Photodynamic therapy (PDT) eradicates tumor cells by the light-stimulated reactive oxygen species, which also induces lipid peroxidation (LPO) and subsequently ferroptosis, an iron-depended cell death. Ferroptosis has a tremendous therapeutic potential in cancer treatment, however, the ferroptosis efficiency is largely limited by the available iron in cells. Through hijacking the CD44-mediated iron endocytosis of hyaluronan (HA), here PDT with enhanced ferroptosis was realized by a HA@Ce6 nanogel self-assembled from HA, a photosensitizer Chlorin e6 (Ce6) and Fe as cross-linkers.

Hyaluronic acid (HA), a vital polysaccharide naturally present in human tissues, is widely utilized in the food, pharmaceutical and cosmetic industries due to its diverse functionalities and bioactivity. Rapid and accurate quantification of HA is essential for the quality control of its products. Enzymatic quantification methods, known for their simplicity and high specificity, were employed for polysaccharide measurement.

Camptothecin (CPT) exhibits potent anticancer activity, but its clinical application is limited by poor solubility and severe side effects. Hyaluronic acid (HA) is gaining attention in drug delivery systems due to its excellent biocompatibility and tumor-targeting properties. In this study, we conjugated CPT to the reducing end of ultra-low molecular weight HA to create a series of HA-decorated CPT conjugates.

Fucosylated chondroitin sulfate (FCS) from Holothuria mexicana (FCS) was selected for investigation because of its intriguing branch features. Selective β-eliminative depolymerization and the bottom-up assembly were performed to unravel that FCS consisted of a {D-GlcA-β1,3-D-GalNAc} backbone and branches of alternating Fuc (55 %) and D-GalNAc-α1,2-L-Fuc (45 %), the highest proportion of disaccharide branch reported to date. In branches, sulfation could occur at every free -OH site except O-3 of GalNAc, being the most complex and various structure features of natural FCS.
