ABSTRACT
In recent years, encapsulation of drugs and antigens in hydrogels, specifically in calcium alginate particles, is an interesting and practical technique that was developed widespread. It is well known that alginate solution, under proper conditions, can form suitable nanoparticles as a promising carrier system, for vaccine delivery. The aim of this study was to synthesis alginate nanoparticles as protein carrier and to evaluate the influence of various factors on nanoparticles properties. Alginate nanoparticles were prepared by ionic gelation method. Briefly, various concentrations of CaCl2 were added to different concentrations of sodium alginate dropwisly by homogenizing magnetically at 1300 rpm. The effects of homogenization time and (-) rate were investigated on nanoparticle feature. Nanoparticles were characterized for their morphology and size distribution. Evaluation of loading capacity and loading efficiency of nanoparticles were performed by using various concentration of BSA. The concentration of 0.3%w/v sodium alginate and 0.1%w/v CaCl2 solution, homogenization time 45 min and homogenization rate 1300 rpm were observed as suitable condition - to prepare optimized nanoparticles. It can be concluded that the properties of nanoparticles are strongly dependent on the physicochemical conditions. The optimum concentrations of alginate and CaCl2and appropriate condition led to forming desirable nanoparticles that can be used as carrier for drug and vaccine delivery.
