FT-NIR spectroscopy is a useful tool to identify textile samples, with distinct spectral features observed at wavelengths >1350 nm. This approach can be applied to authentication of natural and synthetic consumer textile products.

The flavonoids that dominate the fluorescence spectra for honey shown in Figure 1 are polyphenols. These plant metabolites determine the color, aroma, and flavor of the honey, and provide antioxidant and other health benefits. The fluorescence spectrum for each honey sample illustrates the sensitivity of fluorescence spectroscopy for characterizing honey.

Although most often associated with Christmas, multicolored holiday lights are used year-round as an appealing decorative accent.
