A team of biologists, engineers and materials scientists from Brown University tested the material's potential toxicity to human cells. They found that the jagged edges of graphene nanoparticles are very sharp and strong and can easily penetrate the cell membranes of human skin and immune cells. It can be seen that graphene does have potentially serious harm to humans and other animals.
1. What is graphene
1. Graphene is a two-dimensional crystal composed of carbon atoms separated from graphite material. It is the largest known material. A thin kind. In fact, graphene already exists in nature, but it is difficult to peel off a single-layer structure.
2. Graphene is made up of layers of graphene. Graphite 1 mm thick contains about 3 million layers of graphene. When a pencil lightly scratches the paper, the traces left behind may be several layers or even just one layer of graphene. Nanomaterial graphene is more stable and has a longer service life than previous carbon materials.
2. Is graphene used for heating?
Graphene heating infrared radiation uses scientific technology to deliver natural warmth. The generated far-infrared rays have strong penetrating and radiating power, and have significant temperature control and vibration effects. They are easily absorbed by objects and converted into the internal energy of the objects.
