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.
