Analysis of electroosmotic flow of power-law fluids in a slit microchannel
TL;DR: Calculations are performed to examine the effects of kappaH, flow behavior index, double layer thickness, and applied electric field on the shear stress, dynamic viscosity, velocity distribution, and average velocity/flow rate of the electroosmotic flow of power-law fluids.
Journal ArticleDOI
Electroosmotically driven capillary transport of typical non-Newtonian biofluids in rectangular microchannels.
TL;DR: A detailed theoretical model is developed for studying the capillary filling dynamics of a non-Newtonian power-law obeying fluid in a microchannel subject to electrokinetic effects, and flow characteristics depicting advancement of the fluid within the microfluidic channel turn out to be typically non-linear.
Journal ArticleDOI
Analytical solution of mixed electro-osmotic/pressure driven flows of viscoelastic fluids in microchannels
TL;DR: In this article, the authors presented analytical solutions for the flow of viscoelastic fluids in micron sized ducts under the combined influence of electrokinetic and pressure forces using the Debye-Huckel approximation, including the limit case of pure electro-osmotic flow.

On the nanofluids applications in microchannels: A comprehensive review
TL;DR: A comprehensive assessment of nanofluids' applications in various microchannel geometries and shows ever-increasing importance of nan ofluids applications in microchannels.
Journal ArticleDOI
Electrokinetic flow of non-Newtonian fluids in microchannels.
TL;DR: A generalized form of the force-flux relations is proposed, which is of interest in microfluidic applications and allows one to predict the flow rate and electric current as functions of the simultaneously applied electric potential and pressure gradients.

Rapid determination of single base mismatch mutations in DNA hybrids by direct electric field control
TL;DR: It is demonstrated that controlled electric fields can be used to regulate transport, concentration, hybridization, and denaturation of single- and double-stranded oligonucleotides and single base pair mismatch discrimination is carried out rapidly and with high resolution.

The Fahraeus effect.
James H. Barbee,Giles R. Cokelet +1 more
TL;DR: The results support the contentions that flow conditions upstream from the capillary entrance are not responsible for the Fahraeus effect, and that the hematocrit in the capillaries is a function of radial position.
Journal ArticleDOI
Modeling of DNA hybridization kinetics for spatially resolved biochips
TL;DR: This work proposes a general kinetic model of heterogeneous hybridization and develops a technique for estimating the kinetic coefficients for the case of well-spaced, noninteracting surface-bound probes and shows how the dynamic transport of the targets is likely to affect the rate and location of hybridization.

Keisuke Horiuchi,Prashanta Dutta +1 more
TL;DR: In this article, a separation of variables technique is applied to obtain analytical solutions of temperature distributions from the energy equation of electroosmotically driven flows, and the thermal analysis considers interaction among inertial, diffusive and Joule heating terms in order to obtain thermally developing behavior of steady electroosmotic flows.

Blood viscosity and blood pressure: role of temperature and hyperglycemia.
TL;DR: Temperature, glucose and viscosity levels of blood are important factors for BP and, in this state, blood flow rate decrease was 20% and BP increase for physiological compensation was 25%.
