摘要：

The present study reports the synthesis of silver (Ag) nanoparticles from silver precursor using plant biomaterials, Curcuma longa tuber powder and extract. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized silver particles. pH played a major role in size control of the particles. Silver nanoparticle synthesis was higher in tuber extract compared to powder, which was attributed to the large and easy availability of the reducing agents in the extract. Zeta potential studies showed that the surface charge of the formed nanoparticles was highly negative. The minimum bactericidal concentration (MBC) for Escherichia coli BL-21 strain was found to be 50 mg/L Immobilization of silver nanoparticles on cotton cloth using sterile water showed better bactericidal activity when compared to polyvinylidene fluoride (PVDF) immobilized cloth, but on consecutive washing the activity reduced drastically in sterile water immobilized cloth.
