“…However, its biocompatibility with biological organisms is a major concern. ZnO NPs have been reported to exert cytotoxic effects on various cell lines 17,31,37 . Nevertheless, the cytotoxic effects are highly dependent on many parameters, including the characteristics of NPs (shape and size), synthesis methods, and the type of cell line used 2,54 .…”

This study aims to utilize the cell-biomass (CB) and supernatant (CFS) of zinc-tolerant Lactobacillus plantarum TA4 as a prospective nanofactory to synthesize ZnO NPs. The surface plasmon resonance for the biosynthesized ZnO NPs-CFS and ZnO NPs-CB was 349 nm and 351 nm, respectively, thereby confirming the formation of ZnO NPs. The FTIR analysis revealed the presence of proteins, carboxyl, and hydroxyl groups on the surfaces of both the biosynthesized ZnO NPs that act as reducing and stabilizing agents. The DLS analysis revealed that the poly-dispersity indexes was less than 0.4 for both ZnO NPs. In addition, the HR-TEM micrographs of the biosynthesized ZnO NPs revealed a flower-like pattern for ZnO NPs-CFS and an irregular shape for ZnO NPs-CB with particles size of 291.1 and 191.8 nm, respectively. In this study, the biosynthesized ZnO NPs exhibited antibacterial activity against pathogenic bacteria in a concentration-dependent manner and showed biocompatibility with the Vero cell line at specific concentrations. Overall, CFS and CB of L. plantarum TA4 can potentially be used as a nanofactory for the biological synthesis of ZnO NPs.

“…Moreover, the synthesized ZnONPs exhibited potent antimicrobial activity compared to the standard antimicrobials (amoxicillin/clavulanic acid and nystatin). Previous reports have demonstrated the antimicrobial activity of ZnONPs against several bacterial and fungal species; P. aeruginosa (Jayaseelan et al ; Rajabairavi et al ), Enterococcus sp., S. aureus and P. mirabilis (Chauhan et al ), E.coli and B. subtilis (Balraj et al ), S. aureus and E. coli (Khatami et al ), B. subtilis , E. coli and P. fluorescens (Jiang et al ), H. pylori (Saravanan et al ), A. flavus (Jayaseelan et al ), A. alternata , A. niger , B. cinerea , F. oxysporum and P. expansum (Jamdagni et al ), B. subtilis , S. aureus , E. faecalis , E. coli , P. aeruginosa , K. pneumoniae , C. albicans and C. tropicalis (Abd Elkodous et al ; Gao et al ). Our results further showed that the estimated MIC value of the synthesized ZnONPs against the tested microbes was in the range of 50–100 µg ml −1 .…”

Aims Zinc oxide nanoparticles (ZnONPs) were successfully synthesized using the culture filtrate of the endophytic fungus Alternaria tenuissima as a rapid, eco‐friendly and cost‐effective method. Methods and Results The rapid synthesis of ZnONPs was completed after 20 min as confirmed by UV–Vis spectroscopy. The synthesized ZnONPs showed a single‐phase crystalline structure. Dynamic light scattering analysis showed that the synthesized ZnONPs were monodispersed and the recorded polydispersity index value was 0·311. Zeta potential value of –23·92 mV indicated the high stability of ZnONPs. Transmission electron microscope revealed the spherical shape and the mean particle size was 15.45 nm. Functional groups present in the prepared samples of ZnONPs were confirmed by Fourier transform infrared spectroscopy. Additionally, the biological activities of in vitro antimicrobial, anticancer, antioxidant as well as the photocatalytic activities were evaluated. ZnONPs showed broad spectrum of antimicrobial potential against all the tested plant and human pathogens. Based on the MTT assay, ZnONPs inhibited the proliferation of normal human melanocytes, human breast and liver cancer cell lines with IC50 concentrations of 55·76, 18·02 and 16·87 µg ml−1. ZnONPs exhibited promising antioxidant potential with 50% inhibitory concentration of 102·13 µg ml−1. Moreover, ZnONPs showed efficient degradation of methylene blue dye. Conclusions The synthesized ZnONPs showed promising activities that can be better explored in the near future for many medical, agricultural and industrial applications. Significance and Impact of the Study This study suggests a new and alternate approach with the excellent biotechnological potentiality for the production of ZnONPs which could open up the way for the industrial manufacture of nanoparticles using microbial platforms.

“…In addition, the eco-friendly method for synthesis of nanomaterials can also be achieved by reducing the required process temperature, using microwave or ultrasonic waves [7][8][9][10][11][12][13][14][15][16][17][18]. In recent years a number of nanoparticles have been prepared using fungi, bacteria, actinomycetes, and enzymes [19][20][21][22][23] and also have been used as many plant extracts such as camellia sinensis, neem, coriandrum, ocimum sanctum, nelumbo lucifera [24][25][26]. Recently, researchers have been able to achieve the biosynthesis of nanoparticles by any part of the plant parts such as leg, leaves, roots, flowers, buds, and seeds [27].…”

Nanoporous TiO2 anatase was environment-friendly prepared using coffee husk extract (CHE) as bio-template instead of hazardous chemicals and solvents and ultrasonic waves. Caffeine and caffeic acid were found to be the main compounds in CHE to modify the morphology of TiO2. The properties of as-prepared titanium dioxide particles were determined by different characterization techniques. The results demonstrate the formation of a meso/macro-porous channel consisting of small TiO2 particles (8–10 nm). The as prepared green nanoparticles exhibited improved photocatalytic activity for the degradation of organic water pollutants with good recyclability. The enhancement in efficiency of green nanoporous TiO2 can be attributed to higher surface area and the presence of more active adsorption sites inside the pores. The current research provides for a low cost, safe, and eco-friendly way to produce efficient photocatalysts for remediation of polluted water.
