Presenting Analytical Performances of Chemical and Biological Sensors: Experience Feedback

The analytical performances of each novel chemical or biological sensor permit the evaluation of its accuracy, relevance and mainly potential use in real samples. The most frequently reported parameters in the sensors domain are sensitivity, the limit of detection, linear range, selectivity, affinity and recovery. However, and despite the fact that these parameters are well defined in international standards, most teams working in the field of sensors "adjust" these concepts to their experimental results, which sometimes makes it difficult to compare experimental results from different studies. Some suggestions will be done in this experience feedback to help scholars and young researchers to adopt a coherent approach and to take the necessary step back for better interpretation of the analytical performances of their designed sensors. Without forgetting of course the problem of how to get rid of non-specific adsorption.

Short biography:

Dr. Najla Fourati obtained her PhD in Materials Science at the Conservatoire National des Arts et Métiers (Cnam-Paris) in 1999. She joined the Cnam Laboratory of Physics in Paris in 2002 and the SATIE Laboratory in 2014. She is Assistant Professor at Cnam Paris from 2008. Her research concerns the development and realization of surface acoustic wave (SAW) and electrochemical sensors for chemical and biological applications. Most of her current work is devoted to the design of ionic and molecular imprinted polymers-based sensors. The detected analytes are as varied as proteins, pesticides, heavy metal ions … She uses AFM to monitor changes in materials surfaces during the functionalization steps.
