Patent ID: 7932046

Claim:
A method for detecting a biomaterial, which comprises the steps of: (S 1 ) immobilizing polydiacetylene liposomes onto a substrate; (S 2 ) linking the polydiacetylene liposomes together and layering them on the substrate, wherein the polydiacetylene liposomes are interlinked together by an interlinker comprising one or more functional groups selected from the group consisting of sulfone, amine and carboxyl group; (S 3 ) immobilizing a material which forms a complementary binding with a subject biomaterial to be detected onto the polydiacetylene liposomes; (S 4 ) exposing the resulted polydiacetylene liposomes to UV light, giving them a blue color, so as to form a chip for biomaterial detection; (S 5 ) applying the subject biomaterial to be detected to the chip for biomaterial detection for reaction; and (S 6 ) measuring a fluorescent signal from the chip for biomaterial detection.
