The four phases of a corona characterization include: (1) ENM exposure to biofluids and ENM characterization (red bar), (2) isolation of absorbed biomolecules and preparation for analysis (orange bar), (3) separation of biomolecules and spectroscopic characterization (green bar), and (4) informatic identification of the corona population and analysis.
