Current Projects


Cells on chips How do cells respond in the first few minutes after stimulation with a growth factor, drug or antigen? Are there characteristic signalling and metabolic responses? We have developed biocompatible arrays of microelectrode sensors to examine the effects of angiogenin and VEG-F on aortic endothelial cells and used similar approaches to look at bacterial antigens and macrophages











Microfabrication and microfluidics Sometimes it is advantageous to do bioanalysis off-line on a sample either from cells or living tissues. Such samples are typically tiny and new approaches to analytical methods are required. We've developed chromatographic techniques on a chip and combines this with droplet flow microfluidics to act as a tiny fraction collector.
