The BIOMAT research group\u2019s work focuses, among other things, on the design of materials based on proteins and polysaccharides (cellulose, agar, etc.) using sustainable products and processes, and on the study of their mechanical properties. In this case, the team carried out an exhaustive study of the mechanical properties, biocompatibility and toxicity of the aforementioned 3D-printed scaffolds.\u00a0<\/p>\n
Tensile and compression tests indicate that \u201cthe structure has shape memory; in other words, when a particular force is no longer applied, the material returns to its original shape\u201d, they said. This feature is crucial because \u201ccartilage is also subjected to compression or tensile forces that cause it to deform, but it then recovers its original shape when these forces are removed\u201d, added Osquila.\u00a0<\/p>\n
The team saw that \u201ccellulose reinforces the structure and provides rigidity and tensile strength. The more cellulose the structure contains, the greater the strength\u201d. Soy protein, meanwhile, \u201cgives the ink body so it can be printed, and gelatin serves as nourishment for the cells\u201d, added Guerrero. The effective interactions among all the ink\u2019s components offer properties that improve the mechanical performance and biocompatibility of the scaffolds. \u201cWe managed to dissolve the cellulose inside the ink, and in doing so we obtained the properties we needed to be able to print the structures with precision and promote cell growth and tissue regeneration,\u201d he confirmed.\u00a0<\/p>\n
Guerrero also emphasised that the raw material for this bio-ink is of natural origin: \u201cWe\u2019re talking about proteins and cellulose originating from food industry waste. Our work demonstrates that by using natural materials we are also able to achieve excellent solutions: highly consistent materials that serve as reinforcement and possess excellent mechanical properties.\u201d The team\u2019s aim is to develop materials that mimic natural ones. \u201cBy means of minor natural modifications, we obtained biocompatible materials that do not harm the body, thus helping us move towards achieving more sustainable and personalised medicine,\u201d he stressed. In this respect, the BIOMAT group develops and studies a range of materials in the laboratory.\u00a0<\/p>\n
