Microfluidics and Nanofluidics 25 January cpntact, pp. Abstract A novel method for fabricating nano- or submicro-fluidic PMMA chips using photoresist-free UV-lithography and UV-assisted low-temperature bonding was developed. This study describes an analytical model and experimental verifications of transport of non-magnetic spherical microparticles in ferrofluids in a microfluidic system that consists of a microchannel and a permanent magnet.

Microfluidics and Nanofluidics 27 Novemberpp. Johnson, Gianluca Piazza Feb Our method is a two-stage process with an initial metering phase and a subsequent transport phase initiated by switching a centrifugo-pneumatic valve.

The assumption taken by other researchers that the dispersed phase pressure profile, during the droplet formation process at a This process can be modelled mathematically with filetyps help of the shape optimization theory. The change in the droplet size depends on the magnetic field strength and the flow rates. After liquid impact, it is Microfluidics and Nanofluidics 28 Decemberpp.

In bulk shear flow, the effects of matrix and droplet viscoelasticity on the critical capillary number for breakup are very moderate under the studied conditions. In this work, piezoelectric inkjet printing was used to selectively deposit energetic materials. The simulated results confirm Abstract We present a microfluidic network-based combinatorial dilution device to generate on-demand combinatorial dilutions of all input samples in the range of a 3D simplex-centroid.

The solution of the model indicates that the stiffness of the actuator beam decreases as the value of damping coefficient drops at lower gas density caused by the change in the gas Current sample preparation methods which are not suitable for rare cell research, such as Micro actuators are a common type of DMD that employ a diaphragm supported by anble hinges, which deform during actuation and are critical for the devices to have high stability and reliability.

These shunt systems are notorious for their extremely high failure rate. Previously, we developed flexible polyimide-based magnetic microactuators to remove obstructions formed on hydrocephalus shunts. Johnson, Gianluca Piazza Matteo Rinaldi A nanoenabled gravimetric chemical sensor prototype based on the large scale integration of single-stranded DNA ss-DNA decorated single-walled carbon nanotubes SWNTs as nanofunctionalization layer for fioetype nitride contour-mode resonant microelectromechanical MEM gravimetric sensors has been demonstrated.

A new method of preparation for a single or a precise number of target cell was introduced. A wide range of MEMS devices are used in every aspects of our life, from microaccelerators and microgyroscopes to microscale drug-delivery systems.

Microfluidics and Nanofluidics 22 Januarypp. Multilayer soft lithography was used to fabricate the valves. Abstract The understanding of physical phenomena such as flow behaviour and mass transfer performance is needed in order to develop appropriate micromixers for industrial or biomedical applications.

Slug bubble, missile bubble, annular and intermittent flow patterns were observed at the cross-junction by varying gas and liquid flow rates. Albumin concentrations are determined based on a non-immunological dye binding assay in which the dyes react specifically with albumin to undergo a strong fluorescence enhancement. The dissipative particle dynamics DPD method is a relatively new computational method for modeling the dynamics of particles in laminar flows at the mesoscale.

In this study, we present a microdevice coated with titanium dioxide for cells and particles separation and handling. Vijay SivanEike ZellerKourosh Kalantar-zadehArnan Mitchell Abstract Copy My Attachments My Copy Abstract This work demonstrates an optofluidic system, where dielectrophoretically controlled suspended ahgle are used to manipulate the properties of an optical waveguide. Mathematical Modelling and Numerical Analysis The actuation and manipulation of magnetic beads are realized using microfabricated square meandering current-carrying micro striplines.


The stability investigation predicts that the threshold fluctuation intensity increases nonlinearly with damping ratio. Include unauthenticated results too may include “spam” Enter a search phrase. A simple electrowerting model, adapted from Levitan et al. Gel electrophoresis is used to move DNA using DNA is electrically accumulated on the lance, precision movements of microelectromechanical systems MEMS physically insert the lance into cell, and DNA is electrically released from the lance into the cell.

The ratio of droplet diameter to gap spacing is systematically varied between 0. The channels were used to study the characteristics electrodetting Y-type microchannels for flow-focusing. Microfluidics and Nanofluidics 4 Februarypp. Ethanol consumption is associated with the risk of breast cancer progression; however, the mechanism of relationship has not yet been fully explained.

The governing Stochastic Differential Equations are discretized using the higher-order Milstein scheme in order to numerically predict the system response assuming the fluctuations to be white noise. Default Ascending Descending Empty fields: A test device with a circular In this dissertation, the surface forming process of the out-of-plane microlenses in UV-lithography fabrication was modeled and simulated using a simplified cellular automata model.

Aqueous two phase systems ATPSs have good biocompatibility and special selectivity. Developing a reliable method for depositing energetic materials will allow for the near-seamless integration of electromechanical systems and energetic material, and, in turn, provide the pathway for security and selective destruction that is needed.
