“…Therefore, any substance with potentials to inhibit PK enzymes are of great attention in the field of cancer research [57]. PK phosphorylation has played an important role in the formation of hyphae in Streptomyces fungal strain and same mechanism is used to evaluate the PK inhibition potentials and is utilized to study medicinal compounds for determining PK inhibition [5]. The PK inhibition activity was done via disc diffusion method using different doses of ZnONPs ranging from 31.25−1000 µg/mL.…”

This study attempts to obtain and test the bioactivities of leaf extracts from a medicinal plant, Geranium wallichianum (GW), when conjugated with zinc oxide nanoparticles (ZnONPs). The integrity of leaf extract-conjugated ZnONPs (GW-ZnONPs) was confirmed using various techniques, including Ultraviolet–visible spectroscopy, X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, energy-dispersive spectra (EDS), scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy. The size of ZnONPs was approximately 18 nm, which was determined by TEM analysis. Additionally, the energy-dispersive spectra (EDS) revealed that NPs have zinc in its pure form. Bioactivities of GW-ZnONPs including antimicrobial potentials, cytotoxicity, antioxidative capacities, inhibition potentials against α-amylase, and protein kinases, as well as biocompatibility were intensively tested and confirmed. Altogether, the results revealed that GW-ZnONPs are non-toxic, biocompatible, and have considerable potential in biological applications.

The potent biocontrol agent Trichoderma interfusant (Fu21) derived by protoplast fusion of mycoparasitic T.virens NBAII Tvs12 and multistress (fungicides and abiotic stress) tolerant T. koningii MTCC796. The chitin‐induced exometabolites harvested by culturing the diverse and stress tolerant Trichoderma fusant (Fu21) and utilized for synthesis of green silver nanoparticles (Ag‐NPs). Green Ag‐NPs characterized for size (62.6 nm in PSA), shape (spherical with 59.66 ± 4.18 nm under SEM), stability (51.2 mv as ZETA) and purity (3.40 ke V peak corresponded to the binding energy of silver under EDAX). A Fourier transform infrared spectroscopy exhibited electromagnetic spectra of various functional groups of exometabolites conforming the synthesis of green Ag‐NPs. We investigated novel route and mechanism of mycelial degradation at minimum inhibitory concentration (MIC) of green nanoformulation (20 μg Ag.ml−1) to restrain phytopathogen Sclerotium rolfsii. The antifungal action of green Ag‐NPs on MIC at 3 DAI elevated the mycelial cell membrane leakages (sugars and proteins), lipid peroxidation, depressed the respiratory chain dehydrogenase activity and destroyed the structure of S. rolfsii mycelia (SEM morphology) which cause phytopathogen to die. The use of green Ag‐NPs as antifungal agent is considered to be eco‐friendly resource, alternate to fungicides and cost‐effective means to diminish phytopathogen S. rolfsii causing stem rot in groundnut. Further, bioefficacy of green Ag‐NPs against S. rolfsii may be tested under field condition in groundnut rhizosphere which proved sustainability and it's advancement towards greener chemistry.

“…Helan et al [23] prepared the NiO nanoparticles with the help of phytoconstituents present in the neem leaf and observed their antibacterial activity, which was concentration-dependent. In their study, [24] also synthesized NiO nanoparticles by an environmentally-benign synthetic method using Geranium wallichianum as reducing and capping agent. The NiO nanoparticles in their study were of 21 nm size and nanoparticles showed showed antibacterial potential against different bacterial strains at different concentrations (700-21.875 µg/ml).…”

Bacterial resistance to antibiotic treatment is a major emerging clinical and public health issue across the globe. Advancements in the field of metal oxide nanomaterials in the last few years have improved the potential of metal oxides in different applications. Metal oxides, of which, nickel oxide (NiO) is one, also possess antibacterial activities. This investigation was planned to synthesize NiO nanoparticles to study their antibacterial potential in comparison with bulk NiO and standard antibiotics at different concentrations. Synthesis and characterization of NiO nanoparticles was done by standard procedures. The antibacterial potentials of different compounds were determined at different concentrations against S. aureus and E. coli. The diameter of zone of inhibition showed that the antibacterial effect of NiO nanoparticles against S. aureus was better than E. coli at the same concentration. The concentration-dependent effect of NiO nanoparticles was observed from 0.125 to 128 µg/ml. The effect of NiO nanoparticles was markedly better than bulk NiO at all concentrations. Tetracycline and gentamicin did not show effect below 1.0 µg/ml and 2.0 µg/ml, respectively. The activity index and fold increase of NiO nanoparticles were both higher than 1 and positive, with respect to tetracycline, gentamicin and bulk NiO against S. aureus and E. coli at all the tested concentrations. In conclusion, the NiO nanoparticles seemed to be a more potent antibacterial agent than their bulk form, tetracycline and gentamicin, and in future, their applications may be extended in biomedical field and other areas to reduce microbial infections and incidences of antibacterial resistance.
