Development of Specially Designed Nanoparticle‐coated 3D‐printed Gelatin Methacryloyl Patches for Potential Tissue Engineering Applications

Macromolecular Materials and Engineering, Volume 310, Issue 2, February 2025.
This study aims to design a unique tympanic membrane (TM) patch model for tissue engineering of TM perforations. The edges of the patch are donated with microneedles (MNs) for improved attachment to the perforation site. Gelatin methacryloyl (GelMA)‐based TM patches are fabricated using the digital light processing (DLP) based 3D printing technique. To
