About the Project

Biomedical sensing is an area of wide-ranging importance with significant fundamental and applied research that continues to push the limits, in terms of analytical targets, sensitivity, robustness and versatility. Resistive-pulse sensors, such as solid-state nanopores and nanopipettes, are particularly interesting here, because they are a class of single-molecule sensors with unique capabilities and they can be augmented using engineered and functional DNA nanostructures ("carrier-enhanced" resistive-pulse sensing).

In this project, we will expand this concept, using DNA nanotechnology and self-assembly, to create novel "mesocopic" devices, where sensor readout is performed multiple, potentially thousands of times, to achieve unprecedented levels of accuracy and reproducibility.

This is a highly interdisciplinary project, involving nanofabrication, DNA self-assembly, electronics, automation and advanced data analysis. The ideal candidate would therefore have a background in chemistry or physics, or in a related area, be collaborative and importantly should have willingness and enthusiasm to be challenged and learn new things. Previous coding experience in Matlab or Python is advantageous, but not a must.
