Scientists have created from waste soybean material to restore the skin

Italian scientists have developed an unusual biomaterial from waste tofu and soy drinks that can help heal damaged skin. The development is suitable for 3D printing and can become the basis of new generation medical devices. The study is published in the journal Communications Materials.

The main component of the material was okara, a protein-rich byproduct of processing soybeans. Scientists isolated bioactive peptides from it and found that they have antioxidant and anti-inflammatory properties, as well as stimulate the movement of cells involved in skin repair.

The resulting substance was combined with a biodegradable polymer, creating a mixture for 3D printing. Tests have shown that the material retains useful properties after manufacture of products and is able to gradually release active compounds. Thanks to the technology, it is possible to create medical overlays of various shapes and sizes.

In the future, the development is planned to be used to relieve pain during breastfeeding and recovery after surgery for breast cancer. So far, the effectiveness of the material has been studied in the laboratory. The next stage will be tests on an artificial model of breast skin, which will help assess the possibilities of its medical use.
