Abstract: A first sample solution including exosomes including first to third detection target substances is mixed with a first buffer solution including first nanoparticles including first binding substances which bind to the first detection target substances. The first detection target substances and the first binding substances are bound together, so as to form first complexes of the exosomes and the first nanoparticles. The first complexes are isolated from a mixed solution of the first sample solution and the first buffer solution. The second detection target substances and the second binding substances are bound together, so as to capture the first complexes on a substrate. The second binding substances are fixed onto the substrate. A second buffer solution including second nanoparticles including third binding substances which bind to the third detection target substances is reacted with the first complexes.
Abstract: Even when digital media of the respective devices are not media of common codec, the digital media can be reproduced in other device. A digital medium is provided to a providing destination device which reproduces the digital medium upon receiving it. Before providing the digital medium, a codec which can be used in the providing destination device is reported to the providing source device (step 22). The provision of the digital medium is directly performed without performing conversion if the codec is a predetermined common codec. If the codec is not the common codec, it is converted into a medium format of the common codec. Alternatively, if the codec can be used by the providing destination device, the codec is directly used in the medium format (steps 23-26).
