Golden nanoparticles cure cancer

British scientists have developed smart nanomaterials that can kill cancer cells without affecting other parts of the body.

The cancer cell's DNA always contains the gene that regulates neuralgogenesis (a new blood vessel born on the tumor) to ensure adequate nutrition. The process of inhibiting and destroying these genes will prevent neural-producing tumors from controlling the metastasis and killing cancer cells. This is the new trend of medical researchers around the world to find effective therapies for the disease that is considered to be very difficult.

The research team from the University of Southampton , led by physicist Antonios Kanaras points out that a small amount of gold nanoparticles can be activated or inhibited that selects genes that govern the formation of blood vessels on tumors. . Thereby controlling the supply of oxygen and nutrients to most cancer cells.

The use of gold nanoparticles will only selectively affect cancer cells. Other normal cells in the same tissue will not be affected.

The team took a further step in controlling the extent of destruction of the endothelial membrane (the inner cell layer of blood vessels) using laser beams. These endothelial cells line the inside of all blood vessels and play a key role in the formation of new blood vessels.

Health quoted Dr. Kanaras as saying: ' We have discovered the dual feature of gold nanoparticles in controlling cellular metabolism .

" By combining laser irradiation, we can destroy the endothelial cells thereby cutting off the supply of blood to the tumor. In addition, these molecules also affect the metabolism through Cell membranes help increase the body's ability to absorb drugs , "he said.

This research has contributed significantly to opening a new trend in nano-surgical technology that is being developed. However, the immediate goal of the scientists is to focus on perfecting the technology of manufacturing nanoparticles to control the process of neural formation to contribute to the fight against cancer.
