A ratiometric fluorescence sensor (c-CDs/Ru(bpy) 3 2+ ) based on the selective recognition of chitosan carbon dots (c-CDs) on ClO − and combine with Ru(bpy) 3 2+ was established for sensitive and visual monitoring of hypochlorite ion (ClO − ). Using this nanosensor, a highly sensitive assay of ClO −...
