Abstract
Gelatin methacryloyl (GelMA) has emerged as a highly suitable material for microneedle (MN) fabrication, offering exceptional biocompatibility and cost-effectiveness. Despite significant advances introduced by GelMA hydrogels, research on GelMA MNs dates back to 2019, yet no review has specifically focused on the manufacturing techniques and mechanical properties of GelMA MNs. For the first time, this review aims to examine the manufacturing methods and mechanical characteristics of GelMA microneedles across various medical applications. Additionally, it discusses different approaches to mechanical characterization and identifies gaps in current manufacturing technologies. The review also explores the potential implications of GelMA MNs in drug delivery and disease diagnosis. Finally, additive manufacturing and hybrid methods, identified as the most promising techniques for future large-scale production, are proposed for further optimization.
