The process for producing crosslinked porcine gelatin microparticles, as depicted in the schematic in Figure , involved multiple steps to achieve a consistent particle size distribution, with additional images and size data provided in is given as volume density (%) across different size classes in micrometers, highlighting a predominantly uniform distribution. Smaller particles with an optimal surface area-to-volume ratio enhance interaction with the methacrylated fish gelatin matrix, providing improved mechanical reinforcement. This consistency is particularly beneficial for applications requiring stable and mechanically reinforced hydrogel structures, such as tissue engineering scaffolds and drug delivery systems.
