Targeting quantum dots to deliver SiRNA therapy

Take a quantum dot, add a coating of poly(ethylene glycol) (PEG), and attach a homing peptide and a piece of small interfering RNA (siRNA), and the result is a targeted nanoparticle that can stop the production of a specific protein by a targeted cell.

Watching an object go quantum

Build a pendulum small enough, and it will violate Newton's classical laws of mechanics, following quantum rules instead. Some researchers hope to observe such violations by cooling a tiny wobbling object to very low temperatures.
