This project aims to engineer nanomaterials by utilising gold nanochemistry and neural tracing capabilities of plant-based, nontoxic proteins. In a significant departure from current nanomaterials being developed, functionalising nanoparticles with the tracers enable them to undergo path-specific axonal retrograde transport, transneuronal transport, and anatomical tract flow to bypass the blood-brain barrier. Microfluidics will be used to characterise the neuronal activities of the synthesised nanoconjugates of different sizes and compositions to understand their bio-interactions with axons, synapses, and neuromuscular junctions. The results will lead to a new class of functional nanomaterials as well as cell-based functional assays.

该项目旨在利用金纳米化学和植物性无毒蛋白质的神经追踪功能来设计纳米材料。与当前正在开发的纳米材料有很大不同，用示踪剂功能化纳米颗粒使它们能够经历路径特异性轴突逆行运输、跨神经元运输和解剖道流动以绕过血脑屏障。微流体将用于表征不同尺寸和成分的合成纳米缀合物的神经元活动，以了解它们与轴突、突触和神经肌肉接头的生物相互作用。研究结果将催生一类新型功能纳米材料以及基于细胞的功能测定。
