Laser-treated Graphene circuits drive stem cells

Schwann cells are vital objectives for therapy of stem cell since they cover neural axons and can assist re-grow diseased or damaged nerves, probably bringing back progress to immobilized legs and arms. Separating these cells has been tricky, but scientists at Iowa State University may have come upon on a method that will permit for bunch manufacture of Schwann cells.

The scientists earlier designed a method of employing lasers to produce textured and patterns on Graphene, a two-dimensional substance composed up of carbon atoms. What they found is that they can utilize this method to stimulate bone marrow stromal stem cells, which can be yielded from the same patient that is being taken care of, to separate Schwann cells much rapidly than ever.

An important constituent in the procedure is a Graphene inkjet printing method created by ISU. Conversely, as soon as Graphene electronic circuits were out, they had to be processed to enhance electrical conductivity that normally indicates chemicals or elevated temperatures. Both of them could harm surfaces of flexible printing along with paper or plastic films. This issue was resolved by designing laser technology controlled by a computer that specifically irradiates inkjet-printed Graphene oxide. The treatment gets rid of ink binders and lowers Graphene oxide to Graphene, actually bonding together millions of small Graphene crumbles. The procedure makes electrical conductivity more enhanced than before by 1000 times.

The team developed electronic circuits from Graphene employing an inkjet printing method and used their laser treatment on the exterior part of the Graphene. Keeping the stem cells onto this exterior part and running almost 100 MiliVolts of current via the cells for almost ten minutes every day for a time span of fifteen days separated up to 85% of Schwann cells from the normal stem cells. This is both more efficient and faster than the earlier most excellent process of the chemical.

For now, the technology has not been made commercial and various tests are required to be conducted. Researchers also say that this will be a beginning of new era in the medical industry as they claim that this technique will be dissolvable in nature as well.
