'Ultra-small submarine' carries drugs that kill cancer cells

The new system acts as a micro-submarine, capable of passing through the cell wall of the cancer and releasing itself.

Researchers at Radboud University in the Netherlands, in a study published in the journal Angewandte Chemie, have developed a system that can detect cancer cells, release drugs to kill harmful cells, according to the study. Seeker.

Cancer cells can be destroyed by new drug transmission techniques.(Artwork: Seeker).

Scientists use micro-sized bags synthesized in the laboratory. Taken into the body from the vicinity of the cancer cell, the drug bag reacts with some chemicals to reach the pathogen.

This system acts as a miniature submarine , self-propelled by a chemical engine using fuel as weak hydrogen hydrogen peroxide . When hydrogen peroxide dissolves, the drug bag moves forward, penetrates the cancer cell wall and decomposes itself to release the drug.

The mechanism of self-release of drugs without external effects takes place when glutathione, a chemical agent often found with high density in cancer cells, reacts with a substance that holds the drug inside the bag, breaks down Covalent bonds are disulfide S – S bridges, which help the drug to be released.

The new technique could help doctors improve the method of delivering the drug to exactly the desired location in the patient's body in the future.
