Quercetin Enhanced Cellulose Nanocrystals for the Removal of Harmful Algae Phaeocystis Globosa

The Phaeocystis globosa widely exists in the seawater, which becomes a great threat for the health of humans and animals in the ecological ecosystem. In this work, we reported a promising control strategy with quercetin(QT) enhanced cellulose nanocrystals (CNC). The quercetin enhanced cellulose nano...
