Injection could make body heal itself

23rd April 2007

Nanotechnology could permanently relieve the symptoms of a variety of illnesses including Parkinson's and Alzheimer's disease.

Scientists in the US have begun combining nanotechnology and biology to produce methods by which the body can heal itself. According to the scientists, early results have been amazing.

Paralysed mice with spinal cord injuries have regained the use of their limbs just six weeks after receiving an injection of nanomaterial.

The work is based on the idea that nanofibres can self assemble once injected into the body. In this way they can stimulate the creation of new cells, for example, or activate biological processes.

This applies to Parkinson's and Alzheimer's by preventing the destruction of brain cells.

Dr Stupp, director of the Institute of BioNanotechnology in Medicine at Northwestern University, said: "By injecting molecules…..we have been able to rescue and regrow rapidly damaged neurons.

"The nanofibres, thousands of times thinner than a human hair, are the key to not only preventing the formation of harmful scar tissue which inhibits spinal cord healing, but to stimulating the body into regenerating lost or damaged cells."
