The initial response to treatment and subsequent development of resistance to carboplatin are very important challenges. Use of nano drug delivery is a new method to replace standard chemotherapy. In this research, both non-PEGylated and PEGylated nanoparticles (NPs) were prepared by mini-emulsion polymerization of poly (butyl cyanoacrylate) (PBCA) NPs. Characteristics such as size, polydispersity index (PDI), zeta potential, drug release, and stability were examined. In addition, infrared spectroscopy was used for description of the produced NPs. Then, cytotoxicity effects of both formulations were studied on the A2780CIS ovarian cancer cell line with incubation for 24, 48, and 72h. Examination of characteristics of loaded carboplatin on the PBCA NPs under suitable laboratory conditions showed a positive effect of PEG on their properties. Cytotoxicity studies demonstrated greater toxicity with both formulations of nano-drugs than the free drug. The results indicated that PBCA NPs can be considered as suitable candidates for nano-drugs in chemotherapy.
