Photocatalytic and antibacterial activity of bismuth and copper co-doped cobalt ferrite nanoparticles

Green synthesis, characterization, and biological activities of saffron leaf extract‐mediated zinc oxide nanoparticles: A sustainable approach to reuse an agricultural waste

“…Further, metallic ions such as Zn 2+ are mutually attracted to membrane cell wall that will damage the bacterial genome, eventually causing the death of bacteria by breaking its cell surface. [ 37,38 ] The antibacterial activity also depends on the production of reactive oxygen species including superoxide, hydrogen peroxides, and hydroxyl radicals. [ 29 ] The antibacterial efficacy of antimicrobial compounds is related to the inhibition zone; in other words, if the diameter of inhibition zone is larger, then bacterial strains are more sensitive to that compound.…”

Progress, Challenges and Opportunities in Divalent Transition Metal-Doped Cobalt Ferrites Nanoparticles Applications

“…The particle size, morphology, surface area, increase in oxygen vacancies, chemical molecule diffusion ability and discharge of metal ions also play important roles in the bactericidal activity [38]. Good antibacterial activity against E. coli and grampositive S. aureus of Cu 0.5 Co 0.5 Fe 1.9 Bi 0.1 O 4 NPs synthetized by combustion technique was obtained, due to the co-doping of Cu and Bi in Co ferrite [39].…”

Co0 superparamagnetic nanoparticles stabilized by an organic layer coating with antimicrobial activity

“…Nanoparticles are being used with this purpose. 35,36 The Co based nanoparticles has been studies against Staphylococcus aureus, these include cobalt ferrite nanoparticles [37][38][39][40] and cobalt oxide nanoparticles, 41,42 but there are a few investigation that used only metallic cobalt nanoparticles without conjugated at other nanoparticles or nanomaterials. For this reason, in this study, we evaluated the antimicrobial properties of Co 0 @C-NPs synthesized by a solvothermal technique against Gram-positive bacteria (S. aureus) ( Fig.…”
