AI Technical Summary
Conventional methods for producing microneedle patches for transdermal drug delivery are labor-intensive, costly, and limited in producing microneedles with desired size and geometry, lacking the efficiency and accessibility required for fast and low-cost production.
The use of vat photopolymerization 3D printing techniques, specifically DLP, with Gelatin Methacrylate (GelMA) or a mixture of GelMA and Keratin Methacrylate (KerMA) or other methacrylated polymers, allowing for the design and production of hydrogel microneedles with precise geometry and high resolution, enabling rapid, cost-effective, and biocompatible microneedle patch manufacturing.
This method enables the production of hydrogel microneedles with high mechanical strength, adjustable drug release rates, and enhanced bioavailability, overcoming the limitations of conventional methods by providing a fast, easy, and low-cost solution for transdermal drug delivery with improved microneedle properties and patient convenience.
