Thermal Management Using Liquid-vapor Phase Change in Nanochannels
… in ∼728 nm height cross-connected buried SiO2 nanochannels, with micropores of diameter ∼2 μm at each intersection, is accomplished. The micropores allow water from a droplet placed on the surface to wick into the channels as well as allow thin-film evaporation from a meniscus. Experimental …

EXPERIMENTAL CHARACTERIZATION AND MODELING OF ASPECT-RATIO-DEPENDENT DIFFUSION OF NANOCRYSTALS IN NANOCHANNELS
… of semiconductor nanocrystals in rectangular nanochannels has been undertaken. The nanocrystals are terminated with hydrocarbon ligands and suspended in toluene, considered an aprotic solvent. Time-dependent concentration profiles are measured as a function of distance from the channel …

Ultra-high-aspect-ratio nanofluidic channels for high-throughput biological applications
… nanofluidic channels, such as planar nanochannels and square nanochannels, suffer from small open volume and, as a result, low sample throughput, compared to microchips and conventional gel-based systems. For practical and wider applications of artificial nanochannels, it is of crucial …

Development of an Enzyme-Linked ImmunoSorbent Assay (ELISA) with Enhanced Sensitivity in a Nanofluidic System
… that antibody-antigen binding constants in nanochannels were similar to experiments performed in microtiter plates at low antigen concentrations; however the bound fraction in nanochannels at high antigen concentration decreased due to steric hindrance. Binding kinetics in nanochannels was …

Gate potential control of nanofluidic devices
… gate potential control on the nanofluidic nanochannels was experimentally investigated in this work. Like in the field effect transistors (FET) in microelectronics, molecular transport in micro/nanofluidic channels can be controlled by applying external potentials on the wall of the fluidic …

Continuum and Atomistic Simulation of Electrically-Mediated Flow Through Nanometer Channels
… profiles and other fluid characteristics in nanochannels. As the continuum theories based on the Poisson-Boltzmann and the Navier-Stokes equations account for the various intermolecular interactions in a mean-field fashion, they fail to predict the fluid/ion characteristics accurately. In …

Design, Fabrication, Testing of CNT Based ISFET and Characterization of Nano/Bio Materials Using AFM
… is investigated and used for creating nanochannels on silicon surfaces. Since AFM based nanomanipulation and nanomachining is highly controllable, nanochannels are precisely scratched in the area between the source and drain of the FET where the inversion layer is after the ISFET is …

Polymer Micro- and Nanofluidic Systems for In Vitro Diagnostics: Analyzing Single Cells and Molecules
… surface modification of polymer nanoslits and nanochannels for the assessment of the associated electrokinetic parameters – surface charge density, zeta potential and electroosmotic flow. This study provided information on possible routes that can be adopted to engineer proper wall chemistry of …

Layer-by-layer assembly in confined geometries
… deposition results in systematic bridging of the nanochannels with a nanoporous multilayer. This fundamental knowledge was applied to the systematic narrowing of nanochannels embedded in a hybrid micro/nanofluidic device using LbL assembly of polyelectrolytes. The narrowing of these channels was …

Investigation of Two-Dimensional Structured Polyaniline for Supercapacitor Applications
… materials featuring well-organized flat nanochannels, as well as adjustable structural and chemical properties have emerged as promising candidates for energy storage, and more importantly, established a perfect platform for ion transport study. The anion-dominated behaviour, which is …
