What kind of material is graphene? Is it harmful to the human body?

There is currently no evidence that graphene is harmful to the human body. Its low toxicity, inert surface, good biodegradability and inability to be absorbed by cells make it biocompatible. These properties make it widely used in various fields such as electronic devices, energy storage, and biomedicine.

Graphene: a harmless nanomaterial

Graphene is a type of material composed of carbon atoms Single layer atomic crystal. It has attracted much attention due to its excellent electrical, mechanical and thermal properties.

Is graphene harmful to the human body?

There is currently no evidence that graphene is harmful to the human body. Conversely, studies have shown that graphene is biocompatible, meaning it does not have harmful effects on living tissues or cells.

Why is graphene harmless to the human body?

• Low toxicity: The chemical inertness of graphene makes it less toxic and will not release harmful substances after contact with the human body.
• Inert surface: The surface of graphene is not chemically active and will not interact with biomolecules in the human body.
• Good biodegradability: Graphene can be degraded by certain enzymes, which makes it easy to remove in the body.
• Cell-free absorption: Graphene sheets are too large to be absorbed by cells, further reducing their toxicity risk.

Applications of Graphene

Due to its harmlessness and unique properties, graphene has found a wide range of applications in various fields, including:

• Electronic devices: High conductivity and low resistance make it an ideal material for electronic devices.
• Energy Storage: Its high surface area and high electrical conductivity make it a promising material for supercapacitors and batteries.
• Biomedicine: Its biocompatibility and versatility give it potential in tissue engineering, drug delivery, and biosensing.
• Other applications: Graphene is also used in other applications such as composites, coatings, sensors and catalysts.
