Biosensors can be generated with materials capable of detecting analytes such as Dopamine, Glucose or DNA by utilizing their electrochemical properties and interactions with specific analytes. The substrate materials can typically be gold, silicon or Indium Tin Oxide (ITO) coated glass. These substrates are modified with palladium to explore their unique electrochemical properties. Our current research is focusing on the detection of Dopamine under the presence of various precursor and structurally similar molecules such as L-DOPA, Tyrosine, and Norepinephrine using two-dimensional assemblies of palladium nanoparticles. We have utilized a number of detection and characterization methods such as cyclic voltammetry, electrochemical impedance spectroscopy, zeta potential, UV-vis spectroscopy and atomic force microscopy (AFM) to understand the morphology of the nano-sized substrate surfaces and also determine the functionality of the surface as Dopamine Biosensor.<br/>
