Genetically engineered whole cells as biosensing systems in biosensors have been employed, in the past two decades, for the detection of a variety of analytes. In addition to being rapid, specific/selective, and sensitive, these whole-cell-based sensing systems provide information pertaining to the analyte bioavailability. This information is particularly important to study the effect of harmful/toxic...
Oxygen free radicals generation is a major cause of liver injury during reperfusion. Luminescence analysis has been recently proposed to measure free radical generation by isolated cells or organs, but it allows only global tissue luminescence. Using a special Saticon videocamera with image intensifier we aimed to visualize and localize oxygen free radical generation in isolated perfused livers exposed...
