Encapsulation, drug loading efficiencies and drug content of various formulations.

Formulation code	Encapsulation efficiency (%)	Drug loading efficiency (%)	Drug content present in 5 mg of nanoparticle (w/w)
A1	91.98 ± 0.13	15.09 ± 0.18	0.94 ± 0.015
A2	75.87 ± 0.24*	11.59 ± 0.33*	0.77 ± 0.027*
A3	52.82 ± 0.21*	10.77 ± 0.14*	0.59 ± 0.07*
A4	63.94 ± 0.23*	12.8 ± 0.26*	0.66 ± 0.025*

Values are expressed as mean ± SD, n = 3. Encapsulation and loading efficiencies were expressed in percentage. Drug content was expressed in mg. (*) P < 0.05 as compared with respective A1 formulation.
