Abstract:
1. A molecule-responsive gel particle changing in volume in response to a target molecule, comprising: a polymer gel particle; and a plurality of clathrate compound-forming host molecules fixed to the polymer gel particle by chemical bond, the polymer gel particle being obtained by emulsion polymerization of a monomer having a single polymerizable C═C double bond and a crosslinking monomer having two or more polymerizable C═C double bonds and an alkylene glycol chain of general formula (1) where R is ethylene, propylene, or tetramethylene and may or may not vary from one RO repeat unit to another, and n is an integer from 3 to 13, the plurality of host molecules being at least one or more types of molecules selected from the group consisting of cyclodextrin, crown compounds, cyclophane, azacyclophane, calixarene, and derivatives thereof.
