Nepeta deflersiana aerial part | Silver nitrate | Spherical 33 nm | HeLa cells | MTT assay, Neutral red uptake assay, DCFH-DA, rhodamine-123 | 5 μg/mL | ND-Ag NPs have the capacity of inducing apoptosis and necrosis cell death of HeLA cells through SubG1 cell cycle arrest | [260] |
Moringa olifera stem bark extract | Silver nitrate | Spherical 40 nm | HeLa cells | Annexin V/PI double-staining assay NRU, DCFH-DA, DAPI staining | – | The increased level of ROS revealed that most of the cells underwent induction of early apoptosis caused by oxidative stress, while many of the inhibitors that induce apoptosis show antioxidant activity | [261] |
Detarium microcarpum leaf extract | Silver nitrate | Spherical/rectangular 81 nm–84 nm | HeLa cells | Presto blue cell viability assay | 31.5 µg/mL | The synthesized NPs had inhibitory effect on cervical cancer cells | [262] |

Catharanthus roseus leaf extract | HAuCl4 | Spherical 25–35 nm | HeLa3T3 cell lines | MTT assay, AO/EtBr staining, DCFH-DA staining, Rhodamine 123 Caspases activity assay, Western blotting | 5 µg/mL | The cytotoxicity and apoptosis of human cervical carcinoma (HeLa) cells increased Caspase-3 was cleaved after being exposed Biosynthesized NPs for 24 h | [255] |
Pongamia pinnata leaf extract | HAuCl4 | Spherical 55 nm | HeLa cells Human embryonic kidney cell line: HEK293 | MTT assay, Flow cytometry, Rhodamine 123, Wound healing/cell migration assay | 200 µg/mL | Au NPs gets internalized into HeLa cells by endocytosis. Inside the cytosol, it exhibited cytotoxic effect by elevating intracellular ROS, perturbing the MMP, arresting cells at S-phase of the cell cycle and finally inducing cell death by apoptosis | [263] |

Brassica oleracea var acephala leaf extract | Copper sulfate | Spherical 60–100 nm | HeLa cells | MTT assay | 119.0805 μg/mL | The vitality of cancer cells declines as sample concentration rises, whereas cytotoxicity against HeLa cell lines rises as sample concentration rises | [264] |
Phaseolus vulgaris | Copper sulfate | Spherical, hexagonal 26.6 nm | HeLa | SRB assay, Hoechst 33,258 staining, DCFH-DA, Clonogenic assay | 0.5 and 1 µg/mL | In a dose-dependent manner Induced intracellular ROS generation | [259] |
Houttuynia cordata | Copper sulfate | Spherical 40–45 nm | HeLa | MTT assay, DCFH-DA, EtBr/AO staining, DAPI staining, Pi stainin, Q-RT-PCR | 5 µg/mL | Biosynthesized NPs inhibited cell proliferation and promoted apoptosis by targeting PI3K/Akt signaling pathways in HeLa cells | [265] |
Titanium oxide | |||||||
Coleus aromaticus leaf extract | TiO2 | Hexagonal shape 12–33 nm | HeLa | MTT assay | 34.45 µg/mL | Increased oxidative stress, destroyed the cell membrane, enhanced lipid peroxidation, lowered the level of glutathione (GSH), and eventually contributed to cells’ death | [266] |
