Table I.

The Characterization of the Squarticles by Particle Diameter, Polydispersity Index (PDI), Zeta Potential, and Drug Encapsulation Percentage

Type	Size (nm)	PDI	Zeta potential (mV)	DPCP encapsulation (%)	Minoxidil encapsulation (%)
NLC	177 ± 3	0.24 ± 0.01	−54.0 ± 0.2	83.7 ± 2.1	63.3 ± 0.5
NE	193 ± 1	0.25 ± 0.02	−56.6 ± 1.1	78.5 ± 7.1	63.5 ± 1.1

Each value represents the mean ± SD (n = 3 for size, PDI and zeta potential, n = 4 for drug encapsulation)
