysis means that obtains, based on a database, odor information bringing the current emotion closer to an expected emotion. The database associates an odor component with an induced emotion that can occur due to the odor component. The emotion-inducing device may further include an emission means that emits at least one type of odor component based on the odor information. The database is configured such that odor components are arranged in association with respective induced emotions. In this case, two or more index values (axes) that can compartmentalize emotions may be used. The emotion-inducing device is realized so that a computer that executes programs is made to cooperate with measurement equipment and odor emission equipment.

Abstract: A complex includes photoresponsive liposomes, a first buffer solution, and a second buffer solution. Each of the photoresponsive liposomes includes a membrane that contains azobenzene compound and phospholipid and a membrane binding site that is immobilized to the membrane and bindable to a target substance. The first buffer solution is filled inside the photoresponsive liposomes. The second buffer solution exists outside of the photoresponsive liposomes. The first buffer solution has a composition that is different from that of the second buffer solution.
