WebFeb 1, 2024 · The pH-sensitive color indicator was prepared by adsorbing shikonin to an ash-free paper. • The shikonin solution showed distinctive color changes in a wide range of pH 2–12. • The indicator exhibited high antioxidant activity. • The indicator was stable, and sensitively responded to the pH changes. • WebWe also found that the swelling degree of the hydrogel with increased STPP content was more pH sensitive when the SCTs were moved from the pH 1.2 to pH 7.4 medium. The swelling ratio was in the range of 919.7–2113.3% and 954.7–1959%, respectively, when the STPP concentration was 1 wt% and 0.75 wt%.
