Scientists at ETH Zurich have developed a new microscopic particle for targeted drug delivery inside the human body.

The flower particles have a large surface area compared to their size, with tiny pores between the petals that can absorb a ...

These small particles are reminiscent of paper flowers or desert roses. Physicians can use them to guide medicines to a ...

For instance, researchers can use high resolution electron microscopy to take a snapshot through a thin cross-section or slice of a cell. In this way, they can see the structural detail and key ...
