Titre : Nanotechnology-boosted sensors: principles for chemical and biomedical sensing
Institut Néel, Salle D420 (Nevill Mott)
Résumé : Nanotechnology is key in the development of miniaturised (nano)sensors, allowing the exploitation of new or the improvement of existing sensing mechanisms not attainable or beyond those used in microtechnology. This is evidenced by the large number of nanosensors which have been developed and marketed in the last 20 years.
In this talk I will present three examples of (nano)sensing principles and the devices we are developing or under development thereof that illustrate improvements and new sensing mechanisms. These mechanisms and their applications are: chemoresistive gas sensors based on nanowires, gas and liquid sensors based on plasmon resonant techniques and nanophotonic stress sensors based on silicon nanopillars.
