Natural Biopolymer-Based Injectable, Self-Healing Hydrogel via Self-Assembly of Pectin and Quaternized Guar Gum for Targeted Treatment of Colon Cancer.
A biocompatible, injectable, and self-healing hydrogel was constructed via electrostatic self-assembly of anionic pectin (PEC) and cationic quaternized guar gum (QGG). The optimized PEC/QGG hydrogel (QPE5, 1:3.5 ratio) exhibited rapid gelation (1.5 min), high yield (95.7%), shear-thinning behavior (viscosity decrease f...
