Russian scientists from the Institute of Chemical Biology and Fundamental Medicine developed a molecular biosensor for detecting cancer on its early stages, as well as genetic anomalies of fetus during pregnancy.
      
      The sensor is silicon “sieve”, which micro-channels have predetermined shapes and are arranged in a certain order. Such “sieve” allows sorting out cancer cells, because they are larger than ordinary ones. If human blood stream contains such cells, the sensor can catch them and forward to further analysis.
      
      The innovation is extremely important for early diagnostics of cancer, since it shows rare cell events, taking place at very early stages of cancer development, or when metastasis begins.
