A pair of new articles suggests that cancer-fighting nanoparticles ought to be disc-shaped, not spherical or rod-shaped, when targeting cancers at or near blood vessels. 

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.

"The vast majority -- maybe 99 percent -- of the work being done right now is using nanoparticles that are spherical.
