Characterization of liposomes with respect to particle size, polydispersity, charge, and protein coupling yield.

	Particle size (nm)	Polydispersity	Zeta potential mV	µg protein/µmol PL
α−hEGFR-IL	95.2 ± 3	0.181 ± 0.045	−1.99 ± 0.067	97.6
hIgG-IL	119 ± 12	0.199 ± 0.091	−0.042 ± 0.042	135.1
Naked liposomes	84.24 ± 5	0.079 ± 0.064	−0.06 ± 0.023	N/A

EGFR-IL: liposomes coated with antiepidermal growth factor receptor (EGFR) antibody; hIgG-IL: liposomes coated with non-immune IgG; naked liposomes: liposomes without antibody conjugated to the surface; PL: phospholipids.
