Abstract

Silvernanoparticlesweresynthesizedusingthefruitextractsof Momordica charantia (Mc-AgNPs). The
structural characterizationof Mc-AgNPs wasperformedbyUV–vis spectroscopy,X-raydiffraction(XRD),
Fourier transforminfraredspectroscopy(FTIR)andTransmissionelectronmicroscopy(TEM).UV–vis
recordedtheabsorbancespectraat460nm.XRDshowsthecrystallinenatureofsilvernanoparticleswith
variousBragg'sreflection peaksat111,200,220and311.FTIRspectraofthesynthesized Mc-AgNPs
showedstrongbandsat1382,1203,1151,1102,1013and654cm�1 which correspondstoO–H, C–H, C–C,
C–OH andC–N groups.TEMshowedthesphericalshapeof Mc-AgNPs withparticlesizebetween16nm.
The antibacterialactivityof Mc-AgNPs wastestedagainstGram-positiveandGram-negativebacteria. Mc-
AgNPs showedgreaterinhibitionof Enterococcusfaecalis at 100 mg ml�1 compared to Aeromonashy-
drophila. Thebiofilm inhibitionof Mc-AgNPs wasalsohigheragainst E. faecalis comparedto A.hydrophila.
