Extended Data Fig. 2: Cluster averages of two-dimensional images of silicages.
From: Self-assembly of highly symmetrical, ultrasmall inorganic cages directed by surfactant micelles

a, Around 19,000 single-particle cryo-EM images were sorted into 100 clusters20. b, Some of the projections (examples highlighted in a) exhibited features similar to those of simulated projections of dodecahedral cage structure. Also shown are projection models. Scale bars represent 10 nm.
