Programmable Lab-on-a-chip Exploiting Magnetic MEMS for Medical Diagnostics and Biotechnology
The project will be supervised by Dr Ali Mohammadi in the Department of Electronics and Electrical Engineering, and Professor Simon Bending in the Department of Physics.
Miniaturisation of transducers in micro-electromechanical systems (MEMS) has greatly benefitted many modern technologies including smart phones, medical devices and implants, high sensitivity sensors etc. Magnetic microtransducers offer additional highly desirable features including operation in conducting media and conservation of field strength after scaling-down magnet size, which add significant functionality to their applications compared with other transduction mechanisms. Example applications include high throughput microfluidic chips, which drastically speed up single-cell array analysis for cancer diagnostic assays.
We have recently demonstrated proof-of-concept for a novel integrated and localised magnetic annealing process that offers a low-cost reprogramming technique for MEMS transducers. This innovative work exploits the temperature dependence of magnetic domains by combining electrothermal heating and magnetic annealing to selectively tune the anisotropy of individual magnetic elements on the same chip.
The proposed PhD project will build on this advance to deliver a magnetically programmable microfluidic prototype for lab-on-a-chip applications. The PhD student will have access to cutting edge laboratory equipment, microfabrication technologies and CAD tools available in the Centre for Advanced Sensor Technology (http://www.bath.ac.uk/elec-eng/research/cast/) in the Department of Electrical and Electronic Engineering and the David Bullett Nanofabrication Facility (http://www.bath.ac.uk/facilities/nanofab/) as well as external microfabrication foundries. The prospective student will travel to national and international conferences to communicate the research results within the Engineering and Physics communities and to end-users in Medical Science and Biotechnology.
Successful applicants will ideally have graduated (or be due to graduate) with an undergraduate Masters first class degree and/or MSc distinction (or overseas equivalent). Any English language requirements must be met at the deadline for applications.
