Abstract
The present disclosure relates to a gel-phase patch that performs a function of assisting in staining during a staining process such as a process of coming into contact with a specimen such as blood to perform a staining function of staining the specimen, a process of fixing the specimen, or a process of forming an optimal pH at a specimen stained by a staining sample. According to an aspect of the present disclosure, a contact-type staining patch includes a staining solution that reacts with a specimen and a gel receptor provided as a gel matrix of a mesh structure in which a pore that accommodates the staining solution is formed and the mesh structure prevents the staining solution in the pore from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer some of the staining solution to the specimen.
