微米级的 3D 打印可以快速制作用于神经元细胞培养的聚合物器件的原型设计。作为原理验证,神经元之间的结构连接受到影响神经突生长的屏障和通道的限制,而这种操作的功能后果是通过细胞外电生理学观察到的。

我们对大脑结构和功能之间的关系非常感兴趣,特别是在微电路水平上。我们经常采用简化的实验制剂,例如解离的神经元细胞培养物,因为它们是研究电活动、突触传递以及整体集体状态出现的宝贵模型。我们提出的方法非常适合快速制造微尺度聚合物器件。

这可以立即用于培养皿中模块化神经网络的实验研究,并且不需要高水平的软光刻技术专长。这种方法和我们简单的概念验证允许设计模块化神经元网络,我们可以在其中定义结构并控制生物信号的流动。药物筛选和病理状况研究立即受益于这些复杂的体外神经元网络。
