Pressure ejection is the controlled expulsion of substances using applied air pressure from pulled multibarrel glass capillaries. The technique is frequently employed in neuroscience for the localized delivery of reagents to select brain regions of interest. Our lab has recently adapted a method to prevent unintentional leaking of reagent into the recording site. Here, those principles have been adapted to allow the local delivery of non-electroactive substances in vivo. A pressure-ejected system was coupled to fast scan cyclic voltammetry for real-time monitoring of ejections and a dye was introduced into the pipet barrels for visualization of ejection progress. This study shows that the dye had no effect on the electrically evoked dopamine response. Additionally, it shows the method proposed is applicable for fabrication and local employment of electroinactive reagents delivery of in vivo.
