“…Bacterial resistance against existing drugs has directed to severe health concerns all over the world [45]. Our present findings confirm that B. monnieri is very effective against MDR-UTI and RTI clinical isolates, where majority of the commercially available antibiotics are unable to treat those.…”

“…which accordance to an earlier study of Phull et al(2016) on synthesized AgNPs using plant extract of Bergenia ciliata. 62 In overall, plant biomolecules such as phenols and flavonoids are nucleophilic in nature due to the presence of aromatic rings and responsible for the chelating potential. 63 Binding of these biomolecules with metal is confirmed by measuring their content in nanoparticles.…”

In this work, biosynthesis potentials of Dracocephalum kotschyi leaf extract for the production of gold nanoparticle (AuNPs) were studied, and the biological (catalytic, antibacterial, antioxidant, and anticancer) activities of studied AuNPs were evaluated. Different analytical techniques including UV–visible spectroscopy, X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), energy dispersive X‐ray analysis, and transmission electron microscopy (TEM) were used for the characterization of AuNPs. Moreover, Different testing methods were used for evaluating biological activities of biosynthesized AuNPs. The formation of AuNPs was confirmed by color change and UV–visible spectroscopic analysis. Field emission (FE)‐SEM and TEM images were used to characterize phytosynthesized AuNPs which were predominantly spherical in shape with size in the range of 5–21 nm. These spherical NPs were found to be 39.79 ± 5 nm in size as determined by dynamic light scattering particle size analyzer. XRD pattern confirms the crystalline nature of the biosynthesized nanoparticles. The phytoconstituents involved in the reduction and stabilization of nanoparticles have been identified using FTIR spectra. The phytosynthesized AuNPs showed effective antioxidant, antibacterial and catalytic reduction activities. Furthermore, they have inhibited H1229 and MCF‐7 cancer cell lines proliferation in a dose‐dependent manner. These results have supported that D. kotschyi leaf extract was very efficient for the synthesis of AuNPs, and synthesized NPs showed enhanced biological activities which make them suitable for biomedical applications. © 2018 Wiley Periodicals, Inc.

“…Organically synthesized compounds which are used for disinfection have some disadvantages, including toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide NPs is increasing. Biologically synthesized and capped with special compounds (proteins and polysaccharides), SeNPs have antimicrobial activity [70]. These SeNPs have an inhibitory effect on many microorganisms such as bacteria, fungi, and nematodes.…”

Biosynthesis is an eloquent, safe, biocompatible, eco-friendly, and recyclable way of preparing selenium nanoparticles (SeNPs). Selenium occurs in multiple oxidation states, for example, +6, +4, 0, or −2. Selenium (Se) is an essential trace element with a very narrow margin between the lowest acceptable levels of intake and toxicity. Selenium is an essential trace element required for all living organisms. Despite its essentiality, selenium is a potentially toxic element to natural ecosystems due to its bioaccumulation potential that is why it is biologically available in the environment. Selenium is a trace element commonly found in materials of the earth’s crust, and it is essential for humans, animals, and plants. Oxyanions of selenium, that is selenite and selenate, are biologically available. Selenium in the form of selenate ion (SeO42−) is more toxic to most organisms than selenite (SeO32−). Contrarily, elemental selenium (Se0) is inOsoluble and less toxic in comparison to other forms of selenium. Nanoselenium (Se0) in the range of 100–500 nm has similar bioavailability to other forms of selenium into plants, animals, humans, and microorganisms. Biologically synthesized SeNP has many biological applications in the field of medical and pharmaceutical research to combat threats to human health. Biogenic SeNPs have anticancer (cytotoxic) activity, antioxidant activity, and antimicrobial activity. Researches are going on with special interest of SeNPs. Conjugation of antibiotics with SeNPs enhances their anticancer efficacy. SeNPs have also applications in nanobiosensors and environmental remediation.
