Previous experimental reports of hyperthermia with various nanostructures.

Geometry	Experimental reports
Spherical particles	While several initial studies reported efficacious heating of spherical nanoparticles [14–18], subsequent experiments suggested that Joule heating of the stock solution, instead of the differential heating of the spherical nanoparticles, was the cause of the temperature increase [19,20]. An electrophoretic mechanism was later demonstrated to account for the temperature increase in suspensions of gold nanoparticles with D < 10 nm [22].
Prolate spheroids	Recently, Ref. [29] reported heating of Ag nanowires under RF, with heating rate increasing with aspect ratio (as predicted above). A high rate of cell death was observed for HeLa cancer cells treated with Ag nanowires and RF. The calculations above provide theoretical evidence to spur more experiments with nanowires.
Oblate spheroids	No reports are available in the literature. The calculations above suggest that experiments with high-aspect-ratio nanodiscs should be considered.
