Abstract:
This paper presents the results of the interaction of graphene oxide (GO) on MDA-MB-231 and SW-954 cancer cell lines. The tests were carried out in two variants. In the first one, GO was sprayed on a Petri dish and then, the cancer cell lines were cultured. In the second variant, the cells were covered with an aerosol containing GO. In both variants, cancer cell lines were incubated and tested every 24, 48, and 72 h. After each time period, cell viability and surface morphology were measured. The tests after 72 h showed that coating with GO aerosol caused a reduction in cell viability by 52.7% and 26.4% for MDA-MB-231 and SW-954 cancer cell lines, respectively, with respect to a reference sample (without the influence of GO aerosol). Tests where GO is a culture medium demonstrated a decrease in cell viability by approximately 4.3% compared to a reference sample for both considered cell lines.
Insights
Graphene oxide (GO) aerosol significantly reduced MDA-MB-231 and SW-954 cancer cell viability. GO in culture medium showed minimal impact on cancer cell survival.
Area of Science:
- Biomedical Engineering
- Materials Science
- Oncology
Background:
- Graphene oxide (GO) is a novel nanomaterial with potential biomedical applications.
- Understanding GO's interaction with cancer cells is crucial for developing new therapeutic strategies.
- MDA-MB-231 and SW-954 are aggressive cancer cell lines relevant for in vitro studies.
Purpose of the Study:
- To investigate the cytotoxic effects of graphene oxide (GO) on MDA-MB-231 and SW-954 cancer cell lines.
- To compare the impact of different GO application methods (aerosol vs. culture medium) on cancer cell viability.
Main Methods:
- Two experimental variants were employed: GO aerosol exposure and GO incorporation into the culture medium.
- Cancer cell lines (MDA-MB-231 and SW-954) were incubated with GO for 24, 48, and 72 hours.
- Cell viability and surface morphology were assessed at each time point.
Main Results:
- GO aerosol application led to a significant reduction in cell viability: 52.7% for MDA-MB-231 and 26.4% for SW-954 after 72 hours.
- Incorporating GO into the culture medium resulted in a modest decrease in cell viability (approx. 4.3%) for both cell lines.
- Surface morphology changes were observed, indicating cellular interaction with GO.
Conclusions:
- Graphene oxide aerosol exhibits potent cytotoxic effects on MDA-MB-231 and SW-954 cancer cells.
- The method of GO application significantly influences its anti-cancer efficacy.
- GO shows promise as a potential agent for cancer therapy, particularly when delivered via aerosol.
