Webanalyzed using a zeta-potential and particle size analyzer (ELSZ-1000, Photal, Otsuka electronics) in an appropriate buffer. FTIR spectra were recorded on a FTIR-350 spectrometer (JASCO, Japan) by the Weband a particle size analyzer (Photal OTSUKA Electronics, Tokyo, Japan). An aliquot of the formulations (5 μL) was diluted in 1 mL of distilled water and agitated for 3 min to produce a uniform distribution as well as an adequate concentration for each measurement. The average of tripli-cate measurements was taken for all the formulations.
