Subterahertz characterization of ethanol hydration layers by microfluidic system

Abstract

Characterizations of ethanol hydration layers are examined through subterahertz spectroscopy of water/ethanol mixtures by using a microfluidic system. A three-component model is used to explain measurements discrepancies with the Lambert–Beer law and to determine ethanol hydration shell absorption. Moreover, the hydration shell distribution is compared with molecular dynamics simulations with a good agreement. Ethanol hydration number is then computed and it can quickly characterize only the first water hydration layer or the whole hydration shell, depending on the chosen extraction model.

Physique des fluides aux échelles microscopiques pour l’ingénierie des microsystèmes : l’apprentissage par la simulation

“…Une perspective prometteuse de ces microsystèmes est leur application à l'analyse biologique [4]. Une part importante de la recherche est actuellement consacrée aux "Laboratoires sur Puce", dont l'objectif est l'intégration de l'analyse de fluides biologiques.…”

Terahertz Spiral Planar Goubau Line Rejectors for Biological Characterization

“…More recently THz-instrumentation improvements lead to measurements on liquid-solutions and show abilities to characterize protein conformation states. This is why we couple micronanotechnology and THz spectroscopy with the use of waveguides inside microfluidic circuits [6,8]. Figure 13.…”

“…Nevertheless, by increasing the frequency range up to the THz spectrum, waves/photon energy reaches biological weak bonds energy, massively represented in liquids. Consequently, THz frequencies bring information concerning radicals, biomolecules but also concerning conformational states of proteins [5,6]. Today, lot of biological studies concern protein-protein or protein-cell real-time interactions [7,8].…”

Development of planar Goubau line - microfluidic integrated devices for THz spectroscopy of liquid analytes

“…Two types of transmission line have been used for on-chip microfluidic spectroscopy in the frequency range of interest; microstrip lines (MSLs) [2] and planar Goubau lines (PGLs) [3], although coplanar waveguide has also been used at lower (GHz range) frequencies [4]. In previous PGL work [3], microfluidic channels were overlaid perpendicular to a single-wire transmission line, and a vector network analyser (VNA) used to excite the probing electric field.…”

“…In previous PGL work [3], microfluidic channels were overlaid perpendicular to a single-wire transmission line, and a vector network analyser (VNA) used to excite the probing electric field. While this geometry allows information about the liquid under test (LUT) to be extracted, here we demonstrate that the reflections resulting from an overlaid microfluidic channel limit the range of solutions that can be analysed in such a system.…”
