By heating up small nanorods of gold with near-infrared light (NIR), the bacteria are killed, and the surface of the implant becomes sterile. The researchers are now presenting a new study that ...

The illustration shows how the gold nanorods heat up when illuminated with NIR light. At temperatures above 120 degrees Celsius, the gold rods begin to change shape, and their optical properties ...

According to a new study, however, a covering of bacteria-frying gold nanorods could keep that from happening. Bacterial infections at the sites of recently installed implants can be very serious ...
