Physical characterization of ritonavir-loaded nanoparticles

Formulation	Particle size (nm)		Zeta Potential (mV)
Formulation	DLS^*(PI)	TEM^**	Zeta Potential (mV)
Unconjugated NPs	300 (0.10)	125 ± 6.3	−19.3 ± 0.5
TAT-conjugated NPs	340 (0.14)	157 ± 8.9	+2.4 ± 0.3

^*

Mean hydrodynamic diameter determined by dynamic light scattering (DLS). PI: Polydispersity index.

^**
