Résumé : The development of sensors for detection of biomolecules and pollutants with high accuracy, and reproducibility is a key research challenge. The electrochemical approach using nanomaterials is one of the most promising candidate technologies to meet this challenge due to its simplicity, high sensitivity and selectivity. Indeed, because of their nanometer size, high aspect ratio and especially high surface area to volume ratio, the nanomaterials can enhance the active surface area and the electron transfer for the sensors. This is what makes them very attractive and have expanded the possibilities of electrochemistry based sensor development.

In this talk, benefits of nanomaterials for electrochemical sensors and biosensors will be discussed. The purposes of development are focus on the area of environmental and clinical applications i.e., glucose and tumor marker biosensor, endocrine disruptors pesticides and herbicides sensor. The development of micro-biosensor for measuring metabolite and biomarker on the single living cell will be also presented. Finally the talk will discuss the current challenges and give perspectives on the future in this rapidly developing area.

Dr. Sujittra Poorahong received her B.Sc. degree in Chemistry with the second honors from Prince of Songkla University, Thailand in 2006. She got her M.Sc. and Ph.D. in Analytical Chemistry from the same University in 2008 and 2012, respectively. Her Ph.D. research was funded by The Royal Golden Jubilee Ph.D. Program, the Thailand Research Fund, focused on the development of analytical techniques based on nanomaterials. During her Ph.D., she received many awards from national and international agencies, such as Young Chemist Award from the Royal Society of Chemistry Advances in 2011 and Honorable mention awards for Ph.D. Thesis in 2014. In July 2014 she joined the Department of Computer Science at the University of Quebec at Montreal, Canada, where she is currently working as postdoctoral researcher. Her research interests include biosensors and chemical sensors using nanomaterials for medical, environmental and industrial applications.
