Abstract

276-281<span style="font-size:11.0pt;mso-bidi-font-size: 10.0pt;font-family:" times="" new="" roman","serif";mso-fareast-font-family:"times="" roman";="" mso-ansi-language:en-gb;mso-fareast-language:en-us;mso-bidi-language:ar-sa"="" lang="EN-GB">The present study reports the synthesis of silver nanoparticles (AgNPs) using aqueous extract of a seaweed, Gracilaria corticata. Extremely stable AgNPs were characterized by UV-Vis spectrophotometer, FTIR, XRD, TEM and EDS analyses. The nanoparticles exhibited maximum absorbance at 424 nm in the UV spectrum. The presence of proteins was identified by FTIR. TEM micrograph revealed the formation of polydispersed and spherical shaped nanoparticles with the size range of 10-50 nm and the presence of elemental silver were confirmed by EDS analysis. These nanoparticles showed cytotoxic activity against MCF7 cells.</span
