Prof. Bard is considered a "father of modern electrochemistry" for his innovative work developing the scanning electrochemical microscope, his co-discovery of electrochemiluminescence, his key contributions to photo electrochemistry of semiconductor electrodes. Prof. Bard changed our understanding of the chemistry and physics of individual molecules. He pioneered the development of the scanning electrochemical microscope, allowing high resolution chemical imaging of surfaces and the study of chemical reactions at the nanoscopic regime, applied to biological and catalysis systems. Scanning electrochemical microscopes are used worldwide in investigations of electro-catalytic mechanisms, in identification of cancerous cells, in mapping transport paths in the skin for trans-dermal drug delivery, and for lithographic patterning of surfaces. His efforts are largely responsible for the development of electrochemically generated electroluminescence reactions, and immunoassay commercial technology, used worldwide in medical diagnosis and research. Bard and his team were the first to investigate the electrochemistry of particle semiconductors, for solar energy conversion and environmental remediation. Thus, Prof. Bard’s contributions to science, through his investigation of fundamental molecular electrochemistry and the development of electro-analytical methods, have truly served mankind, in medical, energy, and materials technologies.
