The normal function of neurons depends on the integrity of microtubule-dependent transport of cellular materials and organelles to/from their cell bodies or axon terminus. In this chapter, we describe the design and implementation of a fluorescence imaging method to visualize axonal transport in neurons directly. We combine a pseudo total internal reflection microscopy, quantum dot fluorescence labeling, microfluidic neuronal culture chamber, and single molecule detection methods to achieve a high spatial and temporal resolution in tracking nerve growth factor transport in dorsal root ganglia neurons.
