Discriminatory antibacterial effects of calix[n]arene capped silver nanoparticles with regard to gram positive and gram negative bacteria.
نویسندگان
چکیده
Silver nanoparticles capped with nine different sulphonated calix[n]arenes were tested for their anti-bacterial effects against B. subtilis and E. coli at an apparent concentration of 100 nM in calix[n]arene. The results show the para-sulphonato-calix[n]arenes are active against Gram positive bacteria and the derivatives having sulphonate groups at both para and alkyl terminal positions are active against Gram negative bacteria. The calix[6]arene derivative with only O-alkyl sulphonate groups shows bactericidal activity.

A novel azo-Schiff base ligand (L) was prepared by reacting 2-hydroxy-5-(pyridine-4-yldiazenyl) benzaldehyde with 1,2-phenylenediamine. Moreover, Silver nanoparticles (Ag-NPs) and Cadmium sulfide nanoparticles (CdS-NPs) were prepared by employing azo-Schiff base ligand (L) as capping and reducing agent. The solid-state fluorescence spectroscopy was used to investigate the interaction between L ...
