CeO₂/MnFe₂O₄ nanocomposite: Structural, magnetic, electrochemical and cytotoxicity properties

초록

The synthesis and characterization of CeO2/MnFe2O4 nanocomposite is significant due to its potential uses in various sectors, including environment and energy storage. This nanocomposite, created through calcination at 600 degrees C, has received a lot of interest. However, worries about potential cytotoxicity have encouraged studies into its safe use in biological systems. This study investigates the material's cytotoxic properties to determine its impact on cell health. Electrochemical testing revealed good capacitance performance within the 0-0.5 V potential window, with a specific capacitance (Cs) of 76 F/g at a current density of 0.25 A/g, making it a prospective candidate for supercapacitor (SC) development. Despite the higher current density of 5 A/g, the electrode maintained 81.28 % of its capacitance retention. These findings highlight the nanocomposite's potential in SC applications. Furthermore, cell viability studies with normal mouse muscle fibroblasts (BLO-11) and murine colorectal cancer cells (CT-26) demonstrated high biocompatibility, with cell survival rates exceeding 82 %. These findings highlight the need to assess nanocomposite safety for potential biological applications.
