(A) DSC curves of triclosan (TCS), methacrylated glycol chitosan (MGC), and MGC-g-CD-ic-TCS monitored from 50 °C to 150 °C, (B) storage/loss moduli of MGC-g-CD-ic-TCS hydrogel precursor solution measured from 0 Hz to 10 Hz before and after visible light irradiation for 200 s, (C) swelling ratio of MGC-g-CD-ic-TCS measured at determined time intervals (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 h), (D) Cumulative TCS release percentage calculated at determined time intervals (0.5, 1, 2, 3, 4, 7, 12, 15, 20, 25, 33, and 48 h). Swelling ratio and release behavior tests were performed in triplicate (n = 3).
