Injectable Multifunctional Sponges for advanced drug delivery and tissue regeneration

Abstract

Injectable multifunctional sponges represent a new generation of biomaterials designed for localized and controlled therapeutic delivery combined with tissue repair properties. Unlike traditional hydro- gels or solid scaffolds, these sponges are injectable, enabling minimally invasive administration. Their pharmacological structure integrates natural and synthetic polymers, bioactive nanoparticles, and therapeutic agents, creating a multifunctional system that responds dynamically to physiological conditions.
