IMT Seminar: Microfluidics for Life Science in Two Parts - Dr David Inglis

Location: 

Hudson Beare - Classroom 8

Date: 

Friday, October 18, 2019 - 13:00 to 14:00

Abstract

In this talk, Dr Inglis will cover two recent areas of work: i) droplets for chemical signals transport, and ii) developments in deterministic lateral displacement.

i) The field of lab-on-a-chip is bringing many diagnostics to the patient, but this is not possible for all analyses. Sometimes, we will need to bring the sample to the machine. But transporting liquid samples even over millimetres causes signal dispersion that wipes out the temporal information content. Two phase flows using droplets can solve this problem. We have leveraged microfabrication and the water-oil Laplace pressure to create devices that can deliver and sample dynamic chemical signals.

ii) DLD is a method for particle separation that uses a periodic array of obstacles. The behaviour of particles can be modelled and studied using a unit cell with periodic boundary conditions. But when real-life devices are made we must design real boundaries that are not infinitely periodic. Here I will present a new approach to creating pseudo-periodic boundaries for DLD devices. The new boundaries have much better performance than anything previously described and should enable narrower, shorter, and higher throughput separation devices.

Bio

 

Dr Inglis received a Bachelor of Science in Engineering Physics from The University of Alberta in 2001 and a PhD in Electrical Engineering from Princeton University in 2007. He was an Australian Postdoctoral Fellow in the Physics Department of Macquarie University from 2008 to 2011. He is now a Senior Lecturer in the School of Engineering at Macquarie University in Sydney Australia.

Dr Inglis research interests lie in microfabrication for medicine and biology. He is well known for work on deterministic lateral displacement separations, and has published more than 40 research articles and patents that have been cited more than 2500 times. He is currently on Sabbatical at the Institute for Multiscale Thermo-fluids at the University of Edinburgh.
