US Scientists Develop "Nano-drug" 50,000 Times Smaller Than Ant to Kill Cancer Cells

A US team of scientists has developed a "nano-drug" that is 50,000 times smaller than an ant. The newly developed drug delivers chemotherapy directly to tumors, as nanoparticles invisible to the human eye are used to transport chemical drugs, according to the British newspaper "Daily Mail".

The newspaper said that nano-carriers use microscopic particles that are invisible to the human eye, to provide new immunotherapy and existing chemical drugs, and researchers from the University of Pittsburgh, USA, hope that the treatment will reduce some of the side effects associated with traditional cancer treatments, as the new treatment works by stopping the production of an immune protein. It is inhibited in cancer patients and allows tumors to grow and spread.

The newspaper pointed out that the new treatment provides a super-targeted dose of chemotherapy directly to cancer through a swarm of nanoparticles that stick to the tumor itself, and the chemotherapy works by killing fast-growing cancer cells, but often mistakenly attacks normal cells elsewhere in the body, causing severe side effects,
