Chitosan/ghatti gum polyelectrolyte complexes were synthesized using different proportions of chitosan (CH) and ghatti gum (GG). The optimum CH: GG ratio was 20:80, which produced highest product yield. Polyelectrolyte (PEC) samples were characterized by differential scanning calorimetry (DSC) and FT-IR spectroscopy. Matrix tablets using PEC as matrix and Diltiazem Hcl as a model drug were form...

We studied the formation in a salt-free solution of complexes between potassium poly(vinyl alcohol) sulfate (KPVS), a strong polyelectrolyte, and proteins with known amino-acid sequences: papain, human serumalbumin, lysozyme, ribonuclease, trypsin, and pepsin. Turbidimetric titration, togetherwith quasielastic light scattering (QELS), static light scattering (SLS), and electrophoretic light sca...

Nanosized hydroxyapatite (HA) powders have been synthesized by an inverse microemulsion system using cyclohexane, an anionic surfactant and aqueous solutions of calcium nitrate tetrahydrate and biammonium hydrogen phosphate in the presence of anionic and caionic polyelectrolyte with the inducement of ultrasound irradiation. Prepared HA in presence of anionic polyelectrolyte has a different morp...
