Abstract
The invention provides molecule-responsive gel particles which change in size in response to specific molecules and a method of production of the same. A polymer gel particle with a crosslinked structure has fixed thereto a plurality of clathrate compound-forming host molecules. two or more of the plurality of host molecules clathrate different atomic groups in a target molecule so that the two or more host molecules and the target molecule can form a crosslink in the molecule-responsive gel particle.

- —(RO)— (1)
- where R is an alkylene group of a carbon number 1 to 6 and may or may not vary from one RO repeat unit to another, and n is an integer from 3 to 13.

A method of producing molecule-responsive gel particles, comprising:
- the reactive-functional-group-introducing step of introducing reactive functional groups to at least one type of host molecules;
- and
- the polymerization step of emulsion polymerizing a polymer-gel-fine-particle forming monomer having a single polymerizable C═C double bond in the presence of a crosslinking monomer and the reactive-functional-group-introduced host molecules obtained in the reactive-functional-group-introducing step so as to obtain molecule-responsive gel particles,
- the crosslinking monomer having two or more polymerizable C═C double bonds and an alkylene glycol chain of general formula (1)
- —(RO)n— (1)
- where R is an alkylene group of a carbon number 1 to 6 and may or may not vary from one RO repeat unit to another, and n is an integer from 3 to 13.
