Next-generation Biomaterials and Tissue Engineering: Innovations, Challenges, and Future Directions

Abstract

Biomaterials and tissue engineering have undergone significant advances, particularly with the integration of nanoscience technology. Recent progress in nanostructured scaffolds and nanoparticle-based delivery systems has provided novel opportunities for tissue regeneration. However, the key challenges remain and must be addressed. These include the optimization of the long-term stability of nanoengineered constructs and addressing the concerns regarding nanotoxicity. Fine-tuned mechanical properties enable the adoption of vehicle-based targeted approaches to drug and gene delivery. However, much remains to be learned regarding the interactions between nanomaterials and tissues. Comprehensive safety assessments and standardized toxicity evaluations are essential for clinical translation. These emerging technologies combine the three-dimensional bioprinting of induced pluripotent stem cells with nanomaterials and new pathways for personalized medicine. Nanoengineered smart materials and biosensors have the potential to enable real-time monitoring of engineered tissues, which can pave the way for unparalleled advances in personalized therapies, particularly for chronic diseases. The bioactivity of nanomaterials offers new avenues for tissue regeneration. This review explores the status, successes, challenges, and future directions of biomaterials and tissue engineering, with a specific focus on nanoscience applications. Key areas for future research include nano-bio-interfaces, in situ tissue remodeling, and biofabrication techniques. These insights can guide researchers to navigate the rapidly evolving landscape of nanoscience, related biomaterials, and tissue engineering. The integration of nanomaterials into tissue engineering is an emerging and advanced field that has significant implications for regenerative medicine. 2026, Bentham Science Publishers. © 2026 The Author(s).
