How to design Printable Adhesives for Tissues and Bones

Scientists and engineers have long been inspired by nature’s designs to create innovative solutions. One such example is the development of printable adhesives for tissues and bones, inspired by the remarkable adhesive properties of mussels.

Mussels are known for their ability to firmly attach themselves to various surfaces, even in the harsh and dynamic marine environment. This is made possible by a unique adhesive protein called mussel adhesive protein, or MAP. MAP contains amino acid residues that allow it to bind to both organic and inorganic surfaces.

Researchers have successfully replicated the adhesive properties of mussels by creating synthetic versions of MAP. These synthetic adhesives can be printed onto tissues and bones, providing a strong and biocompatible bond. The ability to print these adhesives allows for precise application and customization, making them suitable for a wide range of medical applications.

One potential application of printable adhesives is in tissue engineering. Tissue engineering aims to create functional tissues and organs in the lab for transplantation. By using printable adhesives, researchers can enhance the integration of engineered tissues with the surrounding native tissues, improving the success rate of transplants.

Another promising application is in orthopedic surgery. Printable adhesives can be used to secure implants, such as artificial joints or bone plates, to the surrounding bone. This improves the stability of the implant and reduces the risk of complications, such as loosening or infection.

Furthermore, printable adhesives can also be used in wound healing. They can be applied to close and seal wounds, promoting faster healing and reducing the risk of infection. The customizable nature of these adhesives allows for tailored solutions, accommodating different wound sizes and shapes.

While the development of printable adhesives inspired by mussels is still in its early stages, the potential benefits are promising. These adhesives have the potential to revolutionize various medical fields, improving patient outcomes and quality of life.

As researchers continue to refine and optimize these adhesives, we can expect to see more applications and advancements in the near future. The natural world continues to inspire and provide valuable insights for scientific and technological innovation.
