“…As shown in Figure 1(a), the calculated average hydrodynamic diameter based on DLS analysis shows aggregates ZnO nanoparticles size that are approximately similar value which are 168 nm, 170 nm, and 180 nm at 2 minutes, 4 minutes and 6 minutes respectively. The slight increase in the aggregates nanopar- [16]. At 10 minutes of microwave irradiation time, the aggregates nanoparticles size increased to 225 nm almost 34 % from the size at 2 minutes of microwave irradiation time.…”

“…Gum arabic is a hydrophilic, biocompatible, non-toxic and ecofriendly polymer [15]. When the gum arabic is adsorbed on the particle surface, steric hindrance, bridging or charge-patch are formed to stabilize the particles [16]. To the author's best knowledge, there appear to be no published studies on the microwave-assisted synthesis of ZnO nanoparticles using gum arabic as stabilizing agent.…”

“…Different microwave irradiation times will synthesize different ZnO nanoparticles size and morphology [17]. Several studies had revealed the morphology changes with microwave irradiation time forming different types of complex nanostructures [15,16]. Although the synthesis process using stabilizing agent such as (sodium di-2-ethylhexyl-sulfosuccinate (AOT), it was difficult to control the growth under longer microwave irradiation time.…”

The conventional heating methods of nanoparticle synthesis regularly depend on the energy inputs from outer heat sources that resulted high energy intake and low reaction competences. In this paper ZnO nanoparticles stabilized with gum arabic are synthesized using precipitating method assisted by simple and cost effective microwave heating technique. The objective of this work is to investigate the effect of microwave irradiation time towards ZnO nanoparticles morphology and size. The effect of microwave irradiation time has been investigated at 2, 4, 6, and 10 minutes. Dynamic Light Scattering (DLS) was employed to measure the size of ZnO nanoparticles. Ultraviolet–Visible spectroscopy (UV-vis), Fourier-Transform Infrared Spectroscopy (FTIR) and X-Ray Diffraction (XRD) were used for the characterization of the ZnO nanoparticles. UV-vis absorption spectrum was found in the range of 350 nm indicating the absorption peak of ZnO nanoparticles. FTIR spectra showed peaks range from 424 to 475 cm–1 which indicating standard of Zn–O stretching. The presence of (100), (002), and (101) planes were apparent in the XRD result, indicating the crystalline phase of ZnO nanoparticles. The increase in the microwave irradiation time affected the processes of nucleation and crystal growth promoted larger ZnO nanoparticles size. Microwave irradiation time at 2 minutes was selected as the best microwave irradiation time for smallest ZnO nanoparticles averaging about 168 nm sizes based on DLS analysis.

The present study deals with the development of novel ZnO microparticle‐loaded chitosan/poly(vinyl alcohol)/acacia gum nanosphere‐based nanocomposite thin films through electrospraying and evaluation of their potential use in wound healing applications for skin. ZnO microparticles were synthesized and used as bioactive agents. Morphology, size distribution, structure, and dispersion of the synthesized ZnO microparticles were analyzed by scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy (TEM). ZnO microparticles were incorporated into the ternary nanocomposite films by electrospraying technique. Thermogravimetric analyses reveal that incorporation of ZnO microparticles into the nanocomposite structure improves the thermal stability. Mechanical analyses show that tensile strength reaches to the maximum value of 12.75 MPa with 0.6 wt % ZnO content. SEM and TEM micrographs demonstrate that the nanocomposite films consist of nanospheres with nanocapsular structures whose sizes are mostly between 250 and 550 nm. Viability tests established prevailing cellular performance of the fibroblasts on 0.6 wt % ZnO microparticle‐loaded nanocomposite films with a viability percentage of 160% compared to the control group. © 2019 Wiley Periodicals, Inc.
