Detection device

The invention discloses a detection device which is used for quantitatively detecting the content of target substances in a sample. Target molecules in the sample can be quantitatively detected by comparing the signal intensity of a detection area with that of a reference area. The detection device is low in production cost, and detection results are accurate and reliable. 本发明公开了种检测装置，用于定量检测样本中的目标物质的含量。通过比较检测区信号强度和参比区信号强度可以对样本中的目标分子进行定量检测。该检测装置生产成本低，检测结果准确可靠。
