Impedance interrogated affinity biosensors for medical applications: novel targets and mechanistic studies
P.A. Millner, R.L. Caygill, D.J.R. Conroy and M.A. Shahidan, University of Leeds, UK
To date, most biosensors for medical applications have focused either on small metabolites such as glucose, or on protein markers of disease (cancer, heart attack and others) or other conditions such as pregnancy. However, rapid measurement of other classes of analyte would clearly be useful for diagnosis and prognosis during treatment. These include ions, carbohydrates and microorganisms such as viruses and bacteria. We discuss the approaches taken to producing reagentless biosensors to these three types of analyte that are amenable ...
