The biomedical applications of graphene and its composite include its use in gene and small molecular drug delivery. It is further used for biofunctionalization of protein, in anticancer therapy, as an antimicrobial agent for bone and teeth implantation.Jun 7, 2018
How can graphene be used in medicine?
Why is graphene used in medicine?
Graphene's unique properties allow for ground-breaking biomedical applications. Targeted drug delivery; improved brain penetration; DIY health-testing kits and 'smart' implants.
How is graphene used in drug delivery?
The high level of chemical reactivity vested in the planar structure of graphene can be used to load various drugs and biomolecules with maximum radical scavenging effect. The integration of graphene and polymers brings electrical conductivity to scaffolds, making them ideal for cardiac or neuronal tissue engineering.
How is graphene oxide used in medicine?
Graphene oxide (GO), an oxidized derivative of graphene, is currently used in biotechnology and medicine for cancer treatment, drug delivery, and cellular imaging. Also, GO is characterized by various physicochemical properties, including nanoscale size, high surface area, and electrical charge.

What is the use of graphene in nanotechnology?
There are four areas that graphene nanotechnology can find application in renewable energy. These areas are (1) hydrogen fuel cells, (2) solar (photovoltaic) cells, (3) battery-powered vehicles, and (4) energy storage devices and other applications [16].
What medicines have graphene oxide?
Some researchers indicated that graphene oxide can be used as a nanocarrier for loading and delivery19,20,21 of commonly used anticancer drugs such as SN-3822, doxorubicin, camptothecin, and methotrexate23,24.
What is graphene hydroxide used for?
Thus, the material investigated here can be used not only for energy storage systems demanding high volumetric capacitance but also accelerate the development of new electric double-layer capacitor (EDLC) materials for supercapacitors with high volumetric capacitance.
Is graphene better than lithium?
Graphene offers higher electrical conductivity than lithium-ion batteries. This allows for faster-charging cells that are able to deliver very high currents as well. … Lithium-ion stores up to 180Wh of energy per kilogram while graphene can store up to 1,000Wh per kilogram. Finally, graphene is safer.
