Scientists from the Institute of Materials Research of the UNAM created a patch to prevent amputations caused by ulcers in diabetic patients, which reach about 100,000 in Mexico annually.
The piece is made with polymeric nanoparticles that encapsulate a bioactive, which favors the regeneration of skin in such patients, according to María Concepción Peña Juárez, postdoctoral researcher of the body.
In an interview, Peña Juárez explained that when the material comes into contact with the damaged tissue, it immediately begins to degrade and release the bioactive (based on natural products) to regenerate the skin.
In the Science and Humanities Fair at the National Autonomous University of Mexico (UNAM), Peña Juárez specified that the nanoparticles come from various materials and are smaller than the diameter of a pin.
The patch is made from a synthetic polymer —from a molecule, smaller ones are formed called monomers— compatible with biological systems that do not generate any rejection.
According to Peña Juárez, with the placement of that their patch, the healing progress of a diabetic foot ulcer is observed between 14 and 21 days.
She said that the Institute for Materials Research, which is directed by Israel Betancourt, has supported the preparation of this material and its tests.
“I am on a postdoctoral stay with Dr. Ricardo Vera Graciano, responsible for the Nanofiber Laboratory for Tissue Engineering. I arrived with him precisely to develop this technology and I also had the support for this project from the UNAM authorities.”
The Mexican Diabetes Association (AMD) reported that one in 20 Mexicans living with diabetes mellitus has one foot amputated at some point in the development of the condition, due to lack of control of glucose levels.
Only half of people who feel alterations in the sensation of the feet are treated, while the other 50% remain without professional care and when they arrive it is too late to save the limb.
