Scientists create new technology to treat cancer without using drugs

Scientists tested newly One of the latest new approaches to cancer treatment is very similar to the Trojan horse strategy of making cancer cells self-destruct on their own and without the use of drugs.

This technology is based on the use of very fine nanoparticles coated with an amino acid called L-phenylalanine, which is one of the amino acids on which cancer cells mainly depend and which is not produced by the body but rather by from meat and dairy products.

So far, the technique has been tried in mice, and the nanoparticles have been successful in killing cancer cells effectively.

The amino acid encapsulated in the nanoparticles makes the body “pretend” that it is a cell-friendly amino acid, but when cells use it, it pumps out substances called reactive oxygenates. Reactive oxygen species This quickly causes the cell to self-destruct.

“Contrary to popular belief, in our experience, we have used nanomaterials as medicine instead of using them to transport medicine,” says Dalton Tai, professor of materials science at Nanyang Technological University in Singapore. He also described the mechanism of action of nanoparticles as very similar to the “Trojan Horse” strategy, as the amino acid “acts like a cloak to hide the nanoparticles from within,” he says.

So far, the treatment has been shown to kill around 80% of breast, skin and stomach cancer cells in mice, this percentage is very close to the ability of chemotherapy drugs in use today, but without the side effects of course.
