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

Multivalent drug delivery carrier for the targeted delivery of platinum anticancer agents to hepatocytes. Hepatocellular carcinoma (HCC) is often treated with chemotherapy using cytotoxic drugs. This systemic treatment results in the distribution of the drug throughout the body.

Hepatocellular carcinoma (HCC) is often treated with chemotherapy using cytotoxic drugs. This systemic treatment results in the distribution of the drug throughout the body. Employing a polymer particle as a drug carrier for these drugs ensures a temporal control of the release and therefore supply of the drug within the body. By attaching carbohydrate moieties onto the surface of the polymer particle the drug carrier can specifically be recognized by cell receptors, thus allowing a targeted delivery of the drug to the desired area in the body. A range of carbohydrate-based drug carriers will be synthesized and tested towards their interaction with hepatocytes to allow optimisation of this drug carrier system.
