报告摘要：
Exploiting the chemical (surface) sensitivity of nanomaterials that can be transformed into electrical signals, integrated and comprehensive nano-electronic signaling approaches have been employed as new tools for the application in chemical sensing, and further for the fundamental study of chemical and biological systems. In specific, we have developed a novel on-chip characterization strategy, electrical transport spectroscopy (ETS), as an alternative to the traditional spectroscopic characterization techniques, for in situ electrochemical surface monitoring with high surface sensitivity and surface specificity. Primary ETS investigations have provided mechanistic insights into various platinum-based electrocatalytic reactions, and further revealed the competitive anionic adsorption behavior (with oxygenated species) and their correlations to the electrokinetics of oxygen reduction reaction (ORR), which opens an efficient pathway to address the practical poisoning issue (at trace level contaminations) from a fundamental perspective. Additionally, ETS has also been applied to reveal the charge transport mechanism and the electrochemical behavior in electrogenic microbes, which has been a subject of on-going debate.
