Particle Size, Zeta Potential and Entrapment Efficiency Measurements for Lip-Se and Man-Lip-Se Formulations and Particle Size and Zeta Potential for Man-Lip-Se II after Lyophilization and Reconsitution

Nanoparticles	Particle size (nm)	Zeta Potential (mV)	EE initial
Lip-Se I	148 ± 68.7	−54.7 ± 4.07	73.3 ± 2.49%
Lip-Se II	154 ± 23.0	−23.4 ± 1.58	74.0 ± 3.57%
Man-Lip-Se I	156 ± 73.4	26.1 ± 1.95	73.3 ± 2.49%
Man-Lip-Se II	158 ± 28.9	33.2 ± 0.89	77.3 ± 2.34%
Reconstituted Man-Lip-Se II after lyophilization	159 ± 62.4	31.5 ± 1.21	99.5 ± 2.46%a

^aThe represented data is for the Se assay since the unentrapped Se was removed before lyophilization
