Nano-scientists' efforts lead to curing nerve injuries

TEHRAN, Aug. 13(MNA) – Iranian nanotechnology researchers from Sharif University of Technology have produced a laboratorial sample of nerve conduction channel that can be used in treating nerve injuries.

According to Iran Nanotechnology Initiative Council, biodegradable and biocompatible polymers and graphene were used in the production of the channel. The channel can be used in the treatment of nerve injuries after passing the complementary tests and obtaining the desirable results.

Neural system is divided into two local and central parts. Neuron is the main cell in the neural system. Neurons are not able to proliferate but they can recover themselves. This recovery is much more significant in the local neural system. Many people suffer from local neural system injuries every year, and there are different methods to recover the injuries.

The aim of the research which was conducted by Iranian researchers from Sharif University was to design an optimum nerve conduction channel to carry out crack treatment process successfully inside the local neural system. The optimization process focused mostly on the appropriate combination to produce nerve channel.

The conductive composite of polyaniline/graphene (PAG) was synthesized to produce the nerve conduction channel, and it was used in the production of the final conductive scaffolds (PAG/gelatin/chitosan).

This research also studies various bioengineering properties of nerve conduction channels, including mechanical properties, conductivity, porosity, morphology and structure, toxicity and compatibility with human body. It was approved that the product is suitable for the recovery of local neural system injuries. The positive effect of electrical impulse was also approved by carrying out experiments.

Results of the research have been published in International Journal of Biological Macromolecules, vol. 74, issue 1, 2015, pp. 360-366.
