2:15 pm 2:15 pm : Millimeter Wave And Terahertz Dielectric Waveguide Microfluidic Sensors
Presenter: Premjeet Chahal

This paper reports the design, fabrication, and characterization of a suite of dielectric probes for near-field and evanescent microfluidic sensing applications. Four different probe designs are studied. These structures are made from cylindrical alumina dielectric rods, and were integrated with microfluidic channels. Mixtures of two different solvents were used to characterize the probes. The sensitivity of the probes is measured under a continuous flow of liquids in the microfluidic channel. In comparison to evanescent wave probes, an improvement of up to 25X in sensitivity is obtained using the new probes.

2:30 pm 2:30 pm : Effects Of THz Radiation On Human Fibroblasts In-vitro: Exposure Set-up And Biological End Points
Presenter: Gian Piero Gallerano

In vitro exposures of human fibroblasts have been performed in a wide band between 100 and 150 GHz using the ENEA Compact Free Electron Laser. The methodology of the study and the exposure set-up will be presented together with an analysis of preliminary results.

2:45 pm 2:45 pm : Millimetre-wave Dielectric Spectroscopy For Cell Analysis
Presenter: Helena Rodilla

A millimeter-wave sensor based on a CPW line has been designed and fabricated as a first prototype for impedance spectroscopy to be combined with a multifunctional micropipette for cell and membrane analysis. The first mm-wave measurement results show the sensitivity of the layout by distinguishing the cells from the media and monitoring the attachment process of the cells to the sensor surface. Measurements were performed on umbilical cord stem cells and cartilage thumb cells.

3:00 pm 3:00 pm : Exploration Of Wound Physiology Using THz Imaging
Presenter: Zachary Taylor

A THz imaging system was used to assess the effect of tissue water content following the injection of histamines in in vivo rat models. Histamines are released by the body following and injury and are known to contribute to the buildup, organization, and dissipation of edema. A rat was anesthetized and then injected with a 100 microliter solution of histamine. Significant changes in tissue water content were observed. Tissue water content contrast generated by THz imaging may be a useful tool in research of wound response due to the lack of medical imaging systems that are sensitive to surface tissue water content.
