  • Tooth Enamel - an overview | ScienceDirect Topics

    Yeom et al. (2017), inspired by the enamel structure, made ex vivo replicate columnar nanocomposites by sequential growth of zinc oxide (ZnO) nanowire carpets followed by layer-by-layer (LBL) deposition of a polymeric matrix around the carpets. The LBL matrix was made of polyallylamine (PAAm) and polyacrylic acid (PAA).
