在这项研究中,我们在单细胞水平上探索了银纳米颗粒(Ag-NPs)神经毒性的快速评估。传统的对大细胞群的纳米毒性测定可能会隐藏在神经元细胞中经常发现的单个细胞的重要异质性。新纳米材料发现领域的发展远远领先于测量这些材料毒性的先进工具的发展。开发替代方法来快速、可靠和准确地评估纳米材料的毒性是可取的。在这里,我们提出了一种基于芯片的细胞集成微孔阵列设备,通过监测PC12细胞的胞吐功能来快速评估Ag-NPs的神经毒性。本研究结果证实了Ag-NPs的剂量依赖性毒性以及暴露于NPs时其胞吐功能的立即改变。
In this research, we explored a rapid assessment of silver nanoparticles (Ag-NPs) neurotoxicity at a single-cell level. Traditional nanotoxicity assays on large cell-populations may hide the important heterogeneity of individual cells often found in neuronal cells. The development in the area of new nanomaterial discoveries is far ahead of the development of advanced tools to measure these materials’ toxicity. Development of alternative approaches to assess nanomaterials toxicity rapidly, reliably, and accurately is desirable. Here, we present a chip-based, cell-integrated microwell-array device for rapid assessment of neurotoxicity of Ag-NPs by monitoring the exocytosis function of a PC12 cell. Results presented here confirm the dose-dependent toxicity of Ag-NPs and the immediate alteration of their exocytosis function when exposed to NPs.
