Abstract: A liposome composition capable of including a chemical substance such as an electrochemiluminescent substance in an internal aqueous phase of the liposome at a higher concentration, and a production method thereof, as well as an analytical method of an analyte that enables an analyte to be analyzed with a high sensitivity using the liposome composition are provided. In a liposome composition containing a liposome, and a chemical substance enclosed in an internal aqueous phase of the liposome, a lipid bilayer composing the liposome has a positive or negative charge, and the chemical substance has a charge opposite to the charge of the lipid bilayer.

Abstract: A gene detection method for detecting a gene having a specific sequence with high sensitivity is provided.

Abstract: A method for determining the concentration of dioxins present in a sample comprises the steps of chemically linking a hapten having a structure mimic to a part of the structures of dioxins with a ruthenium complex to thus form an antigen; incubating the resulting antigen together with an antibody fixed to or immobilized on an electrode to thus induce an antigen-antibody reaction; oxidizing or reducing the ruthenium complex by applying an electric voltage to the reaction product through the electrode to thus induce electrolytic light emission; and observing the electrolytically emitted light rays to quantitatively determine the amount of the antigen and to thus evaluate the concentration of the dioxins present in the sample. The present invention permits the elimination of the use of any reagent such as hydrogen peroxide required for the chemical luminescence, the highly sensitive analysis of dioxins and the miniaturization of the device to be used in the analysis of dioxins.
