PHOTOCLEAVABLE LINKER FOR CATCHING AND/OR RELEASING OF CIRCULATING TUMOR CELLS OR EXTRA CELLULAR VESICLES
A photocleavable heterobifunctional linker can include a structure of Formula (A) wherein coumarin is any coumarin or coumarin derivative; R, R.sup.9, and R.sup.10 are each independently a chemical moiety; R.sup.1 is a hydrogen, protecting group, leaving group, substrate, or capture entity; R.sup.2 is a hydrogen, hydroxyl, halide, alkoxy, anhydride, amino, protecting group, leaving group, substrate, or capture entity; L.sup.1 is a sub-linker; and L.sup.2 is a sub-linker. A capture device can include the photocleavable bifunctional linker having a structure of Formula (A) as provide herein, wherein R.sup.1 is a substrate. A method of capturing a target substance can include: providing the capture device having the photocleavable bifunctional linker with the structure of Formula (A) and contacting a target substance to the capture moiety such that the target substance is captured. Irradiating the linker with light can cleave the linker, thereby releasing the target substance from the substrate.
SOLID PHASE CARRIER, LIGAND-BOUND SOLID PHASE CARRIER, METHOD FOR DETECTING OR SEPARATING TARGET SUBSTANCE, AND METHOD FOR PRODUCING SOLID PHASE CARRIER
Provided is a solid phase carrier which has high water dispersibility, allows facilitated binding of a ligand to a reactive functional group, and exhibits suppressed non-specific adsorption, and with which, in the case of using the solid phase carrier by having a ligand bound thereto, for example, detection of a target substance can be carried out with high sensitivity and low noise. Disclosed is a solid phase carrier having bound thereto a polymer including a structural unit represented by the following Formula (1) and a structural unit represented by the following Formula (2):
##STR00001##
wherein in Formula (1), R.sup.1 represents a hydrogen atom or a methyl group; and R.sup.2 represents an organic group having a zwitterionic structure,
##STR00002## in Formula (2), R.sup.3 represents a hydrogen atom or a methyl group R.sup.4 represents —(C═O)—O—*, —(C═O)—NR.sup.6—* (wherein R.sup.6 represents a hydrogen atom or a methyl group; and the symbol * represents a position of bonding to R.sup.5 in Formula (2)), or a phenylene group; in a case in which R.sup.4 represents —(C═O)—O—*, R.sup.5 represents a hydrogen atom, or an organic group having a reactive functional group, and in a case in which R.sup.4 represents —(C═O)—NR.sup.6—* or a phenylene group, R.sup.5 represents an organic group having a reactive functional group, provided that R.sup.5 is not an organic group having a zwitterionic structure.

METHOD OF FABRICATING SUBSTRATE FOR ANALYSIS, SUBSTRATE FOR ANALYSIS, AND ANALYSIS UNIT
A method of fabricating a substrate for analysis fixes antibodies that specifically react with specific antigens included in detection target substances to the substrate for analysis. The method subjects the substrate for analysis to immersion treatment with a predetermined treatment solution so as to form antibody aggregations in which the antibodies are aggregated at boundary regions between recesses and convex portions on the substrate for analysis. The method causes the antigens and the antibodies to react with each other so as to capture the detection target substances on the substrate for analysis by the antibody aggregations.
