🔬 Revolutionary Breakthrough: 3D Printing Inside the Body Without Surgery!

 

A team at Caltech has developed ultrasound-guided 3D printing—a game-changing technique that could fabricate medical implants inside the body and deliver personalized therapies to deep tissues—all without invasive surgery!

💡 How It Works:
The DISP (Deep Tissue In Vivo Sound Printing) platform uses:
✔ Low-temperature–sensitive liposomes (LTSLs) to carry cross-linking agents
✔ Focused ultrasound to trigger precise, controlled biomaterial formation
✔ Real-time imaging for accuracy

🐭 Proof of Concept:
✅ Printed drug-loaded biomaterials in mouse bladders
✅ Engineered functional tissues deep in rabbit muscles
✅ No tissue damage—unpolymerized ink cleared safely in a week

🌟 Why It Matters:
➡️ Enables minimally invasive treatments
➡️ Customizable for drug delivery, tissue repair & bioelectronics
➡️ Overcomes limits of traditional light-based bioprinting

🚀 Future Potential:
"DISP unlocks applications in bioelectronics, regenerative medicine & targeted therapy—all inside the living body!" — Wei Gao, PhD, Senior Author
