From: Pullulan-Based Nanoparticle-HSA Complex Formation and Drug Release Influenced by Surface Charge

Sample	D^a (nm)	PI^a	ZP^b (mV)
CHP	73.1 ± 3.6	0.243 ± 0.015	− (0.698 ± 0.14)
CHAP	116.9 ± 2.7	0.297 ± 0.023	+ (12.9 ± 0.13)
CHSP	156.9 ± 4.1	0.299 ± 0.074	− (15.4 ± 0.18)

PI polydispersity index
^aAverage diameter (mean value ± SD) determined by dynamic laser light-scattering with three times
^bZeta potential (measured by DLS)
