A ratiometric fluorescent probe combined with smartphone technology based on cellulose for the detection of hypochlorous acid.

Hypochloric acid (HClO) is a reactive oxygen species (ROS). ROS is an important component that has antibacterial effects on the biological immune defense system. Therefore, the detection of HClO has become an unavoidable issue.

Extraction Optimization and Effects of Extraction Methods on the Chemical Structures and Antioxidant Activities of Polysaccharides from Snow Chrysanthemum ().

In order to explore snow chrysanthemum polysaccharides (SCPs) as functional food ingredients and natural antioxidants for industrial applications, both microwave-assisted extraction (MAE) and ultrasonic-assisted extraction (UAE) were firstly optimized for the extraction of SCPs. Furthermore, the effects of conventional hot water extraction, UAE, and MAE on the chemical structures and antioxidant activities of SCPs were investigated. The maximum extraction yields of SCPs extracted by UAE (4.
