摘要:
The application discloses a method to fabricate microneedle patches, comprising a) casting (painting and pasting) an aqueous polymer solution on a mold of array of micro-holes which is made of porous materials b) sucking the polymer solution into the micro-holes by applying vacuum at the back of the mold d) freezing and thawing the casted polymer solution to induce gelation and e) drying the gelled polymer solution. Specifically, the present invention describes a process and composition of polymeric microneedlepatch which overcomes the limitations of existing microneedles systems and may be used for transdermal delivery system for therapeutics and other applications.
