Abstract:

Considering this toxicity potential of peroxynitrite formation in meat with impact for food safety, it is proposed herein to develop advanced tools to quantify the presence of peroxynitrite in food: meat, in real-time in situ. While there are several detection methodsavailable for peroxynitrite (e.g. oxidation of fluorescent probes, EPR spectroscopy, probe nitration, chemiluminescence, immun-histochemistry) these tend to be more elaborate and difficult to apply for real-time quantification, due to their inherent complexity. The electrochemical detection of peroxynitrite would be a simpler and more convenient technique.
Based on initial results and specific knowhow, the team final goals are to develop electrochemical ONOO- sensitive in situ methods, based on new/improved (metalloporphyrins and conjugated polymers) nanocomposies, for detection its dynamics in foods such as meat-fish tissue and use the results to better understand ONOO− implications for food quality and safety. Once perfected as analytical tools, the peroxynitrite microprobes could be studied for possible use in pharmacology and toxicology.
