Traganth is a biocompatible and biodegradable polysaccharide which has attracted the attention of researchers in different fields like cosmetics, hygiene, tissue engineering, drug release, food, textiles and pharmaceuticals. It is well known that particles with submicron size, show totally different characteristics and behavior in comparison to their bulk form. Nanoparticles can be produced through processes like emulsification, coacervation and electrospraying. It is believed that electrospraying is capable of producing spherical, smaller and more uniform particles. In order to electrospray polymeric particles, at first the polymer must be dissolved in a suitable solvent or a mixture of solvents if needed. The polymer solution is then fed by a fine metering system to the tip of the nozzle in a electric field produced by a high voltage power supply. The electric forces induced on the drop at the exit of the nozzle overcome the surface tension of the drop and the initial breaking up occurs. After the evaporation of the solvent the size of the drop is decreased and these initial drops break up to smaller and smaller drops due to the repulsion of the electrostatic forces on the drops as they travel from the tip of the nozzle to the collector. This breaking up is known as coulombic explosions. Electrospraying has been employed to produce nanoparticle such as chitosan, insulin, fibroin, sericin and keratin nanoparticles. Up to now, traganth as well as traganthh-oligochitosan has been produced by colloidal solution process. However, literature shows no report on electrosprayed traganth nanoparticles. This research aimed at electrospraying traganth nanoparticles. In order to carry out this task, traganthh in water and water- ethanol(70:30) were electrosprayed and the effect of parameters such as viscosity, applied voltage, nozzle-collector distance, feed rate and the kind of solvent were studied on the morphology of the electrosprayed traganth nanoparticles. The range for traganth concentration, nozzle-collector distance, voltage and feed rate was 0.1 – 0.3% (w/v), 10 -20 cm, 15 – 25 and 0.02 – 0.06 ml respectively. These data were obtained by trial and error experiment as there was no information already available in this field. In the second part of this research the soluble part of traganthh in water was separated by deesterification with sodium hydroxide. The water soluble traganth was also electrosprayed. The results showed that electrospray is capable of producing nanoparticles with an average size in the range of 30 – 50 nm depending on the electrospraying conditions. The water soluble traganth gave rise to even smaller particles. As the viscosity of water soluble traganth was low, electrospraying of traganth with concentrations of even 2% was possible. It was also found that, lowering feed rate, increasing nozzle collector distance and voltage decreases the average size of the electrosprayed traganth nanoparticles. FTIR proved the absence of ester groups after deestrification. FTIR for electrosprayed nanoparticles showed a higher intensity for C=O at 1417 wave number. XRD studies showed an amorphous or very small crystallites for traganth, but water soluble traganth was capable of crystallizing.
