•Simple, effective and eco-friendly method.•The silver nanocomposites were crystalline nature and shows good stability.•Functionalized Ag nanocomposites exhibit enhanced biological activity.
The aim of the study is to investigate the antibacterial properties and characterization of β-cyclodextrin (β-CD) stabilized silver – chitosan nanocomposite (Ag-Cts NCs). An effective and eco-friendly technique for the synthesis of Ag-Cts NCs in the presence of a strong stabilizing agent β-CD is described. The well formed nanocomposites were characterized by the Ultraviolet Visible spectroscopy (UV–Vis), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Photoluminescence spectroscopy (PL), Scanning electron microscope (SEM/EDS), Atomic force microscope (AFM), High resolution transmission electron microscope (HR-TEM) and Zeta potential measurement (ZP). The results confirmed that the poly dispersed Ag-Cts NCs are less than 15 nm in size with spherical shape and show good stability. The antibacterial activity was also investigated and β-CD coated Ag-Cts NCs showed a promising bacterial activity against gram negative Escherichia coli (E. coli) and gram positive Staphylococcus aureus (S. aureus) micro-organism.
