The biosynthesis of ZnO nanoparticles and synthesis of chitosan- ZnO nanoparticles were studied. The aims of this research were biosynthesis of ZnO nanoparticles, synthesis of chitosan-ZnO nanoparticles, its characterization and, used as an antibacterial agent of Escherichia coli. ZnO nanoparticles were biosynthesized by reacting with ethanolic extract of guava seeds leaves (Psidium guajava L.) and zinc acetate dihydrate solution. Chitosan-ZnO nanoparticles were synthesized by the heating method. ZnO nanoparticles and chitosan-ZnO nanoparticles were characterized by FTIR spectroscopy and X-ray diffraction, respectively. The suspension of chitosan-ZnO nanoparticles was used as an antibacterial agent with a paper disk method. The result showed that the Zn-O group at ZnO nanoparticles was detected at a wavenumber 615.29 and 673.16 cm-1 The crystallite size of ZnO nanoparticles was 1.43 nm. The wavenumber of 617-655 cm-1 is the Zn-O group at the structure of the chitosan-ZnO nanoparticle. The average of diameter inhibition zone of chitosan-ZnO nanoparticles (1:2) at concentration 0.25 and 0.5 % (w/v) to Escherichia coli was 15.7 ± 1.0 and 18.3 ± 0.4 mm respectively.

In this work, we have implemented an eco-friendly method for synthesis of zinc oxide nanoparticles (ZnO NPs) using potato extracts (Solanum tuberosum) as the natural bio-reductants and stabilizing agent. Meanwhile the zinc nitrate octahydrate (Zn[NO3] 2.6H2O) and ammonium hydroxide (NH4OH) were used as the precursor of ZnO NPs. The sediment of Zn(OH)2 was separated from the solvent using centrifuge, and further calcinated at the temperature of 500ºC so that formed ZnO nanoparticles. SEM micrograph of ZnO NPs shows the hexagonal shapes with particles size around 50–100 nm. The XRD spectra confirms that ZnO NPs exhibited well crystalline nature, however, there were impurity peaks caused by the potato extracts addition. From the FTIR analysis, we obtained the existence of another chemical compounds, denoting the presence of stabilizing and reducing agent from potato extract. Keywords: ZnO nanoparticles, green synthesis, antibacterial and active packaging

“…The researchers used the metal oxide nanoparticles as the modi er agent of chitosan such as ZnO (Dananjaya et al, 2018;Fatoni et al, 2020b;Fatoni et al, 2020a;, CuO nanoparticles (Fatoni et al, 2020), and AgO nanoparticles (Hajji et al, 2019) because the primary amine groups of chitosan can be reacted with metal oxide nanoparticles (Usman et al, 2012;Haldorai and Shim, 2013;Abdelhady, 2012). Application of chitosan modi ed metal oxide nanoparticles was studied by researchers such as antibacterial (Dananjaya et al, 2018;Fatoni et al, 2020b;Fatoni et al, 2020a;Fatoni et al, 2020;Hajji et al, 2019), dye degradation (Preethi et al, 2020), adsorbent (Muinde et al, 2020) and analytical sensor (Nainggolan et al, 2020).…”

The synthesis of film chitosan- ZnO nanoparticles-CTAB were studied. The aims of this research were synthesis of the film chitosan-ZnO nanoparticles-CTAB, its characterization and, application of the film chitosan-ZnO nanoparticles-CTAB as an antibacterial of Staphylococcus aureus. The film of chitosan-ZnO nanoparticles-CTAB was synthesized by the casting method and characterized by FTIR spectroscopy and X-ray diffraction, respectively. The film of chitosan-ZnO nanoparticles-CTAB was used as an antibacterial agent with the agar disk diffusion method. The result showed that the Zn-O group at the film of chitosan-ZnO nanoparticles-CTAB was detected at a wavenumber between 578-619 cm-1. The band at 2852.72-2854.65 cm-1 is the band of C-H groups in the film of chitosan-ZnO nanoparticles-CTAB. The effect of ZnO nanoparticles-CTAB changed of the physical structure of chitosan. The average of the inhibition zone in the film of chitosan-ZnO nanoparticles-CTAB I, II and III was 10.37 ± 0.55, 11.31± 1.27 and 10.38 ± 0.24 mm respectively.
