Z-average diameters and polydispersity of control liposomes and peptide-conjugated liposomes

Preparation	Size (nm)	PDI
Control liposomes (no peptide)	90 ± 5	0.220 ± 0.010
A371-PCL	110 ± 10	0.170 ± 0.015
Scr-A371-PCL	200 ± 100	0.270 ± 0.020
A415-PCL	91 ± 10	0.420 ± 0.050
Scr-A415-PCL	98 ± 20	0.264 ± 0.020
A417-PCL	82 ± 20	0.373 ± 0.20

Note: Mean particle diameters (Z_av) both with and without the targeting peptide were determined by dynamic light scattering and reveal the liposomes to be monodispersed, with narrow particle size distributions.

Abbreviation: PDI, polydispersity index.
