Abstract :

In recent years, there is a lot of interest in synthesis of nanostructures as carriers for drug delivery.These structures are considered as a highly effective drug delivery system due to controlling drugrelease, protecting the pharmaceutical molecule, and environmentally friendly. In this study, thesynthesis of chitosan nanoparticles was carried out by chemical method. The nanoparticles size wasmeasured by dynamic light scattering (DLS). Also, it was used from atomic absorption spectrometry(AAS), FTIR and transmission electron microscopy (TEM) to confirm the loading of antibiotic ontonanoparticles and to calculate the percentage of the drug loaded. In addition, it was used forclarithromycin as antibiotic. The antibacterial activity was studied by the disc-diffusion methodand the effect of different concentrations of the drug in nano-carriers were investigated and it wasdetermined the optimum antibacterial activity of drug nanocarrier was happened in concentration0.6 gr/10 ml.
