Nanoparticles: A simpler route to hollow carbon spheres

Hollow carbon nanoparticles are strong, conduct electricity well and have a remarkably large surface area. They show promise in applications such as water filtration, hydrogen storage and battery electrodes—but commercial ...

Multitasking plasmonic nanobubbles kill some cells, modify others

(Phys.org)—Researchers at Rice University have found a way to kill some diseased cells and treat others in the same sample at the same time. The process activated by a pulse of laser light leaves neighboring healthy cells ...

Calcium carbonate templates for drug delivery

(Phys.org) -- The fast and targeted delivery of drugs to the focus of a disease could soon be made easier. Helmuth Möhwald and his colleagues from the Max Planck Institute of Colloids and Interfaces in Golm, Potsdam, ...

Tiny rulers to measure nanoscale structures

With the advent of nanometer-sized machines, there is considerable demand for stable, precise tools to measure absolute distances and distance changes. One way to do this is with a plasmon ruler. In physics jargon, a "plasmon" ...
