Detection of biological reactions by AlGaN/GaN biosensor

We have investigated application of AlGaN/GaN cell-based biosensors for detection of biological reactions in response to the drug ionomycin. The device sensitivity was dependent on environmental factors such as temperature and atmospheric composition. A significant improvement in signal amplitude was obtained through stabilisation of measurement conditions. These results are an important step in development and optimisation of reliable AlGaN/GaN cell-based biosensors.
