Researchers have developed a minimally-invasive and precise brain drug delivery system that is controlled by an external magnetic field. Read Anqi Zhang’s article to learn more about neuron modulation by drug delivery! Continue reading Magnetic field-controlled drug delivery to the brain
Colonies of social insects are capable of self-organizing and accomplishing complex tasks through individual interactions. For example, to march across large gaps, ants grip the bodies of each other, forming a living bridge that allows the colonies to reach the other side. Inspired by this swarm behavior of ants, scientists from the Chinese University of Hong Kong developed a nanoparticle self-assembly system that can fix … Continue reading ‘Ant bridge’-inspired nanoparticle assembly fixes broken electrical circuits
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
