Scientists engineer a light-sensitive material that can be used to create ingestible medical devices. These devices can then be easily degraded after their function has been performed. Continue reading Scientists engineer ingestible medical devices that can be degraded with light
Skin is the largest organ in human body, and can sense important information such as pressure, temperature and pain. This waterproof barrier protects us from infections and can heal itself. Electronic skins are soft and flexible electronics that mimic the functions of skin in one or multiple aspects, and can give robots or even prosthetic limbs the sensations of real skin. However, unlike real skin, … Continue reading Jellyfish-inspired electronic skin can heal itself under water
Osteoarthritis is a joint disease that occurs when the cartilage (the flexible and slippery tissue that protects the ends of bones in the joints) wears away, causing bones to rub against each other. Common causes of osteoarthritis include aging, sports injuries, and excess body weight. Scientists from Tsinghua University and Shanghai Jiao Tong University have developed nanoparticles that can be injected as lubricant into the … Continue reading Treating knee osteoarthritis with a nanoparticle injection
