Determining the best shape for cancer-fighting nanoparticles

As the field of nanomedicine matures, an emerging point of contention has been what shape nanoparticles should be to deliver their drug or DNA payloads most effectively. A pair of new papers by scientists at The Methodist Hospital Research Institute (TMHRI) and six other institutions suggests these microscopic workhorses ought to be disc-shaped, not spherical or rod-shaped, when targeting cancers at or near blood vessels.

Repelling the drop on top

It would make life a lot easier if the surfaces of window panes, corrosion coatings or microfluidic systems in medical labs could keep themselves free of water and other liquids. A new simulation program can now work out just how such surfaces have to look for a variety of applications.
