A team of engineers at Georgetown University is developing an alternative to traditional metal implants and bone grafts. Their proposal involves grafts made from pectin, a natural compound extracted from fruits like apples and citrus. This approach aims to solve problems with current methods, such as infections, chronic pain, or poor integration with the patient's bone. The goal is to improve natural bone regeneration.
Bioinspired architecture: pectin and hydroxyapatite 🦴
The innovation lies in the implant's structure. A pectin core, a biocompatible hydrogel that can house living cells and whose porosity facilitates nutrient flow, is printed at room temperature. This core is encapsulated between two layers of hydroxyapatite, the mineral that gives rigidity to natural bone, providing the necessary mechanical strength. This combination replicates the architecture of native bone tissue for more effective integration.
From the shopping cart straight to your femur 🍎
It's curious to think that a key component for repairing a broken bone could come from the same jam you spread on your breakfast. Science is advancing so that, in the future, you might be told that the support for your jaw comes from an apple, not from a metalworking shop. An unexpected twist where the local fruit shop could unknowingly become a supplier of high-tech medical material.
