Researchers: gold nanoparticles improve PCR

July 13, 2005 — Six researchers from Shanghai Jiao Tong University claim to have found that the polymerase chain reaction (PCR), the basis of modern genetic testing methods, works better in the presence of gold nanoparticles.

The researchers found that the presence of gold nanoparticles yields fewer errors in PCR, and therefore makes it possible to use smaller DNA samples from the start. The research was sponsored by the state-owned R&D organization, the Chinese Academy of Sciences.
