Tissue Engineering of Nanocomposite Scaffolds
Summary
Tissue engineering of nanocomposite scaffolds integrates materials science, biology and engineering to create three-dimensional frameworks that support cell attachment, proliferation and differentiation for tissue repair and regeneration. By combining biocompatible polymers with inorganic nanoparticles or bioactive ceramics, these scaffolds replicate the mechanical strength and biochemical cues of native extracellular matrices. Advanced fabrication techniques—such as three-dimensional printing, freeze-drying and electrospinning—permit precise control over architecture, porosity and surface chemistry, tailoring constructs for specific tissues from bone to cartilage. Nanocomposite formulations enhance osteoconductivity, vascularisation and antimicrobial properties while maintaining degradability compatible with tissue remodelling. As a result, they promise to reduce dependence on donor grafts and improve outcomes in orthopaedics, maxillofacial surgery and beyond. Ongoing efforts focus on optimising scaffold composition, analysing cell–material interactions and scaling production under regulatory standards to translate laboratory innovations into clinical therapies worldwide.
