Amino-organoclays have been synthesized as organic-inorganic hybrid materials with a variety of centered metal cations such as Mg2+, Ca2+, Fe2+, Cu2+, Sn2+, Mn2+, Co2+, Al3+, Fe3+ etc. at sandwiched aminopropyl organo-functionalities, showing superior water-dispersibility via exfoliated dispersions of organoclay sheets by protonated amino groups in aqueous solution. Among those, we focused on synthesis of Cu-aminoclay to further investigate antibacterial activities, comparing with Cu salts. For the synthesis of Cu-aminoclay, we followed the method of the reported literatures. In order to evaluate the antibacterial activity of Cu-aminoclay, the inhibition growth assay of bacteria with Cu-aminoclay was confirmed by measuring absorbance at 620 nm, after mixing with suspensions with 2.5×10⁵colony forming units (CFU)/ml bacteria and Cu-aminoclay buffer solution. With micro-well plate and agar plate assays, the antibacterial activity of Gram positive species, Gram negative species, and fungal strains as well as antibiotic resistants (E. coli CCARM-12296, E. coli. CCARM-12386, S. aureus CCARM-3089, S. aureus CCARM- 3108) were examined.
