Scientists have developed a new method for printing organs inside the body using ultrasound waves. Teams from Duke University in the United States and Harvard Medical School have created a biocompatible ink that hardens under the influence of ultrasound waves. The method is called “deep-penetrating acoustic volumetric printing” (DVAP) and is based on the sono-thermal phenomenon. According to researchers, ultrasound waves have the ability to penetrate deeper than light, enabling precise deposition of ink inside the human body.
The ink, called sono-ink, is composed of hydrogel, microparticles, and chemical molecules that react to ultrasound waves. By controlling them, various shapes can be formed, such as scaffolding resembling bone or hydrogel balloons. Successful tests have been conducted in the laboratory on a damaged goat heart and a chicken bone, demonstrating the potential of this new technology.
The 3D printing method using ultrasound waves has many potential applications in surgery and therapy. It can be used in repairing various structures in the body, such as bones or heart valves. Additionally, the ink can be used to deliver drugs directly to targeted areas.
Although further research is needed before this technology can be introduced to clinics, scientists are very excited about its possibilities. The 3D printing method using ultrasound waves opens up a fascinating new path for medicine. Researchers eagerly look forward to exploring the full potential of this tool.
FAQ:
– What is DVAP? DVAP stands for deep-penetrating acoustic volumetric printing, a technique using penetrating acoustic waves.
– How does the 3D printing method using ultrasound waves work? The method is based on the sono-thermal phenomenon, where acoustic waves cause an increase in temperature in the material.
