Fig. 5

Average fluorescence per cell measured after 1-hour incubation of polymersomes with BECs and macrophages as a function of ligand numbers for the angiopep peptides (A) and PMPC chains (B) and angiopep peptides mixed with 200 PMPC chains (C). The blue line shows the selectivity index calculated using the BECs as target and the macrophages as sentinel cells.
