A researcher at the Universidade Estadual Paulista in São José do Rio Preto has developed an anti-hemorrhagic biofilm with substances found in orange, lemon and apple peels. The invention is promising, as tests demonstrated its potential to contain bleeding in up to one and a half minutes.
Doctoral student in molecular biophysics, Oscar Antonio Niño Santisteban explains that the main raw material of the biofilm is pectin. This is a soluble fiber, found naturally in citrus fruits.
“Pectin is abundant. The food industry uses the pulp and discards the rest. We can use it without harming other production chains. We made a gel with the pectin. The synthesis of our product is cheap to make in the laboratory, in addition to being sustainable”, says Santisteban.
“Previously developed hemostatic agents are inorganic. Ours is an organic product. Chitosan, cellulose and pectin have similar chemical compositions but have different bonds. Pectin has a linkage harnessed to form eggshell structures,” he added.
