This invention provides a method of screening or patterning a biomaterial in terms of their specificities to sugar chains by performing real-time and comprehensive measurement of an interaction between sugar chains and the biomaterial concurrently with a very small amount of the biomaterial without labeling. It is a method of measuring an interaction between a biomaterial and a sugar chain(s), the method including: bringing a solution containing the biomaterial in contact with a ligand carrier, the ligand carrier including a support whose surface includes a metal, and a ligand conjugate(s) immobilized independently on the surface, the ligand carrier carrying the ligand conjugate(s) in such a manner that 1 to 500 kinds of the ligand conjugate(s) is immobilized per cm<SUP>2</SUP>, and each ligand conjugate having a structure in which a sugar chain is bonded with a linker compound having a sulfur atom, and the biomaterial being at least one selected from the groups of proteins, viruses, cells, microorganisms, liposome, and micelles.
