Controlled release of ferulic acid from a hybrid hydrotalcite and its application as an antioxidant for human fibroblasts

Ferulic acid anions were intercalated in a Zn–Al layered double hydroxide. The materials generated by this process were characterised structurally and tested in two important applications: as in vitro drug delivery agents in a system that mimics biological conditions, for which a mathematical model describing the drug delivery profile was created, and as antioxidants for human fibroblasts.
