Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

The present invention relates to a method for manufacturing a microneedle-based diagnostic skin patch coated with an aptamer, the method comprising a step for treating the surface of a microneedle with a base to modify the surface with a carboxyl group, and binding an aptamer having an amine group. A patch according to the present invention is advantageous in that a large number of aptamers, which are much smaller in size than antibody materials, can be attached to a relatively large number of microneedle tip surfaces. In addition, since aptamers for various kinds of biomarkers can be attached at the same time, various kinds of materials can be detected simultaneously (multiplexing), and thus even a microneedle tip-based skin patch can be used as a protein chip using aptamers.
