BACKGROUNG
The rising complexity and associated side effects of cancer treatments highlight the need for safer and more effective therapeutic agents. Carbon-based nanomaterials such as CDs have been gaining prominence for their unique characteristics, opening avenues for diverse applications such as fluorescence imaging, drug and gene transport, controlled drug delivery, medical diagnosis, and biosensing. Despite promising advancements in research, it remains imperative to scrutinize the properties and potential cytotoxicity of newly developed CDs, ensuring their viability for these applications.
METHODS
We synthesized four N-doped CDs through a hydrothermal method. Cell viability assays were conducted on A549 and UM-UC-5 cancer cells at a range of concentrations and incubation times, both individually and with the chemotherapeutic agent 5-fluorouracil (5-FU).
RESULTS
The obtained results suggest that the newly developed CDs exhibit suitability for applications such as bioimaging, as no significant impact on cell viability was observed for CDs alone.
背景
癌症治疗日益复杂且伴有副作用，这凸显了对更安全、更有效治疗药物的需求。诸如碳点（CDs）之类的碳基纳米材料因其独特特性而备受关注，为荧光成像、药物和基因转运、可控药物递送、医学诊断及生物传感等多种应用开辟了道路。尽管研究取得了令人鼓舞的进展，但仍有必要仔细研究新开发的碳点的性质及其潜在细胞毒性，以确保它们在这些应用中的可行性。
方法
我们通过水热法合成了四种氮掺杂碳点。在一系列浓度和孵育时间下，分别对A549和UM - UC - 5癌细胞以及与化疗药物5 - 氟尿嘧啶（5 - FU）一起进行细胞活力测定。
结果
所得结果表明，新开发的碳点适用于生物成像等应用，因为单独使用碳点时未观察到对细胞活力有显著影响。
