Plant extract mediated nanomaterials synthesis is one of the emanating fields of nanotechnology with voluminous applications in the physics, chemistry, biology, medicine, etc. Although different chemical techniques are on the brink of development, the rising concern for environmental contamination opens the path for biological synthesis as most of the chemical routes need toxic chemicals. The current piece of the study intended to synthesize silver nanoparticles by aqueous extract from the seed of the medicinal plant, Ocimum basilicum, under ambient conditions. A fixed ratio of plant extract to metal ion was prepared, and the color change was observed which proved the formation of nanoparticles. TEM analysis revealed silver nano-particles existed in a quasi-spherical shape with an average size of 11 nm in diameter. Moreover, the H2O2 sensing capacity of biologically synthesized AgNPs has also been studied
