Innovative Nanoparticle Soldering Advances Wound Healing
Not every wound can be closed with needle and thread. Empa researchers have now developed a soldering process with nanoparticles that gently fuses tissue. The soldering technique is expected to prevent wound healing disorders and life-threatening complications from leaking sutures. The team recently published the promising method in the journal Small Methods and applied for a patent.

Suturing wounds with needle and thread has been a surgical principle for over 5,000 years, but it can lead to additional injury and life-threatening problems. The researchers used lasers to solder wounds, overcoming the challenges of temperature control in biological materials.
They developed a bonding agent with metallic and ceramic nanoparticles and used nanothermometry to control temperature. The combination of nanoparticles in the bonding paste allows for precise temperature regulation in real time, making it suitable for minimally invasive surgeries.
The researchers achieved successful bonding of wounds on organs and challenging tissue samples in laboratory tests and have filed a patent application for the nanoparticle composite material. They have also replaced the laser light source with gentler infrared light, bringing the technology closer to being used in hospitals..
