Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today. A team of scientists at Washington Univ. in St. Louis is currently working on a magic bullet for cancer. But their bullets are gold rather than silver.

Taking gold nanoparticles to the cancer cell and hitting them with a laser has been shown to be a promising tool in fighting cancer, but what about cancers that occur in places where a laser light can’t reach? Scientists at the Georgia Institute of Technology have shown that by directing gold nanoparticles into the nuclei of cancer cells, they can not only prevent them from multiplying, but can kill them where they lurk.

Diamonds and gold may make some hearts flutter on Valentine's Day, but in a Univ. at Buffalo laboratory, silver nanoparticles are being designed to do just the opposite.

Using lasers and nanoparticles, scientists at Rice Univ. have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make "nanobubbles" by zapping gold nanoparticles inside cells.

Scientists at Georgia Tech and the Ovarian Cancer Institute have further developed a potential new treatment against cancer that uses magnetic nanoparticles to attach to cancer cells, removing them from the body. The treatment, tested in mice in 2008, has now been tested using samples from human cancer patients.

Scientists at the Univ. of California, Berkeley, have created smart nanoprobes that may one day be used in the battle against cancer to selectively seek out and destroy tumor cells, as well as report back on the mission's status.

Researchers at MIT and Harvard Medical School have built targeted nanoparticles that can cling to artery walls and slowly release medicine, an advance that potentially provides an alternative to drug-releasing stents in some patients with cardiovascular disease.

A Northwestern Univ. study shows that coupling a magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and, thus, vivid image contrast.

Gold’s non-toxic nature had led to much experimentation with nanostructures made from this metal. But until recent efforts by NIST scientists, there were no guidelines as to how nanoparticle size would affect interactions with proteins. These observations of behavior may help designers produce predictable effects in potential medical applications.

A team of researchers in California and Massachusetts has developed a “cocktail” of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors.
