    Evaluation of Justicia adhatoda Linn. extract-loaded layered double hydroxide nanohybrid for sunscreen applications
    (Institute of Chemistry Ceylon, 2025-05) Gunaratne,W. A. S. B; Silva,H. I. C. De
    Safety concerns regarding synthetic sunscreens have increased the demand for botanical alternatives rich in phytochemicals with natural photo-protectant properties. Layered double hydroxides (LDHs) offer biocompatibility, tunable composition, high anion- exchange capacity, and controlled release. This study focused on developing a plant extract-incorporated LDH nanohybrid and evaluating its photostability and antioxidant activity. Based on the UV blocking ability at UVA and UVB regions, J. adhatoda was selected.
