Gold, DNA Combination May Lead To Nano-Sensor
|
|
| Duke University scientists have developed intracellular biological sensors based on gold nanostructures with tethered DNA recognition molecules that can create signals from subtle changes in light reflecting off their nanoscale surfaces. By measuring color changes, researchers can tell what is happening at the molecular level, and the nanoparticles are small enough to pass through cell membranes.
