BNL | Center for Functional Nanomaterials (CFN) | Tiny Nanocubes Help Scientists Tell Left from Right

BNL | Center for Functional Nanomaterials (CFN) | Tiny Nanocubes Help Scientists Tell Left from Right | Biosciencia News | Scoop.it
A team of scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Ohio University has developed a new, simpler way to discern molecular handedness, known as chirality, which could improve drug development, optical sensors...
Biosciencia's insight:

In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive. That's because, in biology, "left" and "right" molecular designs are crucial: Living organisms are made only from left-handed amino acids. So telling the two apart is important—but difficult.

Gold Nanoparticles Uncover Ovarian Cancer Genetics

Gold Nanoparticles Uncover Ovarian Cancer Genetics | Biosciencia News | Scoop.it
Researchers have found the mechanism ovarian cancer cells use to avoid toxicity from gold nanoparticles, and have devised a way to get around it.
Biosciencia's insight:

Positively charged gold nanoparticles could be used as a targeted therapy for cancer.
