Gold Molecules May Destroy Prostate Cancer Cells
Each gold-based molecule is covered with peptide chains that facilitate binding to the cancerous cells. Without these chains, the molecules would be quite toxic. However, once injected into the blood, these golden compounds—which are shaped like popcorn—snare up to 50 cancer cells around them.
The researchers who developed the technique said that physicians may then expose these clusters to surface-enhanced Raman spectroscopy, which is a medical imaging process that allows doctors to see where the gold particles are.
The team concluded that when exposed to a particular kind of light, the molecules heat up and kill the cancer cells around them. The alternative therapy is still in the trial phase.
Prostate carcinomas are the most common cancer among American men, according to the American Cancer Society (ACS).
