Hardware |
As the joint of biological and non-biological research, this device aims to detect the fluorescent intensity of GFP and calculate the concentration of the chemicals (Cr (VI), beta-lactam, and tetracycline, respectively) detected based on it. We can then assess the quality of the sample detected. |
The mechanism of this device is simple (figure). The exciting light coming from blue LED through 490nm narrowband filter, which only allow 490nm light to pass through. The filtered light then penetrates our test chip. If GFP exists on our test chip, it would transform the frequency of the excitation light into about 520nm, which is the only frequency of light that can pass through the 517nm narrowband filter. Then our sensor will be able to detect the intensity of the light and calculate the content of GFP, indicating the composition of the tested sample with our mathematical model. The characteristic of our device is that it is really CHEAP. Although it costs less than 300RMB in total and can easily cooperate with our biological products. |
