Facile fabrication of flexible glutamate biosensor using direct writing of platinum nanoparticle-based nanocomposite ink.
Electrochemical Evaluations of Fractal Microelectrodes for Energy Efficient Neurostimulation
The findings indicate that the increase in electrode perimeter leads to an increase in maximum charge injection capacity and found that the electrode geometry can have even more significant impact on electrode performance than having a larger perimeter for a given surface area.
