Nanoribbon Trojan Horse Slips Drugs into Cells
The outer membrane of a cell is like a bouncer at an exclusive nightclub; it will only let privileged chemicals in. Now three scientists at Yonsei University in Korea have designed a tiny ribbon that can smuggle drugs, dyes, and other small chemicals into cells.
The nanoribbon could reduce the toxicity of drugs that have difficulty entering cells. Such drugs are usually given in large doses with the hope that a few molecules will find their way inside cells. But if all of the drug molecules can get inside, a much lower dose could be given.
