Plasma-Enhanced Tissue Engineering: Exploring Plasma-Assisted Fabrication of Scaffolds for Regenerative Medicine

Abstract Plasma-enhanced tissue engineering is a rapidly advancing field that leverages the unique properties of plasmas to improve the fabrication and functionality of scaffolds used in regenerative medicine. Plasma technology, through surface modification, polymerization, and functionalization, offers significant advantages in creating scaffolds that are biocompatible, bioactive, and conducive to cell attachment, proliferation, and differentiation. This paper explores the potential of plasma-assisted techniques in the fabrication of scaffolds for tissue engineering, emphasizing the role of plasma in enhancing scaffold properties such as surface roughness, hydrophilicity, and mechanical strength. By utilizing various plasma sources, such as dielectric barrier discharge (DBD) and radiofrequency (RF) plasmas, scaffold materials ranging from synthetic polymers to bioceramics can be modified to facilitate tissue regeneration. The incorporation of bioactive molecules and growth factors through plasma treatment further promotes cellular interactions and tissue integration. Additionally, plasma-enhanced scaffolds are explored in the context of bone, cartilage, skin, and nerve regeneration, highlighting their applications in diverse regenerative therapies. Despite significant progress, challenges remain in scaling plasma technologies for clinical use. Future research in optimizing plasma parameters and integrating plasma techniques with 3D printing holds promise for overcoming these barriers and advancing regenerative medicine.
