“…The deltamethrin interaction with Zn-Fe LDH was verified when the OH vibration mode peak changed from 3477 to 3396 cm -1 [ 44 , 52 ]. The creation of hydrogen bonds between H bond donor oxygen atoms and LDH layers is verified by the conjugation of deltamethrin with Zn-Al-GA LDH, as shown by the rise in intensity and shifting of peaks in the FT-IR spectra of Zn-Al-GA LDH/deltamethrin [ 35 , 53 ]. The appearance of some peak vibration modes at 1643 and 1734 cm -1 decreases the intensity of vibration peaks at 457 and 540 cm -1 in the FT-IR spectrum of deltamethrin/Fe-oxide, indicating the interaction of deltamethrin with Fe-oxide and the conversation of magnetite to hematite Fe-oxide, as well as the disappearance of a peak at 686 cm -1 [ 54 , 55 ].…”

“…The interaction of deltamethrin with Fe-oxide resulted in the conversion of the magnetite form of Fe-oxide to the hematite form of Fe-oxide. As a result, certain peaks had increased intensity (e.g., 33.2˚, 49.58˚, and 54.13˚), while others had reduced intensity (e.g., 35.69˚, 62.59˚). This change from magnetite to hematite happened because the magnetite form was less stable, causing agglomeration via magnetostatic interaction and oxygen adsorption (Fig 2).…”

New insight on some selected nanoparticles as an effective adsorbent toward diminishing the health risk of deltamethrin contaminated water

Deltamethrin is a widely used insecticide that kills a wide variety of insects and ticks. Deltamethrin resistance develops as a result of intensive, repeated use, as well as increased environmental contamination and a negative impact on public health. Its negative impact on aquatic ecology and human health necessitated the development of a new technique for environmental remediation and wastewater treatment, such as the use of nanotechnology. The co-precipitation method was used to create Zn-Fe/LDH, Zn-AL-GA/LDH, and Fe-oxide nanoparticles (NPs), which were then characterized using XRD, FT-IR, FE-SEM, and HR-TEM. The kinetic study of adsorption test revealed that these NPs were effective at removing deltamethrin from wastewater. The larval packet test, which involved applying freshly adsorbed deltamethrin nanocomposites (48 hours after adsorption), and the comet assay test were used to confirm that deltamethrin had lost its acaricidal efficacy. The kinetics of the deltamethrin adsorption process was investigated using several kinetic models at pH 7, initial concentration of deltamethrin 40 ppm and temperature 25°C. Within the first 60 min, the results indicated efficient adsorption performance in deltamethrin removal, the maximum adsorption capacity was 27.56 mg/L, 17.60 mg/L, and 3.06 mg/L with the Zn-Al LDH/GA, Zn-Fe LDH, and Fe Oxide, respectively. On tick larvae, the results of the freshly adsorbed DNC bioassay revealed larval mortality. This suggests that deltamethrin’s acaricidal activity is still active. However, applying DNCs to tick larvae 48 hours after adsorption had no lethal effect, indicating that deltamethrin had lost its acaricidal activity. The latter result corroborated the results of the adsorption test’s kinetic study. Furthermore, the comet assay revealed that commercial deltamethrin caused 28.51% DNA damage in tick cells, which was significantly higher than any DNC. In conclusion, the NPs used play an important role in deltamethrin decontamination in water, resulting in reduced public health risk. As a result, these NPs could be used as a method of environmental remediation.

“…In this context, Nir et al [127] modified stainless steel surfaces with peptides‐based coatings to reduce the adhesion of biofilm‐forming bacteria especially P. aeruginosa and B. licheniformis without affecting the physiochemical properties of milk. Some other approaches include the use of bacteriocins [128], bacteriophages (polyvalent phage CoNShP‐3) [129], antimicrobial peptides (melittin) [130], enzyme‐based strategy (protease, α‐amylase, DNase, lipase, cellulase, and enzymes) [131], metallic cations (Zn 2+ ) [132], peptide‐coated surfaces [127], nanocomposite like zinc–aluminum‐layered double hydroxide intercalated with gallic acid as a chelating agent (Zn‐Al LDH/GA) [133], and so forth for inactivation and removal of mature biofilms [124].…”

Microbial biofilm: A matter of grave concern for human health and food industry

Pathogenic microorganisms have adapted different strategies during the course of time to invade host defense mechanisms and overcome the effect of potent antibiotics. The formation of biofilm on both biotic and abiotic surfaces by microorganisms is one such strategy to resist and survive even in presence of antibiotics and other adverse environmental conditions. Biofilm is a safe home of microorganisms embedded within self‐produced extracellular polymeric substances comprising of polysaccharides, extracellular proteins, nucleic acid, and water. It is because of this adaptation strategy that pathogenic microorganisms are taking a heavy toll on the health and life of organisms. In this review, we discuss the colonization of pathogenic microorganisms on tissues and medically implanted devices in human beings. We also focus on food spoilage, disease outbreaks, biofilm‐associated deaths, burden on economy, and other major concerns of biofilm‐forming pathogenic microorganisms in food industries like dairy, poultry, ready‐to‐eat food, meat, and aquaculture.
