Abstract
Introduction: Recent advancements in nanomedicine have drawn attention to the use of zinc oxide nanoparticles as apoptotic agents to address triple-negative breast cancer. Halophila beccarii-mediated zinc oxide nanoparticles (Hb-ZnONPs) were fabricated using zinc acetate dihydrate as the precursor.
Methods: The fabricated nanoparticles were characterized based on morphological, structural, and elemental composition using SEM and XRD. The antiproliferative potential of Hb-ZnONPs was studied using the BT-549 cell line as an in vitro model, employing the MTT assay and Annexin V-FITC/PI-based flow cytometry analysis.
Results: The Hb-ZnONPs exhibited characteristic absorption maxima at 367 nm with a particle size of 35 nm and -44.7 mV stability. XRD confirmed the hexagonal wurtzite structure with an elemental composition of 62.3% Zn and 25.79% Oxygen. The Hb-ZnONPs demonstrated significant cytotoxicity against BT-549 cells, with 35.26% apoptosis at 5 μg/ml and 38.25% apoptosis at 10 μg/ml. However, cells in the late apoptosis stage increased from 14.48% at 5 μg/ml to 28.16% at 10 μg/ml, indicating a nearly twofold increase with the higher concentration.
Conclusion: Hb-ZnONPs may act as promising apoptotic inducers in the chemotherapy of breast cancer.
