Abstract: The present disclosure relates to a minimally-invasive skin biopsy method. The minimally-invasive skin biopsy method according to the present disclosure includes: preparing a microneedle patch; attaching the microneedle patch to a skin of an object; maintaining a state in which the microneedle patch is attached to the skin of the object for a predetermined period of time; and detaching the microneedle patch from the skin of the object after the predetermined period of time, and analyzing a protein component of the object, which adheres to a microneedle of the microneedle patch. The microneedle is made of a biocompatible polymer substance.
