The Role Of Graphene In The Biological Field

wallpapers Tech 2020-12-24
Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp² hybrid orbitals.
 
Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered a revolutionary material in the future.
 
Biological
 
Graphene is used to accelerate the osteogenic differentiation of human bone marrow mesenchymal stem cells, and it is also used to make biosensors of epitaxial graphene on silicon carbide. At the same time, graphene can be used as a nerve interface electrode without changing or destroying properties such as signal strength or scar tissue formation. Due to its flexibility, biocompatibility and conductivity, graphene electrodes are much more stable in vivo than tungsten or silicon electrodes. Graphene oxide is very effective in inhibiting the growth of Escherichia coli without harming human cells.

 
Prospects
 
The research and application development of graphene continues to heat up. Graphene-related materials are widely used in battery electrode materials, semiconductor devices, transparent displays, sensors, capacitors, transistors, etc. In view of the excellent properties of graphene materials and their potential application value, a series of important progress has been made in many disciplines such as chemistry, materials, physics, biology, environment, and energy. Researchers are committed to trying different methods in different fields to prepare high-quality, large-area graphene materials. And by continuously optimizing and improving the graphene preparation process, reducing the cost of graphene preparation so that its excellent material properties can be used more widely and gradually moving toward industrialization.
