DEVICE FOR SAMPLE ANALYSIS AND METHOD FOR EXOSOME CAPTURE

摘要

A recessed and protruding structure (20) including recessed portions (20a) and protruding portions (20b) arranged periodically is formed in a base portion made of synthetic resin or the like. In the recessed portions (20a), antibodies (60) which bind to antigens (52) existing in exosomes (50) to be detected are immobilized and are caused to bind to the exosomes (50). The exosomes (50) are thereby immobilized in the recessed portion (20a).
