dc.description.abstractA neuronal microneedle, a single-crystalline silicon microneedle with fluidic
microchannels and microelectrodes, is developed for localized stimulation of and recording
from neural cells. The neuronal microneedle delivers drugs such as excitatory amino acids
at the cellular level as well as electrically records neural signals from neural cells. The
fluidic behavior, the mechanical stability, and the electrode-electrolyte interface impedance
of the fabricated neuronal microneedle were characterized, respectively. Then, the neural
cell responses of a brain of a male Sprague-Dawley rat to a 25μM kainic acid (KA)
stimulus were acutely monitored by using the developed neuronal microneedle.
