Preparation of CoS Nanoparticles-Cisplatin Bio-Conjugates and Investigation of Their Effects on SH-SY5Y Neuroblastoma Cell Line

Abstract

Neuroblastoma is one of the most widely seen under the age of 15 tumors that occur in the adrenal medulla and sympathetic ganglia. Cisplatin, an antineoplastic drug, is a Platinum-based compound and is known to inhibit the proliferation of neuroblastoma cells. Effective applications of nanoparticles in biomedical areas such as biomolecular, antimicrobial detection and diagnosis, tissue engineering, theranostics, biomarking, drug delivery, and anti-cancer have been investigated in many studies. This study aims to prepare the bioconjugates of CoS (cobalt sulfide) nanoparticles (NPs) with cisplatin combination groups and to evaluate their effects on the neuroblastoma cell line. Nanoparticle synthesis was done using the green synthesis technique using Punica granatum plant extract. The size and shape of CoS NPs were characterized by SEM, FT-IR, and XRD. Zeta potential was confirmed by the DLS study. For this purpose, the SH-SY5Y neuroblastoma cell line was cultured in a suitable cell culture medium. Cisplatin 5 mu g and different concentrations (Cisplatin + CoS NPs bioconjugates (5, 10, 25, 50, 75 mu g) doses were applied to SH-SY5Y neuroblastoma cell lines for 24 h. TAC, TOS and MTT tests were performed 24 h after the application. According to the MTT test results, cisplatin and CoS NP combinations reduced the proliferation of neuroblastoma cells by 78 to 57% compared to the cisplatin control. From the findings obtained; the most effective Bio-conjugate group was Cisplatin 5 mu g/mL + CoS 75 mu g/mL.
