Synthesis of CdTe QDs/single-walled aluminosilicate nanotubes hybrid compound and their antimicrobial activity on bacteria

摘要: The use of molecular conjugates quantum dots (nanocrystalline fluorophores) for biological purposes have received much attention due to their improved activity. However, relatively, little is known about the synthesis and application aluminosilicate nanotubes decorated with (QDs) imaging treatment pathogenic bacteria. This paper describes a first time, single-walled (SWNT) (imogolite) as one-dimensional template in situ growth mercaptopropionic acid-capped CdTe QDs. new nanohybrid hydrogel was synthesized by simple reaction pathway enhanced optical properties were monitored fluorescence UV–Vis spectroscopy, confirming that these favors confinement effects net In addition, studies FT-IR spectroscopy transmission electron microscopy confirmed non-covalent functionalization SWNT. Finally, antimicrobial activity SWNT coated QDs toward three opportunistic multi-resistant pathogens such Salmonella typhimurium, Acinetobacter baumannii, Pseudomonas aeruginosa tested. Growth inhibition tests conducted exposing growing bacteria QDs/SWNT hybrid compound showing nano-structured composite potential agent heavy metal-resistant
