About this Research Topic
Lasers are an invaluable tool for biomaterials processing at different length scales. They can be used to alter different properties of materials, surface engineer complex materials, or to produce new materials. In this sense, laser processing of biomaterials accomplishes the application of laser-based techniques for the modification, fabrication, or synthesis of medically-relevant materials. Therefore, lasers can create medical devices that exhibit unique biological characteristics, and patient‐specific attributes.
Laser processing of biomaterials has several advantages over other methods, namely low surface contamination, low mechanical damage, and high controllability to process geometrically intricate three-dimensional components. These advantages combined with the multiple possibilities offered by the lasers has stimulated the research in this field. Two main topics are found in this field, the modification of the surface (with different textures, patterns, and coatings), and the fabrication of three-dimensional parts made from a variety of biomaterials.
Lasers have been used to modify the surface structure of different materials (metals, polymers, or ceramics) at the micro- and nanoscale; however, more research is necessary to properly tailor the surface of a biomaterial to elicit a proper cell response. On the other hand, the research in the fabrication of scaffolds from a variety of biomaterials using 3D printing techniques based on laser is currently intense. This technology has demonstrated the feasibility to produce medically-relevant parts; however, fabricated parts are generally made from one biomaterial. The combination of different biomaterials, and a better understanding of the interactions of these parts with the living tissues arise as some major points to elucidate.
The main aim of this Research Topic is to publish high quality original research and review articles addressing the recent advances on laser processing of biomaterials. This will stimulate and develop a better understanding of the state of the art in the field of laser processing of biomaterials, and on the challenges to be addressed over the coming years.
Potential topics include, but are not limited to:
• Laser texturing and patterning of biomaterials
• Laser deposition of bioactive thin films and coatings
• Rapid prototyping of biomaterials assisted by laser
• Laser transfer of biomaterials
• Laser machining of biomaterials
• Laser micro- and nanofabrication of biomaterials
• Biological evaluation and performance of laser processed biomaterials
