A nano-electronic detection system which is based on the principle that the vibration frequency of piezoelectric quartz crystal is sensitive to the load of its electrodes surface

also combined with the control ability of FPGA

single-chip and that nano-magnetic beads have the ability of improving the load response and biochemical reactions is designed

the system hopefully will be used for the detection of early lung cancer.According to the system testing result of distilled water and lung cancer cell CPA—Y2

which show that the system has a good linearity and can accurately reflect the quality or content of biological material.This system has important value of reference for early diagnosis of lung cancer.
