Pioneers of Miniaturisation Prize
Micro- and nanoscale porous media analogs (PMA) have been fabricated into Congratulations to Ali Khademhosseini a variety of materials including elastomers, thermosets, silicon and glass. We use PMA to study fluid and solute transport in networks the mimic the geometric and environmental conditions of real reservoirs. We are currently focused on measuring solute transport between microscale and nanoscale pores using tracer transit time measurements and macrotransport theory.
Lab on a Chip and Corning Inc are pleased to announce the 2011 recipient of the Pioneers of Miniaturisation Prize, Ali Khademhosseini. The Prize recognises outstanding achievements and significant contributions to the understanding and advancement of micro- and nano-scale science. Among his many achievements and awards Ali has also: Developed unique approaches of interfacing cells within microfluidic channels; including patterning of surfaces/immobilisation of cells in microstructures/developed microfluidic microvasculature systems for early diagnosis of drug efficacy in vitro prior to costly animal studies/engineered nanoparticle surfaces to control their interaction with the surrounding tissue for drug targeting.

PAPER Neeves et al. Single- and two-phase flow in microfluidic porous media analogs based on Voronoi tessellation
Our work on two-phase flow in porous media analogs was featured on the cover of Lab on a Chip, Vol 12, January 2012. 1473-0197(2012)12:2;1-7
1 mm Displacement of oil (clear fluid) by brine (dark fluid) in a pore scale network typical of carbonate formations. Channels have a 10 um x 10 um cross-section. The effect of hydrophilic (left) and hydrophobic (right) walls is shown.
50 um Gas (light fluid) displacement of brine (dark fluid) in 100 nm X 5 um channels.
