How toxic are nanomaterials? A group of scientists from US and Korea has shown that nanostructured composite microspheres can be easily prepared using ultrasound in a non-toxic manner. These microspheres were created to act as drug carriers, in particular to deliver a potent Alzheimer’s Disease drug which is in clinical trials. Before drug delivery, however, the scientists had to show that their carrier was not itself toxic to cells.
“With increasing concerns that synthetic nanomaterials …

You’ve probably seen one of those tedious science videos where they drop a tiny nugget of lithium or sodium into a toughened glass bowl half full of water and watch the metal fizz and splutter.
Exciting, huh?
They might even have gone so far as to add an even smaller nugget of potassium, which in the most exciting moment might smash the bowl with its violence.
However, …

This week, in my news round-up on ChemWeb, we discover a chilly reminder of water’s bizarre behavior that could make cryopreservation science fact rather than fiction, a new understanding of the underlying cause of Parkinson’s disease, and discover that Swiss chemists have peered into their crystal ball to find new materials and explain some old ones. Also in this week’s news, simultaneous sensing for sensitive science and a way to clean up the infernal …
