Abstract
The primary research objetive of this project is to explore the use of nanoelectrochemical sensors to study single cells and single nanoparticles. The proposed scientific activity will focus on: 1) the application of nanoelectrodes to get information on reactive oxygen/nitrogen species and thioredoxin proteins in macrophages after an inflammatory activation; 2) scanning electrochemical microscopy (SECM) studies to investigate the role of mitochondria on the respiration process; 3) a study of oxygen adsorption on single nanoparticles grown on nanoelectrodes; 4) a study of oxygen reduction on single nanoparticles grown on nanoelectrodes. In addition, the project includes the organization of a two-day international workshop on nanoelectrodes and we will seek the financial support of sponsors. The proposal is led by two investigators with established track records in electroanalytical chemistry, microelectrochemistry and scanning electrochemical microscopy. (AU)
