Soft X-Ray Method Promises Nanocarrier Breakthroughs for Smart Medicine

Before the huge potential of tiny nanocarriers for highly targeted drug delivery and environmental clean-up can be realized, scientists first need to be able to see them.

Currently researchers have to rely on attaching fluorescent dyes or heavy metals to label parts of organic nanocarrier structures for investigation, often changing them in the process. A new technique using chemically-sensitive "soft" X-rays offers a simpler, non-disruptive way of gaining insight into this nano-world.

In a study published by Nature Communications, a research team demonstrates the capability of the X-ray method on a smart drug delivery ...
