Identification and Content Detection of Citrus Juice Based on Nanoparticle-DNA Technology

This experiment detected the luminescence intensity of the Nanoparticles of citrus juice and calculated its DNA concentration using the Nanoparticles-DNA technology, which can be used to determine the authenticity of citrus juice and the test of DNA concentration. The results showed that the linear equation between the concentration of DNA and the intensity of the luminescence was y = -0.0003x + 2.1454, which presented a good linear relation (R2 = 0.999) in the range of 5.0 ~ 780 ug/mL.
