Hollow Disc and Sphere-Shaped Particles from Red Blood Cell Templates
Figure 2
(a) Gold discs with a thick layer of gold prior to sintering at 500°C, (b) a 300–400 nm thick
layer of gold deposited on the blood cells from repeated coatings of gold prior
to sintering. The arrows indicate excess colloidal gold, (c) an SEM image of a
red blood cell that bursts because the gold shell was too thin to contain it.
