Miniaturized ultrasonic device capable of capturing and moving single cells and tiny living creatures.
University of Glasgow researchers have devised a Heptagon Acoustic Tweezer which makes use of resonance for manipulating matter. This sonic tweezer uses acoustic force to build cell matrices with the possibility of repairing injured nerves.
The discovery could lead to developing a drug that can trigger regrowth of damaged nerves.
Spinal cord injuries are currently irreparable. Most people who suffer from such an injury never fully recover, and many end up with partial or even full paralysis. Although we’ve made great strides in understanding how spinal injuries damage nerves and how we might fix the spinal cord in the future, and even how those patients can cope in the meantime, we still don’t know how to repair the nerves themselves when such an injury occurs. However, scientists at Imperial College London have recently discovered a mechanism that allows them to repair, and even regenerate, nerves in the central nervous system after a spinal cord injury.
