The on-going development of LED research and bioelectronics medicine has sparked off a new solution for curing bladder problems. A team consisting of researchers from Washington University School of Medicine, the University of Illinois and Northwestern University has created an implantable device with biointegrated LEDs that can detect and tamp overactivity in the bladder.
The research team of neuroscientists and engineers introduced a miniaturized bio-optoelectronic device that is soft and stretchy and implanted it around the bladder of the lab rats. The device expands and contracts as the bladder fills and empties. The researchers also inject proteins called opsins into the animals’ bladders. The opsins are carried by a virus that binds to nerve cells in the bladder, making those cells sensitive to light signals. Then the researchers are able to use optogenetics — the use of light to control cell behavior in living tissue — to activate those cells.
