Pyrene-porphyrin based ratiometric fluorescent sensor array for discrimination of glycosaminoglycans

Identification of Chinese baijiu from the same brand based on a graphene quantum dots fluorescence sensing array

“…Instrumental detection mainly includes headspace solid phase microextraction mass spectrometry, [15][16][17] liquid chromatography, 18,19 electronic nose analysis 20,21 and infrared spectroscopy. 22 The accuracy of the results is reliable. However, complex systems cannot be detected directly and extensive preprocessing is required.…”
