Title:
MICRONEEDLE STRUCTURE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/211059
Kind Code:
A1
Abstract:
This microneedle structure 10 comprises needle-shaped sections 12 on one surface side of a substrate 11, the substrate 11 is permeable by a liquid in the thickness direction, the needle-shaped sections 12 are formed from a composition including a low-melting-point resin with a melting point of 150ºC or less, and holes 13 are formed in the surface and the interior of the needle-shaped sections 12. In addition, a method for producing the microneedle structure 10 includes a bonding step in which the composition including a low-melting-point-resin with a melting point of 150ºC or less is heated and the heated low-melting-point resin and the substrate 11 are bonded. In this way, the present invention provides a microneedle structure and a method for producing the microneedle structure in which the effect of high temperatures on a substrate is reduced and there is a high degree of freedom in terms of the selection of the substrate.
