Characteristics of the obtained cRGD-conjugated PICsomes.

Sample	cRGD contenta (mol %)	Diameterb (nm)	Diameterc (nm)	PDIb	Zeta potentiald (mV)
Ctrl-PICsome	0	92 ± 5	90 ± 12	0.085	−28
20%-cRGD-PICsome	23.4	86 ± 10	82 ± 21	0.094	−27
40%-cRGD-PICsome	40.4	94 ± 8	86 ± 21	0.016	−23
100%-cRGD-PICsome	97.5	92 ± 2	85 ± 23	0.072	−20

^aThe cRGD content was determined using ¹H NMR.

^bThe number average diameter, as determined using DLS (n = 10, mean ± s.d., s.d. = standard deviation).

^cThe number average diameter, as determined using TEM (n = 200, mean ± s.d.).

^dThe zeta-potentials were determined using a zetasizer.
