EM-Wave Biosensors: A Review of RF, Microwave, mm-Wave and Optical Sensing

Guided-Wave Optical Biosensors

Guided-wave optical biosensors are reviewed in this paper. Advantages related to optical technologies are presented and integrated architectures are investigated in detail. Main classes of bio receptors and the most attractive optical transduction mechanisms are discussed. The possibility to use Mach-Zehnder and Young interferometers, microdisk and microring resonators, surface plasmon resonanc...

Love Wave Biosensors: A Review

WBG devices for microwave mm-wave circuit

Future smart systems for communication and RF-sensing will have to achieve autonomous and self-reconfigurable operations, for real-time and efficient selfoptimization of their performance. The needs for such reconfigurable systems are not only to overcome the design tradeoffs that current analogue components must endure, but also to realize new and more efficient systems with improved functiona...

Surface acoustic wave biosensors: a review.

This review presents an overview of 20 years of worldwide development in the field of biosensors based on special types of surface acoustic wave (SAW) devices that permit the highly sensitive detection of biorelevant molecules in liquid media (such as water or aqueous buffer solutions). 1987 saw the first approaches, which used either horizontally polarized shear waves (HPSW) in a delay line co...

Microwave and terahertz wave sensing with metamaterials.

We have designed, fabricated, and characterized metamaterial enhanced bimaterial cantilever pixels for far-infrared detection. Local heating due to absorption from split ring resonators (SRRs) incorporated directly onto the cantilever pixels leads to mechanical deflection which is readily detected with visible light. Highly responsive pixels have been fabricated for detection at 95 GHz and 693 ...
