%X A procedure for the green synthesis of silver nanoparticles (AgNPs) using<span style=\"font-family:;\" \"=\"\"> </span><i><span style=\"font-family:Verdana;\">Cannabis sativa</span></i><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:Verdana;\">(hemp plant) as a stabilizing
media was developed and antibacterial activity was tested. Within 30 minutes of
heating</span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">the mixture
of silver nitrate and hemp extract, the formation of silver nanoparticles took place
under the complete absence of a chemical reducing or an additional stabilizing agent.
The so-formed AgNPs were characterized using different optical spectroscopy and
electron microscopy techniques. The initial formation of AgNPs was established from
UV-Vis data based on </span><span style=\"font-family:Verdana;\">surface plasmon resonance (</span><span style=\"font-family:Verdana;\">SPR) of AgNPs at ~417 nm. The exact size, shape,</span></span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:Verdana;\">and elemental composition of
AgNPs </span><span style=\"font-family:Verdana;\">were</span><span style=\"font-family:Verdana;\"> established from ESEM images and EDS data.</span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">The antibacterial activity of these nanoparticles was
studied on Gram-positive </span><i><span style=\"font-family:Verdana;\">Staphylococcus aureus</span></i><span style=\"font-family:Verdana;\">,
and Gram-negative</span><i><span style=\"font-family:Verdana;\"> Escherichia coli</span></i></span><i><span style=\"font-family:;\" \"=\"\"> </span></i><span style=\"font-family:Verdana;\">following Disk diffusion and Minimum Inhibitory Concentration (MIC) tests.
Results showed that the biosynthesis of silver nanoparticles using hemp extract </span><span style=\"font-family:Verdana;\">could be</span><span style=\"font-family:Verdana;\"> a simple,</span><span>inexpensive,
and biocompatible method.</span>
