Absolutely, and it has been applied to cancer.
**。Graphene is made up of a single layer of carbon atoms.
A two-dimensional material linked by sp2, graphene does not contain any heavy metal elements because it is composed of carbon atoms.
Therefore, graphene has better biocompatibility and lower toxicity. At present, graphene research and application mainly focus on sensors, solar cells, seawater desalination, hydrogen storage material preparation, and aerospace.
and other fields. Of course, graphene (graphene oxide is generally used.
In the field of biomedicine, some good results have also been achieved. In particular, there have been many reports on the use of graphene oxide for antimicrobial research. Of course, the use of graphene for cancer** has also become a hot area.
1.Graphene oxide converts near-infrared light into heat, which heats cancer alive (photothermal**).
Graphene has a certain absorption of near-infrared light, which can convert the absorbed light into heat, which will promote the local heating of tumor tissue, resulting in the death of tumor heat. This is known as photothermal**.
2.Graphene oxide is used as a drug carrier to achieve high-efficiency chemotherapy for tumors.
Conventional chemotherapy drugs are often not very water-soluble, and there is no targeting, which will inadvertently injure normal cells, and long-term use will also make cancer cells develop drug resistance.
Graphene oxide has both a hydrophilic group and a hydrophobic sp2 carbon framework, so it is amphiphilic. Using the accumulation effect, anti-cancer drugs can be loaded to form nanoparticles, and then through the passive EPR effect (tumor tissue enrichment effect), the drug can be mainly enriched in tumor tissue, thereby reducing toxicity. In addition, if graphene oxide is actively targeted to the molecule in modification, the specific cancer cell killing ability of active and passive targeting can be realized.
Of course, it can also be combined with the photothermal effect of graphene oxide to achieve the synergy of photothermal and drug chemotherapy for tumors, thereby greatly improving the efficiency. In addition, graphene oxide can also be modified to carry nucleic acids to achieve genes**.
and chemotherapy**.

Non-carcinogenic. The chemical properties of graphene.
Similar to graphite, graphene can adsorb and desorb a variety of atoms and molecules. When these atoms or molecules act as donors or acceptors, graphene carriers can be altered.
and graphene itself can maintain very good electrical conductivity.
But when adsorbent to other substances, such as H+ and OH-, some derivatives are produced that make the conductivity of graphene worse, but no new compounds are produced. Therefore, the properties of graphene can be inferred using stone silver nanomo.
Redox method:
The redox method is through the use of sulfuric acid, nitric acid.
and other chemical reagents and potassium permanganate.
Oxidants such as oxygen water oxidize natural graphite, increase the spacing between graphite layers, and insert oxides between graphite layers to obtain graphite oxide.
Then the reactants were washed with water, and the washed solids were dried at low temperature to obtain graphite oxide powder. Graphene oxide was prepared by stripping the graphite oxide powder by physical peeling and high-temperature expansion.
Finally, graphene oxide is reduced by chemical method to obtain graphene.
This method is simple to operate and has a high yield, but the quality of the product is low. The redox method uses strong acids such as sulfuric acid and nitric acid, which is more dangerous, and must use a large amount of water for cleaning, which brings greater environmental pollution.

Summary. Pro, graphene does not cause cancer.
Pro, graphene does not cause cancer.
There are no experiments to show whether there is a carcinogenic risk or a potential danger. However, graphene is potentially harmful to both the human body and the environment.
Engineers and a team of materials scientists have examined graphene's potential toxicity to human cells. They found that the serrated edges of graphene nanoparticles are very sharp and strong, and can easily penetrate the cell membranes of human ** and immune cells, which shows that graphene is indeed potentially harmful to humans and other animals.
Graphene oxide nanoparticles can have an impact on the environment if they find a way to enter the surface or groundwater, and the groundwater resources that the team studied contain very little organic matter, these water hardness is high, and graphene oxide nanoparticles will become unstable in such an environment and form precipitate disorders.
