The electric field component of the microwaves emanating from the dielectric resonator is able to penetrate the microfluidic channel, serum, and individual blood cells. Subsequently, it interacts with every hemoglobin molecule present within each red blood cell. On page 536 , Toby H. Basey-Fisher and team conclude that the dielectric contrast between water and hemoglobin means that a change in the hemoglobin concentration leads to a change in the microwave response.

Bio-sensing by electromagnetic waves from GHz towards THz frequencies, although not yet established as a common method for biomedical applications, offers challenging opportunities, which are complementary to the established optical methods, often based on plasmonic waves and resonances. The longer wavelength - in comparison to visible and IR provides a disadvantage in terms of the smallest possible interaction volume, which can be partially overcome by evanescent field methods. However, the high absorption of micro- and millimetre waves by liquid water, which is the most abundant component of biological substances, provides a unique observation window, which is substantially different and therefore complementary to the other parts of the electromagnetic spectrum. © 2013 IEEE.

An Otto prism coupling setup with a spoof plasmon surface underneath is the centerpiece of work by S. A. Maier and co-workers, in which terahertz liquid sensing with figures-of-merit as high as 49 are demonstrated. On page 543, water molecules are shown to go onto the spoof plasmon surface, which consists of linear arrays of subwavelength grooves, tightly confining the spoof plasmons. The plasmons are sensitive to the refractive index of the dielectric filling the grooves, and phase jumps at spoof plasmon resonances provide the readout response. © 2013 WILEY-VCH Verlag GmbH & Co.
