“…Furthermore, the FS NPs cytotoxic affect on COLO 205 cells was associated with the loss of membrane integrity and chromatin condensation that have a great role in the induction of apoptosis as evidenced by acridine orange/ ethidium bromide staining. 283 On the other hand, it was also demonstrated that AgNO 3 and metal-based nanoparticles (AgNPs) had strong potential for cytotoxic, antiproliferative, and apoptotic property in H-ras 5RP7 cells and cervical cancer, respectively. 284,285 Biosynthesized nanosilver from the extract of Pterocladiella capillacea (11.4±3.52 nm) and P. aeruginosa (13-76 nm) showed great potential against human hepatocellular carcinoma (HepG2) cell lines and human cervical cancer cells (HeLa), respectively.…”

Silver nanotechnology has received tremendous attention in recent years, owing to its wide range of applications in various fields and its intrinsic therapeutic properties. In this review, an attempt is made to critically evaluate the chemical, physical, and biological synthesis of silver nanoparticles (AgNPs) as well as their efficacy in the field of theranostics including microbiology and parasitology. Moreover, an outlook is also provided regarding the performance of AgNPs against different biological systems such as bacteria, fungi, viruses, and parasites (leishmanial and malarial parasites) in curing certain fatal human diseases, with a special focus on cancer. The mechanism of action of AgNPs in different biological systems still remains enigmatic. Here, due to limited available literature, we only focused on AgNPs mechanism in biological systems including human (wound healing and apoptosis), bacteria, and viruses which may open new windows for future research to ensure the versatile application of AgNPs in cosmetics, electronics, and medical fields.

These protein molecules act as a surfactant to attach on the surface of the nanoparticles which keep away from the internal agglomeration of the AuNPs and increase their stabilization during the synthesis reaction.…”

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.

Nanotechnology has attracted the attention of researchers from different scientific fields because of the escalated properties of nanomaterials (NMs) compared with the properties of macromolecules. NMs can be prepared through different approaches involving physical and chemical methods. The development of NMs through plantbased green chemistry approaches is more advantageous than other methods from the perspectives of environmental safety, animal, and human health. The biomolecules and metabolites of plants act as reducing and capping agents for the synthesis of metallic green NMs. Plant-based synthesis is a preferred approach as it is not only cost-effective, easy, safe, clean, and eco-friendly but also provides pure NMs in high yield. Since NMs have antimicrobial and antioxidant potential, green NMs synthesized from plants can be used for a variety of biomedical and environmental remediation applications. Past studies have focused mainly on the overall biogenic synthesis of individual or combinations of metallic NMs and their oxides from different biological sources, including microorganisms and biomolecules.Moreover, from the viewpoint of biomedical applications, the literature is mainly focusing on synthetic NMs. Herein, we discuss the extraction of green molecules and recent developments in the synthesis of different plant-based metallic NMs, including silver, gold, platinum, palladium, copper, zinc, iron, and carbon. Apart from the biomedical applications of metallic NMs, including antimicrobial, anticancer, diagnostic, drug delivery, tissue engineering, and regenerative medicine applications, their environmental remediation potential is also discussed. Furthermore, safety concerns and safety regulations pertaining to green NMs are also discussed.
