Characterization of PTX-loaded NPs and PTX-loaded NPs@PDA

Sample	Size (nm)	PDI	ZP (mV)	LC (%)	EE (%)
PTX-loaded NPs	122.6±3.9	0.136	−21.4±4.7	17.5±1.28	97.3±5.0
PTX-loaded NPs@PDA	141.8±5.8	0.121	10.9±1.5	16.8±1.05	94.1±3.6

Note: Size indicates particle diameter; n=3.

Abbreviations: EE, encapsulation efficiency; LC, loading content; NP, nanoparticle; NPs@PDA, NPs that had their surfaces modified with PDA; PDA, polydopamine; PDI, polydispersity index; PTX, paclitaxel; ZP, zeta potential.
