Molecular Electrodes Help Detect Cancer

Molecular Electrodes Help Detect Cancer
Aug-31-18
Gold-plated nanoparticles that attract microRNA could lead to earlier detection of cancer from blood samples.

A reduced activity of microRNA can be a signal of some cancers, but collecting and counting these tiny molecules can be time-consuming. To make it easier to detect the microRNA, a team from New South Wales modified gold-plated nanoparticles with DNA that matched the microRNA—creating a “disposable electrode” that links to the targeted molecules. This makes the microRNA much easier to collect, and reduces the waiting time for results from 12 hours to 30 minutes.
