US scientists have developed a sensor system for profiling the protein content of human blood serum without needing individual receptors for each separate protein. The technique could be used to provide cheap preliminary disease diagnosis information, saving time and money by reducing unnecessary testing.There is a direct link between levels of protein in human serum and disease, making protein levels an attractive target for sensors and diagnostics. However, with over 20,000 proteins present in human serum at a range of different concentrations, developing an effective sensor has been a challenging task.Pattern recognition sensing uses detector systems that interact with many...
