Composite nanomaterials of ZnO/chitosan oligosaccharide (ZnO/COS) and ZnO/chitosan oligosaccharide iodine (ZnO/CTS‐I2) were expected to have effective antimicrobial effects due to the synergistic effects of the components. In this work, we present a method to synthesize ZnO nanoparticles with size of 12.3‐15.0 nm stabled in COS with low molecular weight (Mw) 3,321 g/mol and COS‐I2 complex by precipitation of Zn2+ with NaOH at pH 9, and then ultrasonic treatment to form ZnO nanoparticles. The UV‐Vis spectra of ZnO/COS and ZnO/COS‐I2 composite nanomaterials both appeared absorption peaks typical for surface plasmon resonances of ZnO nanoparticles in solution at 372 and 370 nm, respectively. X‐ray diffraction (XRD) patterns confirmed the formation of ZnO/COS‐I2 with wurtzite crystal structure characterized in both materials. The FT‐IR spectra of COS, COS‐I2, nano ZnO/COS, and nano ZnO/COS‐I2 were measured. The characteristic peaks for the bonding vibrations of –OH and –NH2 groups of ZnO/COS and ZnO/COS‐I2 shifted to a larger wavenumber than that of COS. The prepared ZnO/COS and ZnO/COS‐I2 nanocomposite materials may have potential for application as antibacterial agents used in medicine, food, and agricultural product preservation, control of harmful microorganisms on plants, and plant growth promotion.

“…Therefore, the mass drop curve is clearly obtained by the organic degradation/decompositions while the ZnONPs remained stable with their lattice orientations, and hence, the mass drop does not start at 100% [53]. Figure 8b shows the DSC curve of the synthesized ZnONPs, which revealed endothermic peaks at around 285 • C. The broad peak at around 285 • C is probably due to the loss of chemically adsorbed volatile organic molecules and the formation of ZnONPs [54,55].…”

Nanotechnology and nanomaterials have gained much attention in recent years due to their remarkable features. Among nanoparticles, photocatalytic material, such as zinc oxide, have shown tremendous applications in each and every field of science. In the present research, investigators have synthesized zinc oxide nanoparticles (ZnONPs) using Scallion’s peel extract. ZnONPs were both spherical and rod-shaped, where the size for spherical particles was 40–100 nm and rod-shaped, particles size was more than 200 nm as confirmed by microscopic techniques. The typical trademark bands of ZnONPs at 400–800 cm−1 were revealed by infrared spectroscopy, which also showed bands of carbonyl and hydroxyl groups. The hydrodynamic size by particle size analyzer (PSA) shows a size near about 200 nm in diameter. Furthermore, the synthesized ZnONPs were used to assess their potential as a micronutrient for the plant and nano adsorbent for the removal of antibiotics (ampicillin) and methylene blue dye from the simulated wastewater. The antibiotic and dye removal were observed under UV light and visible light against contact time. In comparison to control seeds, seeds grown with ZnONPs have shown better germination and seedling. It could be concluded that ZnONPs acted as an important nanosized source of nutrition for agricultural applications. Thus, the effect of ZnONPs has been proven as a nano-based nutrient source for agricultural purposes. The remediation study found that remediation of both ampicillin and methylene blue dye was efficient under UV light under similar experimental parameters from the simulated wastewater by the ZnONPs.

Recently, there has been a lot of interest in the fabrication of metal oxide nanoparticles (NPs) due to the growing importance of developing recyclable assets, affordable methods, sustainable substances, and safe compounds. The current study demonstrates the environmentally friendly fabrication of ZnO NPs through the use of an aqueous extract derived from discarded eggshells. The analysis of ZnO NPs involved the use of UV, x‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FT‐IR), and field‐emission scanning electron microscopy (FE‐SEM) with EDX techniques. The anti‐germs effects of fabricated NPs on pathogens were investigated using the agar diffusion technique. The cell‐damaging effects were assessed using the MTT assay, whereas the photodecomposition capacity was examined with Congo red and methylene blue dye. X‐ray diffraction analysis revealed the existence of tetragonal crystal morphology. The generated ZnO NPs have a crystallite size of 17.6 nm. According to FE‐SEM examination, the created sample's average grain size has been determined to be between 20 and 30 nm. The sustainable production of ZnO NPs showed remarkable anti‐germs properties against human pathogenic organisms and had good efficacy in damaging Osteosarcoma cell lines (MG‐63) during the experiment. Additionally, it emerged that the manifestation of remarkable catalytic efficiency fell by 78.1% after 60 min for methylene blue. Based on the findings, it has been determined that sustainable production of ZnO NPs shows great potential across multiple fields such as anti‐germs, anti‐proliferative, and photodecomposition properties.
