Fig. 2. Transferrin was enriched in the hard protein corona and the extent of enrichment was susceptible to the exposed facets of CdSe and CdS nanocrystals.

The protein coronas were formed in fetal bovine serum. The size of the circles represented the enrichment factor of proteins in the hard corona, and the difference in the protein enrichment factors between the two different-faceted materials is shown in the bar graph. The proteins were ranked according to the decreasing difference in the enrichment factor of proteins detected from the hard coronas on the two different-faceted CdSe nanoparticles (a, CdSe-p-A: dark red bubble; CdSe-p-B: light red bubble), CdSe nanorods (b, CdSe-r-A: dark blue bubble; CdSe-r-B: light blue bubble), and CdS nanorods (c, CdS-r-A: dark green bubble; CdS-r-B: light green bubble).
