Fabrication of Conductive Nanoporous Membranes using Self-Assembling Block for Electrically Controlled Diffusive Flow

Ozalp E.I., Kim S., Sundar V., Zhu J.-G., Weldon J.A., Carnegie Mellon University, US

Nanoporous membranes have been recognized as promising candidates for drug delivery applications due to their small pore size and high surface-to-volume ratio1. The ultimate goal of smart drug delivery systems is to release a specific [...]

Combined effects of pump and capillary pressures for the filling of microchannel networks: the difficulty of synchronization

Berthier J., Diakite M.L., CEA-Leti (University Grenoble Alpes), FR

In this work, we first propose a model for the filling of a capillary tube driven by a pressure pump. It is shown that the filling time depends not only on the pump pressure but [...]

Plasmonic Nanocages as Photothermal Transducers for Laser Induced Heating and Bubble Generation

Karampelas I.H., Alali F., Furlani E.P., SUNY-Buffalo, US

A series of new computational models is introduced to demonstrate several photonic and thermo-fluidic details of the photothermal process associated with nanosecond-pulsed, laser-heated gold nanocages. Such models can be used to simulate energy conversion within [...]

Guidelines for choosing an appropriate turbulence model when simulating blood flows in cardiovascular devices

Simpson B.A.F., Tansley G.D., Griffith University, AU

A systematic and detailed comparative study of computational results with validating experimental data has helped define the turbulence models that are most appropriate for predicting the velocity fields and shear forces in blood flows. The [...]

An Integrated Biometric Platform for Evaluation of Targeted Drug Delivery

Liu Y., Thomas A., Uhl C., Wang S., He R., Lehigh University, US

In order to develop in vitro methods, which more closely resemble in vivo environments, a novel technology involving the use of microfluidic devices, which more closely mimic blood vessels has been developed. The technology has [...]

Low-cost spin-coatable, Transferable, and High-k Ion Gel Dielectric for Flexible Eletrowetting

Narasimhan V., Sanjairaj V., Park S.Y., National University of Singapore, SG

Electrowetting-on-dielectric (EWOD) is an emerging liquid-handling technology, enabling the wettability modulation of a liquid on a solid surface with an applied electric field. Recently, EWOD has been attractively used on flexible substrates to show potential [...]

Bottom-up Nanofabrication of Crystalline Structures of Magnetic Nanoparticles

Xue X., Furlani E.P., SUNY at Buffalo, US

A bottom-up approach to the nanofabrication of three-dimensional (3D) crystalline structures of magnetic core-shell nanoparticles is presented. The approach is based on self-assembly and involves the use of soft-magnetic template elements to guide the assembly [...]

Microfluidics for multiplexing of core needle biopsies

Mojica W.D., Oh K.W., Lee H., Xue X., Furlani E.P., University at Buffalo, US

Image guided biopsies for the procurement of diagnostic tissue has proven to be safe, cost effective and useful. However, the amount of tissue obtained is often diminutive and may be exhausted for conventional diagnostic purposes. [...]

On the dynamic contact angle in spontaneous capillary flow

Berthier J., Gosselin D., Delapierre G., CEA-LETI, FR

Capillary actuation of fluids is an interesting solution when the gravitational forces are small: this is the case in space , or in microfluidic systems where gravity is negligible. The onset of spontaneous capillary flow [...]
