研究目的
To examine the cytotoxicity of NPs in different cancer cells and compare them with normal cells.
研究成果
NPs synthesized by laser ablation exhibit a pronounced cell killing effect in cancer cells without causing damage to normal cells. The study provides a new perspective on cell biology research in nanomedicine and paves the way for the simple and safe procedure of nanoparticle synthesis and their application in the management of cancer.
研究不足
The study focuses on the cytotoxic effects of nanoparticles on specific cancer cell lines and normal cells. Further experiments are needed to decipher the molecular mechanism of cytotoxicity and cell death for a better understanding of effects and successful treatment of cancers.
1：Experimental Design and Method Selection:
Laser ablation was used to synthesize nanoparticles in distilled water. The biological effects of these nanoparticles on normal and cancer cells were studied by examining cell morphology, proliferation, and viability.
2：Sample Selection and Data Sources:
Human ovarian cancer cell lines SK-OV3; murine Melanoma-B16F10; human colon Cancer- HT-29 and Murine fibroblast cells- NIH3T3 were used.
3：List of Experimental Equipment and Materials:
Nd-YAG laser, EDAX equipped SEM instrument HITACHI S3400N, Microtrac DLS instrument, DMEM medium, Fetal Bovine Serum, MTT reagent.
4：Experimental Procedures and Operational Workflow:
Cells were treated with nanoparticles at different concentrations, and cytotoxicity was assessed using MTT assay. DNA fragmentation assay was performed to study apoptosis.
5：Data Analysis Methods:
The effect of NPs on cell viability was measured in triplicate, and the experiments were repeated at least twice. DNA fragmentation was analyzed using agarose gel electrophoresis.
