Correction to: A microfluidic platform for continuous monitoring of dopamine homeostasis in dopaminergic cells

The legend in Figure 4a in the previously published version of this article contained erroneous units. The correct units are given in the caption–that is, 1 µM (black), 500 nM (red), 100 nM (blue), 50 nM (cyan), 10 nM (pink), and 0 nM (1× PBS solution, brown).
