we explained how graphene could be used
in biomedical applications to improve
people's lives this is Stan stan is
blind but he hopes to be able to take
part in a clinical study using graphene
devices that could help his eyesight to
go from pitch-black to perceiving shades
and shapes how is this possible
[Music]
graphene has the ability to electrically
stimulates the nervous system of the
brain there it could record the
electrical activity of the nerves and
inject charge into the optical nerve and
produce an image from an external camera
but Stan is not the only patient that
could benefit from graphene's attributes
his best friend Anna has epilepsy Anna
is following recent studies that show
how graphene could be placed into a
delicate sensor able to detect the
specific areas in the brain that are
responsible for the seizures that way
clinicians could understand where
exactly in the brain the episode is
happening and how it can be predicted or
even cured during her research Anna met
Sofia a scientist she explained one of
the key advantages of graphene devices
their multi functionality can both
record and stimulate the electrical
activity of the brain as well as locally
release therapeutic ations on demand
that could offer multiple treatment
options that's also how the doctors hope
to be able to help Sofia with the
effects of Parkinson's disease this new
generation of thin and flexible graphene
based devices could minimize shaking
tremor and other motor symptoms while
the graphene flagship scientists focus
mainly on blindness epilepsy and
Parkinson's disease research in the use
of graphene and 2d materials in medicine
is expanding globally some other
biomedical applications currently under
development include cancer treatment
tissue engineering and drug delivery in
addition graphene's thinness flexibility
and excellent sensing capabilities makes
it suitable for use in wearables
providing Stan Banner and Sofia basic
health checks that they can monitor
themselves and use to inform their
doctors
although research on graphene for
medicine is still at its early stages
tests show promising results that could
offer medical professionals new
multifunctional and more precise
capabilities and help improve the
quality of life for millions of patients
