Local control of magnetic objects in microfluidic channels
Microfluidics and Nanofluidics - Tập 8 - Trang 123-130 - 2009
The application of magnetic fields in microfluidics is of growing interest and the localisation of the applied field emerges as a key requisite for future integration with other micro-platforms. In this paper, we present a novel strategy of fabrication of an integrated microchannel, which combines the advantages of localisation of the magnetic field with simplicity of design and fabrication. The c......
On the methodologies for the assessment of the impact of parameters in acoustophoretic separation devices
Microfluidics and Nanofluidics - Tập 23 - Trang 1-8 - 2019
In this communication, we reconcile the kinematic method illustrated by some authors (Yang et al. in Microfluid Nanofluid 22:44–56, 2018; Vitali et al. in RSC Adv 8:38955, 2018) in studying the impact of system and suspension parameters on acoustophoretic separations with the statistical method formerly proposed by Garofalo (Microfluid Nanofluid 18(3):367–382, 2014a; ASME 2014 3rd global congress ......
Isothermal titration calorimetry in a polymeric microdevice
Microfluidics and Nanofluidics - Tập 21 - Trang 1-9 - 2017
Microelectromechanical systems (MEMS) technology can enable the integration of isothermal titration calorimetry (ITC) on a single chip for direct thermodynamic characterization. However, existing ITC microdevices either do not yet allow proper control of reaction conditions for thermodynamic characterization of biomolecular reaction systems or do not yet suitable for practical applications because......
Design rules for microscale capillary phase separators
Microfluidics and Nanofluidics - Tập 21 - Trang 1-16 - 2017
We propose a model to compute operating boundaries for on-chip continuous-phase separation of slug flow using capillary separators, verified by an extensive experimental study. The operating region of the device is described by two limits, defining the range of pressure drop across the separator at which full withdrawal of the continuous phase through the capillaries takes place while simultaneous......
Experimental study of the separation behavior of nanoparticles in micro- and nanochannels
Microfluidics and Nanofluidics - Tập 10 - Trang 69-80 - 2010
In this article, we investigate the effects of pH, ionic strength, and channel height on the mobility and diffusivity of charged spherical particles within planar microfluidic channels. Specifically, we report results of a broad experimental study on the transport and separation behavior of 50 and 100 nm spherical carboxylated polystyrene nanoparticles, confined in 20 μm, 1 μm, and 250 nm deep flu......
Development of micro-vibrating flow pumps using MEMS technologies
Microfluidics and Nanofluidics - Tập 13 Số 5 - Trang 703-713 - 2012
Lattice Boltzmann simulations in microfluidics: probing the no-slip boundary condition in hydrophobic, rough, and surface nanobubble laden microchannels
Microfluidics and Nanofluidics - Tập 8 - Trang 1-10 - 2009
In this contribution, we review recent efforts on investigations of the effect of (apparent) boundary slip by utilizing lattice Boltzmann simulations. We demonstrate the applicability of the method to treat fundamental questions in microfluidics by investigating fluid flow in hydrophobic and rough microchannels as well as over surfaces covered by nano- or microscale gas bubbles.
In situ colorimetric detection and mixing of glucose–enzyme droplets in an open-surface platform via Marangoni effect
Microfluidics and Nanofluidics - Tập 20 Số 7 - 2016
Rotary polymer micromachines: in situ fabrication of microgear components in microchannels
Microfluidics and Nanofluidics - Tập 19 Số 1 - Trang 67-74 - 2015
Quantitative comparison of thermal and solutal transport in a T-mixer by FLIM and CFD
Microfluidics and Nanofluidics - Tập 5 - Trang 603-617 - 2008
The development and adoption of lab-on-a-chip and micro-TAS (total analysis system) techniques requires not only the solving of design and manufacturing issues, but also the introduction of reliable and quantitative methods of analysis. In this work, two complementary tools are applied to the study of thermal and solutal transport in liquids. The experimental determination of the concentration of ......
