A phantom study of terahertz spectroscopy and imaging of micro- and nano-diamonds and nano-onions as contrast agents for breast cancer

Bowman, Tyler, Alec Walter, Olga Shenderova, Nicholas Nunn, Gary E. McGuire, and Magda El-Shenawee.  Biomedical Physics & Engineering Express (2017).

Abstract

Terahertz (THz) imaging is effective in distinguishing between cancerous, healthy, and fatty tissues in breast tumors, but a challenge remains in the contrast between cancerous and fibroglandular (healthy) tissues. This work investigates carbon-based nanoparticles as potential contrast agents for THz imaging of breast cancer. Microdiamonds, nanodiamonds (NDs), and nanometer-scale onion-like carbon (OLC) are characterized with THz transmission spectroscopy in low-absorption backgrounds of polydimethylsiloxane or polyethylene. The refractive index and absorption coefficients are calculated based on the measured electric fields. NDs show little effect on the THz signal, microdiamonds express resonance-like, size-dependent absorption peaks, and OLC provides a uniform increase in the optical properties even at low concentration. Due to its strong interaction with THz frequencies and ability to be activated for selective binding to cancer cells, OLC is implemented into engineered three-dimensional breast tumor models composed of phantom tissue mimicking infiltrating ductal carcinoma surrounded by a phantom mimicking healthy fibroglandular tissue. This model is imaged using the THz reflection mode to examine the effectiveness of contrast agents for differentiation between the two tissue types. In both spectroscopy and imaging, a 10% concentration of OLC shows the strongest impact on the THz signal and holds promise as a THz contrast agent.

Terahertz Imaging and Electromagnetic Model of Axon Demyelination in Alzheimer's Disease

Yeo, Woon-Gi, Ogan Gurel, Nandhini Srinivasan, Paul D. King, Niru K. Nahar, Sungchan Park, Norman L. Lehman, and Kubilay Sertel. " IEEE Transactions on Terahertz Science and Technology (2017)


Abstract:

We investigate the utility of terahertz (THz) spectroscopy in identifying Alzheimer's disease in human brain tissue. Using reflection-mode time-domain THz spectroscopy, two-dimensional images of formalin-fixed and paraffin-embedded tissue samples of the hippocampus area were recorded in the 60 GHz–2 THz band. The THz images were compared with microscopic images of the same samples after hematoxylin and eosin staining. We demonstrate that the THz reflection spectra, particularly from white matter, reveal detectable differences between postmortem brain tissues exhibiting Alzheimer's disease and normal controls. The THz reflectivity of white matter areas was on average 4.2% higher than that of gray matter regions in tissue samples with known Alzheimer's history, whereas for normal control samples the contrast was only 2%. Additional studies further enhance this hypothesis, and the demyelination of white matter in Alzheimer's tissues suggests a possible cause for the differences in the THz reflection spectra. We also compare the THz response of the tissues with conventional Luxol-fast blue staining to demonstrate the correlation between the two methods for predicting demyelination. In addition, we present a simplified electromagnetic model of white matter axons exhibiting various degrees of demyelination to further support this hypothesis through full-wave electromagnetic simulations. This study offers, for the first time, proof of concept for the feasibility of detecting Alzheimer's disease using THz spectroscopy on ex vivo samples.
