Silver
Spherical, 24 ± 8 nm Synthesized using P.
amarus
extract
Multidrug-resistant P.
aeruginosa
Excellent antibacterial
potential exhibited
Singh et al.
(2014)
Copper and zinc
oxide
Copper nanoparticle:
Spherical, 12–90 nm,
Zinc oxide
nanoparticle:
Aggregate form,
16–96 nm
Synthesized from
nonpathogenic E. faecalis
by extracellular enzymatic
method
Methicillin-resistant S.
aureus
20
Efficient antibacterial and
antibiofilm activity of both
nanoparticles
Ashajyothi
et al. (2016)
Silver
77.68 nm
Synthesized using F.
oxysporum,
strain 551
Methicillin-resistant S. aureus
strains N315, 101, and 107,
carbapenemase- producing E.
coli
(E. coli
KPC 131 and
133), carbapenem-resistant A.
baumannii
Growth of drug-resistant and
multidrug-resistant strains
inhibited
Scandorieiro
et al. (2016)
In combination with oregano
essential oil, bio-silver
nanoparticles showed much
lower minimum inhibitory
concentration values compared
to individual treatment
Combination treatment caused
a faster reduction in colonyforming units per milliliter
than individual treatments
Zinc oxide
Spherical, 22.5 nm
Synthesized using leaf
extract of Aristolochia
indica
Multidrug-resistant P.
aeruginosa, A. baumannii, E.
coli, and
methicillin-resistant
S. aureus
Strong bactericidal properties Steffy et al.
(2017)
Both strains significantly
inhibited
