Research in the EAC Lab

In the lab we use various processes for our conducting polymer depositions.

The main technique is electrodeposition since it provides well adherent coatings with excellent properties for charge transfer over the solid-liquid boundary. Hence, the coated microelectrode obtains very low impedance in comparison to the bare metallic surface.

Furthermore, electrochemically driven deposition is limited to the conducting surfaces of the probe. Thus, such coatings can be applied subsequent to the final step of the probe microfabrication and there is no need for additional patterning.

In addition, we employ polymerization techniques such as vapor phase polymerization (VPP) for efficiently coating larger non-conducting substrates. Furthermore, casting of various PEDOT dispersion are used for rapid production of thick coatings.

Various electrochemical standard techniques are used to characterize the performance of our microelectrode coatings, thereamong:

  • Electrochemical impedance spectroscopy (EIS) 
  • Stress/stability testing via bi-phasic pulsing Cyclic voltammetry

Drug release is analyzed using

  • High Performance Liquid Chromatography (HPLC) 
  • Electrochemical Quartz Crystal Microbalance (EQCM) analysis 
  • Fluorometry

Morphology is analyzed using

  • SEM.
     

Although we have nothing specific listed at the moment you can always l send us your application for a M.Sc. project.
