Preparation and Characterization of Gum Nanoparticles Using Response Surface Method: Evaluation of Its Anti-Bacterial Performance and Cytotoxicity.

This study aims to prepare a novel, natural nanoparticle (NP) as a drug carrier, which also has inherent therapeutic effects. Pistacia khinjuk gum NPs were prepared and Response surface methodology (RSM) was used for statistical analysis of data and optimizing the size of NPs. NPs were in the range of 75.85-241.3 nm. The optimization study was carried out, and an optimized size (70.86nm) was obtained using DMSO as a solvent. The volume of the organic phase was 111.25µl, and the concentration of gum was 1% w/v. The cell viability assay was performed on the pure gum and NPs toward β-TC, MCF7, and HT29 cell lines. It was observed that NPs have higher cytotoxic activity in comparison with pure gum, and that the ICvalue was achieved at 1% of NPs in β-TC3 cells. The obtained NPs demonstrated antibacterial activity against two bacterial strains (Pseudomonas aeruginosa and Staphylococcus aureus). Altogether, according to the obtained results, these NPs with inherent cytotoxicity and antibacterial activity are an attractive carrier for drug delivery.
