“…It can be observed that with the increase of the zinc oxide content, the morphology of the nanoparticles changed considerably having nanorods like shapes with variable thicknesses. These results are in agreement with previous reported studies regarding the effect of various dopants on the morphology of the nanoparticles [26][27]. In their study, Ramirez et al [26], determined that the zinc ions concentration is critical to the obtaining ZnO.…”

Dextran coated zinc oxide nanoparticles with various zinc concentration have been developed in this study. Various characterization techniques were used in order to study the physical-chemical properties of the obtained samples. The structure of the samples was investigated using X-Ray diffraction (XRD), while the morphology was studied by scanning electron microscopy (SEM). Information regarding the porosity of the samples were obtained with the aid of Brunauer-Emmett-Teller (BET) method. The results of the physico-chemical characterization depicted the obtaining of a nanocomposite with homogenous and uniform morphology. Furthermore, the antimicrobial activity of the samples was also investigated against Gram-positive bacterial strains (Staphylococcus aureus 0364, Enterococcus faecalis ATCC 29212 and Bacillus subtilis), Gram-negative bacterial strains (Pseudomonas aeruginosa 1397, Escherichia Coli ATCC 259220 and against fungal strain Candida albicans ATCC 10231. The results of the antimicrobial assay showed that the nanocomposites exhibited good inhibitory effects against all the tested microorganisms making them suitable candidates for the further development of antimicrobial agents for biomedical applications.

“…However, incineration at a temperature of 500°C caused a significant increase of nanoparticles dimension (approximately 30 nm). Majumder et al 4 explained the effect of using different salts as a source of zinc. When zinc chloride salt is used, the particles appeared in a hexagonal structure due to the the formation of an intermediate compound Zn5(OH)8Cl2.H2O which is fused with the nanocrystals to give the distinctive hexagonal shape.…”

Alginate biopolymer has been used in the design and development of several wound dressing materials such as (foams, topical formulations, nanofibers, films) due to its favorable properties, such as biocompatibility and non-toxicity. It has been particularly attractive in wound healing applications to date. Additionally, it can be loaded by antibacterial materials such as antibiotics, antibacterial plant extracts and metal nano-oxides. The aim of this study was to design sodium alginate (SA) based zinc oxide (ZnO) nanoparticles as antibacterial film for wound healing applications. The ZnO nanoparticles, with an average particle size of about 16.75 nm, were synthesized by sol-gel method and characterized by scanning electron microscope (SEM) and Fourier-transform infrared spectroscopy (FTIR). They were then incorporated as antibacterial into sodium alginate with different concentration (0, 5, 7.5, 10%). Effectiveness of antibacterial activity was carried out against Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and Gram-positive bacteria (Staphylococcus aureus) to characterize the sample. The prepared ZnO/SA film presents a promising potential for applications as novel wound dressings

“…Till date, numerous semiconductor materials including TiO 2, [ 44 ] CuO, [ 45 ] Fe 2 O 3, [ 46 ] ZnO, [ 47 ] MoS 2, [ 48 ] g‐C 3 N 4, [ 49 ] CdS, [ 50 ] SnO 2, [ 51 ] ZnS, [ 52 ] and SrTiO 3 [ 53 ] have been reported in the literature for the photocatalytic degradation of the colorants. Among these, the semiconductor responsible for the visible‐light driven photocatalytic degradation gains immense popularity over the UV‐driven photocatalytic degradation, owing to the fact that the visible light accounts for more than 50% of solar radiation, whereas UV accounts for just 4%.…”

Magnesium ferrite/sulfur‐doped graphitic nitride (MFO/SCNNS) heterostructure has been developed via sonication‐assisted deposition of zero‐dimensional MFO over the surface of two‐dimensional SCN nanosheets. Additionally, the prepared nanocomposite material has been characterized by several analytical characterization techniques including XRD, Fourier transform infrared (FT‐IR), high‐resolution transmission electron microscopy (HR‐TEM), selected‐area electron diffraction (SAED), energy‐dispersive spectrometry (EDS), Brunauer–Emmett–Teller (BET), vibrating sample magnetometer (VSM), UV–Vis. spectroscopy, electron spin resonance(ESR), and X‐ray photoelectron spectroscopy (XPS) which indicated the existence of strong interfacial interactions via heterojunction formation between MFO and SCNNS. The as prepared nanocomposite, especially MFO:SCNNS (1:1) (having 1:1 mass ratio of MFO to SCNNS), offered impressive photo‐response for the complete degradation of Erythrosine B and Indigo Carmine within 30 min under direct solar light irradiation. The enhanced photoactivity of the MFO:SCNNS (1:1) was also confirmed by the photoluminescence, photocurrent and electrochemical impedance spectroscopy. The Mott–Schottky analysis also depicts the formation of p‐n heterojunction at the interface of MFO and SCNNS, responsible for the enhanced photoactivity. Additionally, the degradation process has also been studied using mass spectrometry, UV–Vis, and ESR spectral analysis. The trapping experiments were also conducted to confirm the formation of active radical species during the photodegradation reaction. Furthermore, the nanocomposite photocatalytic material offered excellent stability and reusability and thus can serve as an effective candidate for environmental remediation application such as real waste water treatment.
