Smaller Than A Virus, New ‘Nanocage’ Could Pack A Big Punch Against Cancer

A team of engineers are hoping the 12-sided cage they developed will one day help fight cancer. Made from self-assembling silica, the nanocage is only 11 nanometers across—for comparison’s sake, a human hair is about 100,000 nanometers across. Silica particles can safely traverse the body, and as such might one day be effective vehicles for transporting various drug molecules.
