摘要: Abstract Green synthesis of nanoparticles using seaweeds are fascinating high research attention nowadays and also gaining center in biomedical applications. In this work, we have synthesized biocompatible functionalized silver an aqueous extract seaweed Enteromorpha compressa as a reducing well stabilizing agent their efficient antimicrobial anticancer activity reported here. The UV–vis spectra AgNPs showed the characteristics SPR absorption band at 421 nm. chemical interaction crystalline nature were evaluated by FT-IR XRD studies. result shows typical Ag reflection peaks 38.1°, 44.2°, 64.4° 77.1° corresponding to (111), (200), (220) (311) Bragg’s planes. surface morphology composition samples observed HRTEM, EDS SAED pattern analyses. Spherical shaped nano structures size ranges between 4 24 nm with clear lattice fringes HRTEM image. This report reveals that mediated sustained delivery ions bacterial fungal been growth rate which was diffusion assay. favorable cytotoxicity against Ehlrich Ascites Carcinoma (EAC) cells IC 50 value recorded 95.35 μg mL −1 . study cost effective excellent biocompatibility thus could potentially be utilized pharmaceutical
