Patchy particles show promise for drug delivery
U. PENN (US)—A team of physicists, chemists, and engineers has demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules. The particles may one day serve as drug-delivery vehicles and perhaps be used in small batteries that store and release charge. (more…)

‘Green’ foam that’s cheap and dirty
“The flexibility of the clay aerogel composites is amazing,” says engineering professor David Schiraldi, who adds that almost anyone can make the composites if they have pure clay in a form that resembles cat litter pellets, a blender, and a $50,000 freeze dryer.

Training DNA to detect pathogens
In the presence of certain pathogens, DNA-based molecules form chains and curl up into spheres. Visible here as red dots, the spheres are shown entering cells, which demonstrates their drug delivery capabilities. (Credit: Luo Labs)
