Anti-Cancer Activity (Cytotoxicity Evaluation) Of Eto-
Nps 
Since the mutation of 
MDA-MB-231 
cell line growth typically 
occurs in an uncontrolled way either in 
a small lobe or ducts 
pathway of the breast. 
Often, these cell lines can also travel to 
other 
parts of lymph nodes under arms further this causes 
cancer in additional parts of the body [35] to estimate the toxic 
activity of ETO-NPs against these human breast cancer-producing 
cells, MTT assay was used in vitro using human breast 
adenocarcinoma MDA-MB-231 cells. Various concentrations (5, 
10, 20, 25, and 50 micro g/ml) of ETO-NPs have been treated 
on MDA-MB-231 cells up to 48 hours to study the cytotoxicity 
which is shown in ( Figure 9). Since ETO-NPs interact with 
MDA-MB-231 cells causing cell shrinkage which resulted in 
lower viability of MDA-MB-231 cells.
