Today, the editor of graphene manufacturers summarized the harm of graphene to the human body on the Internet. Many people want to learn about graphene materials and need to use graphene. When graphene sticks to the skin, you will feel itchy for a while, and then, the skin with graphene will have red spots, which will cause a slight touch when you touch it. Some people ask about the harm of graphene to the human body because of the pain like acupuncture.

What is graphene

Before we understand the harm of graphene to the human body, we need to understand what graphene is?

1. Graphene, Graphene, is a two-dimensional crystal composed of carbon atoms exfoliated from graphite materials. It is the thinnest kind of known materials. In fact, graphene originally exists in nature, but it is difficult to peel off a single-layer structure.

2. Layers of graphene are stacked to form graphite, and graphite with a thickness of 1 mm contains about 3 million layers of graphene. A lightly stroked pencil on the paper may leave traces of several layers or even just one layer of graphene. Nano-material graphene is more stable than previous carbon materials and has a longer service life.

Graphene is potentially harmful to the human body and the environment

A team of biologists, engineers, and materials scientists at a university tested the potential toxicity of this material to human cells. They found that the jagged edges of graphene nanoparticles are very sharp and strong, and can easily penetrate into human skin and the cell membrane of immune cells. It can be seen that graphene does have potential serious harm to humans and other animals.

Many people know that graphene seems to be the gospel that can create miracles in the future for the technology industry, but what you don't know is that this material may not be good for the environment and even our human body. When we talk about graphene, most people are quite excited, such as the thickness of only atoms, this material is very light, strong, flexible, and has good conductivity for heat and electricity. These characteristics make it have the potential to set off a technological revolution, so many people call it a wonderful material.

However, in fact, it has been 10 years since graphene was first isolated in the laboratory. Researchers and the entire industry seem to have no intention to bring it out of the laboratory for large-scale commercial use, and it is said to be used in The cost of research on the potential negative effects of this material is not a lot.

Two recent studies seem to be bad news for graphene. First, a team of biologists, engineers, and materials scientists at Brown University tested the potential toxicity of this material to human cells. They found that the serrated edges of graphene nanoparticles are very sharp and strong, and can easily penetrate into human skin and the cell membrane of immune cells. As shown in the above picture, it can be seen that graphene does have potential serious harm to humans and other animals.

Robert Hurt, one of the authors of this study and a professor of engineering, said: "These materials can be inhaled unintentionally, or deliberately injected and implanted into the human body as components of new biomedical technology, so we need to understand that they are in the body. What kind of interaction will occur with the cell? ”

Another study was initiated by a research team at the University of California. The Bourns College of Engineering found in research that graphene oxide nanoparticles can have an impact on the environment if they find a way to enter the surface or groundwater resources. The team studied groundwater resources that contain very little organic matter. The hardness of these waters is high, and graphene oxide nanoparticles can become unstable and form precipitates in such an environment.

However, in surface waters such as lakes and rivers, where the organic matter content is relatively high and the water hardness is lower, these particles are more stable and can drift to farther places and also flow underground. Therefore, the leakage of such nanoparticles may cause harm to organic matter, plants, fish, animals and humans. The affected area will soon spread. Jacob D. Lanphere, the co-author of the published paper, said: "Today's situation is similar to the situation in which chemicals and drugs flooded our surroundings 30 years ago. We do not yet know what will happen to these engineered nanomaterials when they enter the ground or water. So we need to take the initiative to research, we need data to confirm whether the future technology can apply such materials. ”

What are the damages of graphene to the body

Two recent scientific studies of the latest news do not seem to be very good information for graphene. First, an elite team of microbiologists, technical engineers, and raw material biologists at Brown University tested the potential toxic side effects of such raw materials on tissue cells. They found that the jagged edges of graphene nanoparticles are very sharp and powerful, and they can be punctured into the cytoplasm of people’s skin and their cells. As shown in the picture, it can be seen that graphene is indeed beneficial to people and others. Animals have potentially serious threats.

One of the creators of this scientific research, Robert Hurt, who is also a professor of water conservancy, said: "This kind of raw material can be inadvertently sucked in, or deliberately introduced and embedded in the body as a new type of biomedical technology. Therefore, people must master how they interact in the body and body cells. ”

The other scientific research is conducted by a team of scientific research elites at the University of California. Burns Engineering School

(Bourns College of Engineering) discovered in scientific research that graphene oxide nanoparticles can cause harm to the natural environment if they find a way to enter the soil or surface water resources. The elite team conducted scientific research on surface water resources that contain few organic compounds. This kind of water has high hardness, and graphene oxide nanoparticles can become more and more unstable in such a natural environment.

However, in groundwater such as lakes and rivers, organic compounds have relatively more water content and lower water hardness. This kind of object is more stable and can flow to areas far away from the wave pool, and it will also flow to the ground. Therefore, the leakage of such nanoparticles will always cause serious harm to organic compounds, green plants, fish, small animals and people. The affected area will quickly spread outside. Jacob D. Lanphere, the co-author of the paper, said: "Today's situation is similar to that 30 years ago when chemicals and drugs overflowed people's surroundings. It is still unclear what the nanomaterials of this engineering project will produce when they enter the ground or in the water. Therefore, people must actively conduct scientific research, and people must use statistical data to determine whether such raw materials can be used in future high-tech technologies. ”

What are the hazards of graphene to the body

Today, the application areas of graphene related to the Material Safety Data Sheet are still not detailed. The raw materials in the above book are aimed at the skin and eyes, and they are potentially harmful and irritating for inhalation and ingestion. There is no information temporarily to explain whether these compounds have carcinogen risks or potential growth and development toxic side effects.

Biologists who often talk about the first scientific research above emphasize that the development and design of graphene is still in the initial stage, and as this synthetic raw material, this period is now a good way for people to detect and grasp its potential hazards. opportunity. Before graphene became more and more common in our daily lives, people also spent many years doing in-depth scientific research. Today's challenge is to deal with its safety factor problem, making graphene as safer as possible for people themselves and people's stars.

Summary: I believe that through the introduction of the above article, you have also learned about the harms of graphene to the human body. It can be seen that graphene may contain toxic substances that make people sick. However, most people know that there are several substances in the industry that are not harmful to the human body. They do not understand other toxic compounds, but the "toxicity" in graphene will not harm the human body because they do not understand it. Because of the lack of cognition that gives graphene the possibility of "criminal", health can only be impaired.
