Research description

Our group works on integrating biological models with electronic devices to generate systems that can be predictive of real biological systems, for drug discovery and therapeutics. We combine expertise in a wide range of disciplines including biochemistry, microbiology and cell biology on the bio side, to materials science, electronics and chemistry on the physical sciences and engineering side. We have two main activities, development of 3D organ on chip models of human tissues and organs and generation of native, complete membranes from human cells. In both cases we integrate with novel conducting polymer devices that can read out the biological function of the tissues and membranes and can thus be used to predict drug/therapeutic agent effect. We are currently working with the MRC Cancer Unit in Camridge to use our devices for impedance monitoring of tissue biopsies.
