Functional Applications of Nanomaterials in Plastic Surgery: Strategies, Practice and Evaluation

Nanomaterials offer promising applications in plastic surgery due to their unique properties, with significant advancements in skin anti-aging, maxillofacial repair, and hair regeneration. This study highlights that nanomaterials, through size control and pH-sensitive design, can effectively deliver drugs and adapt to environmental changes, achieving a 95% wrinkle filling rate and a 41% increase in hair density. However, challenges such as the accumulation of metal nanoparticles causing oxidative damage and the photodegradation of silver nanoparticles pose safety concerns. Additionally, high energy consumption and costs hinder industrialization. The study underscores the importance of long-term safety monitoring and overcoming industrial production challenges for sustainable development.
