We developed a green, inexpensive and simple method for the synthesis of silver nanoparticles from the Opuntia Ficus (OF) 2+ Indica fruit juice. The synthesized AgNPs were used as sensor for the detection of toxic metal (Hg ) using colorimetric technique as well as to investigate the antimicrobial activities against number of clinical isolates of human microbes. The synthesized AgNPs nanoparticles were characterized using UV–Vis spectroscopy, FTIR spectroscopy, scanning electron microscopy and EDX methods. The green synthesized AgNPs showed surface plasmon resonance absorption band at 441 nm, which conﬁrm the formation of AgNPs that were also established by FTIR and EDX analyses. The colour of AgNPs changes 2+ from blood red to white in the presence of Hg only, which can be differentiated and detected by the naked eye within few seconds without the prerequisite of surface amendment from other metals (Co, Ni, Fe, Mn, Pb, Zn, Cr). A good linear response 2 2+ −3 −8 (R = 0.97) was obtained towards Hg ions in the concentration range of 10 to 10 M. In addition, all growth of the tested microbial stains ceased in varied range. OFAg-2 had the highest inhibition effect followed by OFAg-1, while OF did not
