Zusammenfassung:	Provided herein is a composition comprising a plurality of microneedle particles (100) and a liquid medium in which the plurality of microneedle particles (100) is dispersed. The composition is adapted for application to a biological tissue surface. Each of the microneedle particles (100) comprises a core structure (110) and one or more microneedles (120) extending from the core structure. The microneedles (120) are structured to penetrate the biological tissue surface. At least one of the core structure (110),the one or more microneedles (120), and a spatial relationship between/among two or more of the microneedles (120) is configured to prevent the entire microneedle particle (100) from penetrating the biological tissue surface.
