Dr. Mohd KHAIRUDDIN MD ARSHAD : Nanoscaled Devices & Materials: Application in Label-Free Biosensors

Résumé :
Field-Effect-Transistor (FET) is a leading technology for successful today’s electronic gadgets since the birth of the first transistor more than 70 years ago. Today, the application of FET is more diversified, inclusive in biosensor applications i.e. the ability to convert biomolecules interaction into a measurable electrical signal. Compatible with existing silicon technologies, higher sensitivity, higher surface-to-volume (integration with 0D, 1D and 2D materials), label-free, ambipolar conduction, and ease of modification of its intrinsic properties are the exceptional characteristics of biosensors-based FET.. In this presentation, the chronological aspect of device scaling from the conventional scaling approach to the fully-depletion concept, which emerges from the beauty of thin-body silicon-on-insulator technology. Finally, the application of biosensors-based FET with advantages and strategies for enhancement, particularly integration with nano-scale materials and substrate-gated, which increase the surface-to-volume and better control of charge conduction is demonstrated.
