“…(Ravikumar et al 2011;Taylor and Webster 2009;Tran et al 2010). One study has reported antibacterial activity of Fe 2 O 3 nanoparticles on a number of bacteria in their planktonic forms (Gokulakrishnan et al 2012). Another study by He et al, found no inhibitory effect of Fe 2 O 3 nanoparticles on the growth of E. coli.…”

“…(Ravikumar et al 2011). A recent study by Gokulakrishnan et al investigated the antibacterial activity of Fe 2 O 3 nanoparticles on a number of bacteria in their planktonic forms (Gokulakrishnan et al 2012). In the present study, antibacterial activity of CeO 2 and Fe 2 O 3 nanoparticles on a larger panel of gram-positive and gram-negative bacteria in both the planktonic and biofilm cultures were evaluated.…”

Metal oxide nanoparticles have been suggested as good candidates for the development of antibacterial agents. Cerium oxide (CeO 2 ) and iron oxide (Fe 2 O 3 ) nanoparticles have been utilized in a number of biomedical applications. Here, the antibacterial activity of CeO 2 and Fe 2 O 3 nanoparticles were evaluated on a panel of gram positive and gram negative bacteria in both the planktonic and biofilm cultures. Additionally, the effect of combining CeO 2 and Fe 2 O 3 nanoparticles with the broad spectrum antibiotic ciprofloxacin on tested bacteria was investigated. Thus, minimum inhibitory concentrations (MICs) of CeO 2 and Fe 2 O 3 nanoparticles that are required to inhibit bacterial planktonic growth and bacterial biofilm, were evaluated, and were compared to the MICs of the broad spectrum antibiotic ciprofloxacin alone or in the presence of CeO 2 and Fe 2 O 3 nanoparticles. Results of this study show that both CeO 2 and Fe 2 O 3 nanoparticles fail to inhibit bacterial growth and biofilm biomass for all the bacterial strains tested. Moreover, adding CeO 2 or Fe 2 O 3 nanoparticles to the broad spectrum antibiotic ciprofloxacin almost abolished its antibacterial activity. Results of this study suggest that CeO 2 and Fe 2 O 3 nanoparticles are not good candidates as antibacterial agents, and they could interfere with the activity of important antibiotics.

“…These findings do not correlate with the observations of previous screenings of medicinal plants for antimicrobial activity, where most of the active plant extracts showed activity against Gram-positive strains only [56][57][58][59] . Because Gram-negative organisms were reported to be less susceptible to the action of antibacterials, since they possess an outer membrane surrounding the cell wall, which restricts diffusion of hydrophobic compounds through its lipopolysaccharide covering [60][61][62][63][64][65][66][67] . Besides the difference in sensitivity might be ascribed to the difference in morphological constitutions between Gram-positive and Gram-negative organisms.…”

“…There are many sources of NP synthesis, but the green approaches are gaining popularity. Plant parts such as, the leaf, the bark, the flower, the peel, and the seed and microorganisms such as fungi, bacteria, algae, yeast, actinomycetes, and enzymes offer clean, eco-friendly, non-toxic machinery for their synthesis, which is compatible with pharmaceutical and cosmeceutical applications [9][10][11] . These NMs have long been documented to exhibit microbiocidal, microbiostatic actions and serve as potential antibacterial agents in medical and industrial applications [12] .…”

Qidwai, et al.: Biogenic Advances in NanoparticlesInnovations in the nanotechnological arena have paved a path leading to nano-revolution, which has most recently unfurled the role of plants in the biogenic synthesis of nanoparticles. Though synthesis of nanoparticles can be accomplished through physical and chemical techniques, biological course of synthesis has proficiently proved competent over other techniques. The problem of evolving multidrug resistant bacteria, due to irrational use of antibiotics, makes the biogenically synthesized nanoparticles attractive, due to their promising efficacy with negligible side effects. Consequently, the nanoparticles becoming better substitutes for conventional treatment besides overcoming all the limitations. Nanoparticles have great stability and potent antibacterial activity. The uniqueness lies in their size (10 and 500 nm) and dimension offers these particles to dynamically communicate with biomolecules on the cell surfaces and within the cells, so proficiently to decode and designate various biochemical and physiochemical properties of the cells. The present review aims to recapitulate various emerging efforts in the biogenic synthesis of nanoparticles, most significantly their unique mechanisms of action with different approaches as well as the factors that may add up to their antimicrobial activity.
