New Incredible Biomaterials We are always on the path of inventions and innovations. In addition to building new technologies and machines, the invention of new materials greatly influences the future of products and their use. is a material with a weird name but that will soon be explained when you learn more about it. Wood Sponge is a new material developed by turning wood into a stripped-down version of itself by treating it with chemicals. This material can absorb huge quantities of oil from water. Oil and chemical spillage has been very harmful to bodies of water all around the world, and we have been looking for more efficient ways to combat it. The research team led by Xiaoqing Wang wanted to develop a new absorbent from renewable material, hence wood; the result is a sponge that can absorb 16-46 times its own weight. It can also be reused up to 10 times by squeezing out the absorbed oil. This new sponge surpasses all other sponges and absorbents we use today in terms of capacity, quality, and reusability. is the strongest biomaterial known to man, stronger than steel. Many studies have worked to either replicate this material on a large scale or even surpass spider silk in terms of strength, but they weren’t able to recreate such a material. However, recent research conducted by Daniel Söderberg from the KTH Royal Institute of Technology in Stockholm might have broken the mold. The team of researchers has invented a new material that can be defined as the strongest biomaterial ever produced. The best part of this material is that even though it is artificial, it is biodegradable, which makes it a great alternative to plastic and other non-biodegradable materials. The material is made from cellulose nanofibers that are sourced from wood and plants.
