چکیده

We demonstrate a millimeter-wave sensing method based on a coplanar waveguide for biological membrane studies in an open-volume fluidic arrangement. On-wafer measurements of scattering parameters were performed up to 110 GHz. The sensor shows the ability to distinguish the addition of 20% cholesterol in artificial biological membranes, which is an important component influencing the stability and fluidity of such systems. This is the first stage in the development of a millimeter-wave sensor for biological model membrane studies.

Millimeter-wave sensor based on a λ/2-line resonator for identification and dielectric characterization of non-ionic surfactants

Studies of biological and artificial membrane systems, such as niosomes, currently rely on the use of fluorescent tags, which can influence the system under investigation. For this reason, the development of label-free, non-invasive detection techniques is of great interest. We demonstrate an open-volume label-free millimeter-wave sensing platform based on a coplanar waveguide, developed for id...
