Gelatin microparticles are made of gelatin, a food ingredient derived from collagen, which has biocompatibility.
Gelatin Microparticles are polymer microparticles constructed of gelatin. Gelatin or gelatine (from Latin: gelatus meaning "stiff" or "frozen") is a translucent, colorless, flavorless food ingredient, commonly derived from collagen taken from animal body parts. Gelatin microparticles have an array of applications in research science due to their biocompatibility and controlled release systems.
