Peripheral Nerve Regeneration Reimagined: Cutting-Edge Biomaterials and Biotechnological Innovations

Peripheral nerve injuries are frequent clinical issues that can lead to significant functional impairments, greatly impacting patients' quality of life. Developing effective nerve regeneration methods is crucial for restoring function and ensuring the best possible outcomes. This review explores recent advances in nerve regeneration, including nerve guidance conduits (NGCs), which are vital in bridging nerve gaps caused by injury and supporting repair. The field has seen significant progress in biomaterials and biotech, with biodegradable options like collagen and chitosan as well as non-biodegradable materials such as nylon. Innovations like 3D printing have allowed for more intricate conduit designs that more closely mimic natural nerves. Despite these progressions, research continues to focus on improving NGCs-often by adding cells or bioactive substances-to boost nerve regeneration and functional recovery. By analyzing current trends, this review aims to motivate clinicians and researchers to develop more comprehensive nerve repair strategies. It emphasizes approaches that combine scientific innovation with clinical practicality, fostering a more holistic and realistic outlook on enhancing patient outcomes in peripheral nerve regeneration.
