Nanotechnology Applications in Bone Tissue Engineering

The field of bone tissue engineering leverages nanotechnology to create materials and devices that can support, guide and enhance the regeneration of bone tissue. Nanoscale features mimic the natural extracellular matrix, enabling improved cell adhesion, proliferation and differentiation. Nanoparticles can be engineered to deliver growth factors, genetic material or drugs directly to defect sites, thus minimising systemic side effects and improving therapeutic efficiency. Meanwhile, nanostructured scaffolds fabricated by techniques such as electrospinning, 3D bioprinting and layer-by-layer assembly provide controlled porosity, mechanical strength and bioactive cues. Advances in surface functionalisation, including the incorporation of ions or bioactive peptides, further promote osteoinduction and angiogenesis. Despite significant progress in preclinical studies, clinical translation requires addressing challenges related to long-term safety, scalable manufacturing and regulatory approval. The global burden of bone defects—from non-union fractures to degenerative diseases—has driven a multidisciplinary effort to integrate materials science, cell biology and clinical expertise. This convergence has yielded promising platforms that combine tailored nanoscale architecture with targeted bioactivity, heralding a new era of regenerative therapies for orthopaedic and maxillofacial reconstruction.
