The study aimed to synthesize copper
nanoparticles (CuNPs) using Brassica oleracea var.
gemmifera extract (BOE) and investigate their
antioxidant and antibacterial properties. The BOE-
mediated CuNPs (BOE-CuNPs) were successfully
synthesized utilizing reducing and stabilizing properties
of B. oleracea var. gemmifera extract. The
nanotechnology features showed that BOE-CuNPs were
nano in size (106.59 ± 4.77 nm), slightly agglomerated,
stable (-12.41 ± 1.88 mV), and made up of mainly copper.
The green synthesized BOE-CuNPs have potential
antioxidant features and have EC50 values (concentration
essential to inhibit 50% of free radicals) of 334.09 ± 17.70
μg/mL and 361.43 ± 12.91 μg/mL in DPPH and ABTS
free radical scavenging activity, correspondingly, and
could be useful in treating oxidative-stress-mediated
conditions. Also, as-synthesized BOE-CuNPs have
potential antibacterial activity and showed the highest
antibacterial activity against Escherichia coli – MTCC
41 and Listeria monocytogenes – MTCC 657, and could
be useful as an antibacterial representative in the
biomedical field. However, to utilize BOE-CuNPs, an in-
detailed functional and toxicological profile of BOE-
CuNPs needs to be performed.
