Figure 1. Fabrication strategies and biomedical applications of collagen microgels. Schematic illustration shows the diverse preparation techniques for collagen microgels, including mechanical force-driven methods (emulsification and fragmentation), spray-based manufacturing (spray drying and electrospraying), microfluidic platforms, and alternative approaches (membrane emulsification). The diagram also highlights their applications in regenerative medicine as delivery systems for cells, growth factors, and drugs; injectable micro-scaffolds for tissue repair; microgel inks for 3D printing; and matrices for organoid culture and tissue engineering.
