Cataluminescence strategy for rapid identification of sunscreen cosmetics based on its characteristic composition served as catalyst

In this work, a novel cataluminescence(CTL) strategy was developed for fast differentiation of sunscreen cosmetics. The CTL reactions occurring on the surface of sunscreen cosmetics whose characteristic composition served as catalyst. Normalization methodology was utilized to process sensor array signals, we developed a dimensionless quantity called “relative signal (Skr)” to characterize the sensor response. Firstly, aldehydes are eligible for...
