How do carbon nanomaterials work in treating breast cancer?

Breast cancer is a serious disease that affects millions of people around the world. Traditional treatment methods such as surgery, radiation therapy, and chemotherapy can often cause severe side effects and may not be effective in all cases. As a result, researchers are constantly searching for new and improved treatment options.

One promising area of research involves the use of carbon nanomaterials in the treatment of breast cancer. Carbon nanomaterials, including carbon nanotubes and graphene, possess unique properties that make them ideal for targeting and destroying cancer cells.

The first step in utilizing carbon nanomaterials for breast cancer treatment is to functionalize them. Functionalization involves modifying the surface properties of the nanomaterials to ensure they can specifically target cancer cells. This can be achieved by attaching targeting molecules, such as antibodies or peptides, to the surface of the nanomaterials. These targeting molecules can recognize and bind to specific receptors or proteins that are overexpressed on cancer cells.

Once the nanomaterials have been functionalized, they can be administered to the patient. This can be done through various routes, including intravenous injection or localized delivery.
