The prepared ternary systems (Ch/Q- and Ch/CA-Ag NPs) are expected to have better cytotoxic properties than binary systems (chitosan–silver and quercetin–silver), which showed moderate cytotoxicity in vitro at higher doses against different cancer

Unlike other metal oxide binary systems where TiO2 is coated with SiO2 [68][69], in this study, the mSiO2@NiPS core–shell structure was coated with TiO2 nanoparticles, which readily absorb in the UV region. This suggests that the presence of TiO2 on the
