量子点对口腔鳞癌细胞活性影响的研究

目的 探讨量子点对口腔鳞癌活细胞的影响。 方法 通过MTT法检测不同浓度量子点对口腔鳞癌细胞活性的影响。 结果 在4 、8h时各实验组与空白对照组无统计学意义（P＞0.05）；在12 、16h及20h时，除量子点终浓度为20nmol/L组与空白对照组无统计学意义（P＞0.05），其它各组与空白对照组有统计学意义（P＜0.05）。 结论 量子点浓度低于20nmol/L时，对细胞活性无明显的影响。

Explore the influence of quantum dots on the oral squamous living cells

Objective explore the influence of quantum dots on the oral squamous living cells. Methods Concentrations of quantum dots were the activity of oral squamous cell carcinoma by MTT assay. Results Each experimental group and control group was not significant at 4 hours and 8 hours (P> 0.05);Quantum dots final concentration of 20nmol/L group and blank control group were not statistical significant at 12 hours, 16 hours ，20 hours (P> 0.05),and the other group and blank control group were statistically significant (P <0.05). Conclusion Concentration of quantum dots have no significant influence on growing of cell less than 20nmol/L.
