Using light to tune silver nanoparticles opens door to better imaging and much more
CORVALLIS, Ore. – Researchers have discovered a way to use ultraviolet rays to precisely adjust the size and shape of silver nanoparticles, tiny but hugely important bits of matter for applications including electronics, environmental monitoring and medical imaging.
In addition, the scientists found a technique for making the silver nanoparticles, whose specific properties depend on how big they are and what form they take, stable in the presence of light and oxygen, helping to ensure consistent performance over time.
