Injuries to peripheral Nerves may causes chronic pain , paralysis or major disabilities . All these may be the reason for not achieving your goal of the life .
But Scientists discovered a stretchable Conductive hydrogel . It could be used in the future for repairing these damaged nerves . They report their results in ACS nano .
Purpose For Discovering Hydrogel
Severe nerves damage or major cut in the nerve may be difficult to repair which can occur during accident . Now a days doctors use autologous method for nerves repair in which they cut a part of nerve from somewhere else in the body itself and attach it onto damaged nerve endings .
But for this reason, multiple follow up surgeries may be required which can be difficult for a person to afford .
Doctors also use artificial nerve Graft along with supporting cells which could be a life saving support but it takes a lots of time to get functional .
What is Hydrogel ?
Qun-Dong Shen, Chang-Chun Wang, Ze-Zhang Zhu and colleagues wanted to develop an effective, fast-acting treatment that could replace autologous nerve transplantation.
For this Purpose, they made a water swollen, bio compatible conductive hydrogel which could do this work efficiently .
This is tough but a stretchable polymer containing polyacrylamide and polyaniline . This is 3D microporous in which damaged nerve cells enter easily and could help to repair damaged tissue .
Experiment On Rat
First time , Chinese researcher performed this experiment on the damaged nerve part of frog . They attached hydrogel on the Damaged sciatic nerve of the frog And waited for 2 weeks only.
They find that a performance of the frog is much better than non treated frog . Conductance of the hydrogel can improve with irradiation of near infra-red light . It can easily enter into its microporous part and improve its conductance .
