Abstract: The present invention has a subject of desorbing a target substance under mild elusion conditions in affinity purification using a low molecular weight ligand. In the present invention, a polar auxiliary group is introduced to a site adjacent to the low molecular weight ligand to perturb a pKa value of a functional group in the low-molecular-weight ligand, thereby ionizing the low molecular weight ligand under mild pH conditions.

Abstract: A method for manufacturing a metamaterial including an electromagnetic wave resonator that resonates with an electromagnetic wave is provided. In the method, a support including a portion where the electromagnetic wave resonator is to be formed is formed, and the electromagnetic wave resonator is arranged in the support by depositing a material to form the electromagnetic wave resonator on the portion of the support. The support is formed by forming a column structure of a hydrophilic/hydrophobic phase-separated film including a hydrophilic liquid phase area penetrating through in a thickness direction, by packing a filler into the column structure of the hydrophilic/hydrophobic phase-separated film including the hydrophilic liquid phase area so as to form the filler as high as the column structure, and by obtaining the support including the filler by removing at least a part of the hydrophilic/hydrophobic phase-separated film.
