Terahertz time-domain attenuated total reflection spectroscopy, in combination with a two-interface model, is used to determine the complex dielectric constants of cultured human cancer cells (DLD-1, HEK293 and HeLa). Picosecond sub-picosecond water dynamics are dominant measured these cells. We demonstrate that responses below 1.0 THz best characterize particular when compared extracellular water. Debye-Lorentz fitting revealed this due significantly slow relaxation mode enhanced fast These...
Recent studies of saccharides’ peculiar anti-freezing and anti-dehydration properties point to a close association with their strong hydration capability destructuring effect on the hydrogen bond (HB) network bulk water. The underlying mechanisms are, however, not well understood. In this respect, examination complex dielectric constants saccharide aqueous solutions, especially over broadband frequency region, should provide interesting insights into these properties, since responses reflect...
To produce high-quality citrus, the harvest time of citrus should be determined by considering its maturity. evaluate maturity, Brix/acid ratio, which is ratio sugar content or soluble solids to acid content, one most commonly used indicators fruit estimate fluorescence spectroscopy, a rapid, sensitive, and cheap technique, was adopted. Each peel extracted, value measured. Then, fluorescent spectrum analyzed using convolutional neural network (CNN). In matrix called excitation emission (EEM)...
Harvesting cherry tomatoes is more laborious than harvesting larger size because of the high fruit density in every cluster. To save labor costs, robotic has been studied Japan. An effective vision algorithm, to detect positions many small fruits, was developed for guidance robotically harvested tomatoes. A spectral reflectance visible region identified and extracted provide contrast images cluster identification. The 3-D position each determined using a binocular stereo technique. robot one...
Aqueous solutions of poly(N-isopropylacrylamide), P-NIPAAm, exhibit a noticeable temperature responsive change in molecular conformation at cloud point (Tcp). As the rises above Tcp, extended coil-like P-NIPAAm structure changes into swollen globule-like as hydration levels decrease and hydrophobic interactions increase. Though water plays an important role this coil-to-globule transition behavior molecules associated hydrogen-bond (HB) network surrounding bulk are still veiled uncertainty....
The hydration state in living cells is believed to be associated with various cellular activities. Nevertheless, vivo characterization of intracellular under physiological condition has not been well documented date. In this study, the an intact HeLa cell monolayer was investigated by terahertz time-domain attenuated total reflection spectroscopy. Combined extended theory Onsager, we found 23.8 ± 7.4% water hydrated biomolecules (corresponding 1.25 g H2O/g solute); exhibiting slower...
