We have designed a facile biological way for rapid synthesis and immobilization of gold and silver nanoparticles on alginate films using leaf extract of Cassia auriculata. The prepared gold bio-nanocomposite (Au-BNC) and silver bio-nanocomposite (Ag-BNC) were characterized by UV-vis spectroscopy, Fourier transform infrared spectroscopy, Transmission electron microscopy and Thermal analysis. The bio-nanocomposites exhibited good antibacterial activity against both gram positive (Bacillus subtilis) and gram negative (Escherichia coli) bacteria. The metal nanoparticle embedded films have number of applications in catalysis, optical biosensors, electronic, biomedical devices and environmental remediation. (C) 2015 Elsevier B.V.
