At present there is a need for fast and detailed chemical analysis of complex samples, such as those important to biomedical diagnostics and forensic science. Innovative technology will be developed here in order to reduce analysis time whilst maintaining the integrity of the chemical information contained within the sample. This step change in separation science will directly aid biomedical diagnostics, forensic sample determination and industrial process monitoring through decreased analysis time with an increase in the chemical information gained. By performing chemical separations on a microfluidic scale a reduction in both the cost of analysis and impact of solvent waste on the environment will be achieved.Read moreRead less
A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood.

Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of interest to capture the miRNA. Application of a magnetic field allows the levels of miRNA to be detected electrochemically. The expected outcome is a commercialisable biosensor for miRNA both as a diagnostic early detection device and a prognostic device for a range of miRNA biomarkers.Read moreRead less

The first generation of single entity measurement tools for analysis: This fellowship project aims to develop a new type of diagnostic device that measures single molecules or single cells. Such measurements seek to revolutionise analysis by allowing heterogeneity and rare events in samples to be identified, rather than the average information provided by existing tools. With single molecule devices, the heterogeneity in response enables the development of multiplexed, calibration free sensors. The outcomes of the project are hoped to be completely new thinking on performing measurements, new knowledge regarding heterogeneity in biology and the potential for novel commercialised sensors. It is expected that this will be important not only in biological discovery, but also in providing far more robust sensors for applications such as environmental monitoring, disease prediction, personalised medicine or drug discovery.Read moreRead less
