Dendritic Gold Nanoparticles Towards Transparent and Electroactive Electrodes

Abstract: The combination of UV-visible absorption and electrochemical experiments (spectroelectrochemistry) enables to obtain highly specific spectroscopic information (in situ and operando) from modified surfaces. However, such application can be limited by the self-absorbance, for example, when metallic nanoparticles are present on modified surfaces. Indium-tin oxide onto glass (ITO) is a typical electrode commonly used for spectroelectrochemistry; ITO is an oxide-based semiconductor, and in numerous applications it is necessary to promote the modification of the electrode surface without s...
