“…The band at 1653 cm -1 present in the spectrum of the as-prepared sample is assigned to bending vibrations of water molecules [45]. In the spectrum of the as-prepared sample the band at 1322 cm -1 is attributed to the symmetric C=O bond vibrations [44].The band at about 833 cm -1 in the asprepared sample is due to Fe-OH bond vibrations [33]. The peak appearing in the region of 669 cm -1 is due to the presence of hydroxyl group in the as-prepared sample [46].…”

“…3. The broad band observed in the region 3363 cm −1 corresponds to O-H stretching vibrations arising from the moisture present in KBr which is used for making pellets in an open air [44]. The band at 1653 cm -1 present in the spectrum of the as-prepared sample is assigned to bending vibrations of water molecules [45].…”

“…Figure 1 shows that particles were <100 nm with uneven size and shape (circular, oval, stretched or even irregular shape). This may be the result of the synthesis protocol used to manufacture these nanoparticles since morphological uniformity of nZnO may be obtained by optimising the calcination temperature45 or by adjusting the concentration of the ionic template such as potassium nitrate, potassium sulphate or lithium nitrate at different molar ratios46 or many other parameters depending on the synthesis protocol used. Particles were found to have a diameter ranging from 6 nm to 60 nm.…”

The expected growth in nanomaterial applications could result in increased amounts of nanoparticles entering municipal sewer systems, eventually ending up in wastewater treatment plants and therefore negatively affecting microbial populations and biological nutrient removal. The aim of this study was to ascertain the impact of zinc oxide nanoparticles (nZnO) on the bacterial microbiome of an activated sludge system. A metagenomic approach combined with the latest generation Illumina MiSeq platform and RDP pipeline tools were used to identify and classify the bacterial microbiome of the sludge. Results revealed a drastic decrease in the number of operational taxonomic units (OTUs) from 27 737 recovered in the nZnO-free sample to 23 743, 17 733, and 13 324 OTUs in wastewater samples exposed to various concentrations of nZnO (5, 10 and 100 mg/L nZnO, respectively). These represented 12 phyla, 21 classes, 30 orders, 54 families and 51 genera, completely identified at each taxonomic level in the control samples; 7-15-25-28-20 for wastewater samples exposed to 5 mg/L nZnO; 9-15-24-31-23 for those exposed to 10 mg/L and 7-11-19-26-17 for those exposed 100 mg/L nZnO. A large number of sequences could not be assigned to specific taxa, suggesting a possibility of novel species to be discovered.

“…In recent past, microbial infections have become a global health burden due to emerging and resistant strains of viruses [ 1 ], bacteria [ 2 ], pathogenic fungi [ 3 ] and protozoa [ 4 ] defying clinical treatment. Consequently, this has culminated into prolonged treatment, higher health expenditure, mortality risk, and low life expectancy [ 2 ].…”

Nanoparticles as potential new generation broad spectrum antimicrobial agents

The rapid emergence of antimicrobial resistant strains to conventional antimicrobial agents has complicated and prolonged infection treatment and increased mortality risk globally. Furthermore, some of the conventional antimicrobial agents are unable to cross certain cell membranes thus, restricting treatment of intracellular pathogens. Therefore, the disease-causing-organisms tend to persist in these cells. However, the emergence of nanoparticle (NP) technology has come with the promising broad spectrum NP-antimicrobial agents due to their vast physiochemical and functionalization properties. In fact, NP-antimicrobial agents are able to unlock the restrictions experienced by conventional antimicrobial agents. This review discusses the status quo of NP-antimicrobial agents as potent broad spectrum antimicrobial agents, sterilization and wound healing agents, and sustained inhibitors of intracellular pathogens. Indeed, the perspective of developing potent NP-antimicrobial agents that carry multiple-functionality will revolutionize clinical medicine and play a significant role in alleviating disease burden.
