Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites.

Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately microelectronic engineering methods will be used. This will give control over the attachment process with potential benefits of orienting attaching molecules, minimising non-specific attachment and enriching diagnostics by enabling interrogation of the force of attachment.Read moreRead less

This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzymatic reactions through which the analyte will convert to much simpler, reactive and hence measurable molecules. This project will enable to design miniaturised sensors for point-of-care detection of biomolecules that cannot be yet evaluated by the end users.Read moreRead less
Biomolecular activity modulated by interaction with nanostructures. Nanotechnological methods are able to reliably fabricate artificial nanostructures with dimensions similar to those of large biomolecules (a few to tens of nanometers). This study focuses on the interaction of artificial nanostructures with biomolecules such as proteins and DNA, and will enable scientists to better understand biomolecular recognition and binding events, which are central to all biological processes.

This project aims to investigate molecular mechanisms involved in the formation of undesired biological deposits on synthetic materials and thereby help establish the scientific basis for the rational design of materials with improved compatibility with biological fluids and the engineering of a new generation of biomedical implant devices and bio-diagnostic devices. It is well known that proteins accumulate on synthetic solid surfaces. This project proposes to investigate whether lipids and lipoproteins also play key roles in the initiation of biological adsorption processes. Combined with the study of the interfacial forces responsible, this information will guide the design of preventative strategies.Read moreRead less
