Aerogels formed from cellulose are nothing new, but nobody had ever tried making it with a cellulose sourced from denim before. The team found that in doing so, it produced an aerogel with a unique porous structure, featuring vertical nanoscopic tunnels throughout. The team believes the sticky nature of the denim-based cellulose is why these tunnels form, but whatever the reason, the material they are left with is perfectly formed for use as artificial cartilage.
