ABSTRACT
Most women get breast cancer, 1.4 million cases are diagnosed annually worldwide.
Zinc oxide nanoparticle biosynthesis of olive leaves is a popular traditional leave
study. This study was aim to synthesised and characterised zinc oxide nanoparticles
using Olea europaea L to test their cytotoxic impact on breast cancer cell lines MDAMB 231, antioxidant, and antibacterial properties on gram-negative and gram-positive
bacteria. The GC-MS analysis shows that there are some bioactive compound presents
in Olea europaea L and the UV spectra analysis indicated the spectrum with the peaks
of 313, 285, 257, 227 and 201 nm with absorption respectively. The zeta size has
shown a size of 86.14 nm with a charge of -12.64 mV X-RAY Diffraction (XRD)
and the Fourier Transform Infrared Spectrophotometer (FTIR) has been used. The
antioxidant result shows an antioxidant activity of the ZnO NPs and Zn against the free
radicals while higher activity was recorded in Olea europaea L. The ZnO NPs, Zn and
Olea europaea L against the six bacterial has shown a zone of inhibition for the
following bacterial P. aeruginosa 29, E. coli 12, S. aureus 16, B. cereus 8, while the
two bacterial E faecalis 0, Legionella pneumophila 0, has not indicated any zone of
inhibition which has been found by other researcher of similar result E Faecalis,
legionella pnenumophila. DMEM-grown MDA MB 231 cells for positive control were
100% viable. After 24 hours of treatment, cell was reduced to 80%. The higher dose
reduced cells from 100% to 80% and after 48-hour of incubation there was 68% of
effects of ZnO NPs. Positive control of MDA MB 231 and DMEM as a media shown
100% viability in 24-hour at the beginning, Minor influence seen in 24-hour cell death
of 80%, while the positive control still maintains the cell viability at 100%. ZnO
nanoparticles activity caused shrank, aggregated, deformed, adhered, and proliferated
slower MDA MB 231 breast cancer cells as evident of Apoptosis and shrinkage
indicate cell death.
