Facile green synthesis of ZnFe2O4/rGO nanohybrids and evaluation of its photocatalytic degradation of organic pollutant, photo antibacterial and cytotoxicity activities

One-step preparation, characterization, and anticancer potential of ZnFe2O4/RGO nanocomposites

“…In this work, the MTT experiment was carried out on two different cancer cell lines (MCF-7 and A549) to assess the anticancer activity of synthesized samples. It was observed that ZnFe 2 O 4 /RGO NCs exhibited higher cytotoxicity towards the cancer cell lines (MCF-7 and A549) compared to pure ZnFe 2 O 4 NPs exhibiting IC50 around 50 for 24 h. At the same interval time, previous studies have observed significant cytotoxicity of metal with RGO in various cancer cell types, including HepG2, and A549 cells, with IC 50 concentrations of approximately 100 µg/mL and 250 µg/mL ( Alaizeri and Alhadlaq, 2022 , Krishnan et al, 2021 ). Our results suggest that RGO doping in ZnFe 2 O 4 NPs enhances their anticancer performance against human cancer (MCF-7 and A549) cells.…”

“…Due to their unique properties, many researchers have been interested in applying metal oxide NPs and graphene-based NCs in biomedicine and cancer therapy ( Alafaleq et al, 2023 , Alaizeri et al, 2022 , Arunima Rajan et al, 2019 , Krishnan et al, 2021 , Sarala et al, 2020 , Tabrez et al, 2022c , Tabrez et al, 2022b ). In this work, the MTT experiment was carried out on two different cancer cell lines (MCF-7 and A549) to assess the anticancer activity of synthesized samples.…”

“…Interestingly, zinc ferrite (ZnFe 2 O 4 ) NPs have been extensively studied in potential biomedical applications due to their unique physiochemical properties ( Aarti et al, 2022 ). Krishnan et al ( Krishnan et al, 2021 ) prepared ZnFe 2 O 4 /RGO NCs via a facile green approach. This study showed that the ZnFe 2 O 4 /RGO NCs have a high cytotoxicity effect against human lung cancer(A549) cells.…”

Photocatalytic Degradation of Methylene Blue and Anticancer Response of In2O3/RGO Nanocomposites Prepared by a Microwave-Assisted Hydrothermal Synthesis Process

“…For example, ZnO/RGO NCs [ 17 ], ZnO-MoS 2 /RGO NCs [ 18 ], MoS 2 -Fe 2 O 3 /RGO NCs [ 19 ], Ag/ZnO/RGO NCs [ 20 ], and Ce/ZnO/RGO NCs [ 21 ] have been successfully prepared and have potential in biomedicine and environmental remediation applications. Different approaches including chemical, physical, and biological methods have been used to synthesize metal oxide NPs with RGO as NCs [ 22 , 23 , 24 ]. Bibi et al [ 25 ] reported the synthesis of Fe 2 O 3 -TiO 2 /RGO NCs through a hydrothermal approach, which demonstrated remarkable methyl blue degradation capabilities due to the synergistic effect between Fe 2 O 3 -TiO 2 NPs and RGO.…”
