Abstract: The present invention relates to a colorimetric detection of a target material based on a hydrogel particle. A colorimetric detection of a target material based on a hydrogel particle according to the embodiment of the present invention comprises the steps of: reacting a sample containing the target material with the hydrogel particle, which is loaded on the inside with a probe that specifically binds to the target material; and accumulating and amplifying an insoluble colorimetric material in the hydrogel particle so as to label the target material bound to the probe. Here, the hydrogel particle is made of a polymer network, the probe is loaded by binding to the polymer network, and the insoluble colorimetric material is fixed to the polymer network.
