“…Their conclusions were that the NPs can interact with the aquatic animals' cell membranes, thus leading to disruption in the membrane potential that is associated with the ion-efflux disturbance. The study is of particular importance as the accumulation/effect on the planktonic organisms could affect the entire aquatic ecosystem, as those organisms represent the primary producers in those systems [120]. The findings of Odeyemi et al [91] regarding the toxicity of Ag NPs on rats could be correlated with the work of El-Maksoud et al [123], who demonstrated that chemically-obtained AgNPs at 50 mg/kg body weight (b.w.)…”

“…In terms of phytotoxicity, silver NPs (spherical, 15 nm, obtained by using the aqueous extract of Veronica officinalis L.) were proven to be non-toxic (in the concentration range of 0.0009-0.0675 mg/mL) towards Linum flavum and Lepidium sativum seeds [124], while the application of magnetite NPs (semi-spherical, 29.8 nm, obtained by using a Fumaria officinalis L. aqueous extract) led to growth reduction and significant changes in the total phenol, total flavonoid content, and antioxidant enzymes' activity of the aquatic plant Azolla filiculoides (at 0.5-10 mg/L concentrations) [125]. Among the presented studies, Jenifer et al [120] comparatively studied the toxicity of silver nanoparticles and silver ions on invertebrate and vertebrate aquatic animals. By using spherical Ag NPs with dimensions between 10 and 50 nm, they studied their effects on the water flea (Ceriodaphnia cornuta), unicellular ciliates (Paramecium sp.…”

Phytosynthesized Metallic Nanoparticles—between Nanomedicine and Toxicology. A Brief Review of 2019′s Findings

Phytosynthesized nanoparticles represent a continuously increasing field of research, with numerous studies published each year. However, with the emerging interest in this area, the quality of the published works is also continuously increasing, switching from routine antioxidant or antimicrobial studies on trivial microbial lines to antibiotic-resistant strains or antitumoral studies. However, this increasing interest has not been not reflected in the studies regarding the toxicological effects of nanoparticles (NPs); this should be a subject of greatest interest, as the increasing administration of NPs in general (and phytosynthesized NPs in particular) could lead to their accumulation in the environment (soil, water and living organisms). The present review aims to present the most recent findings in the application of phytosynthesized NPs as antimicrobial and antitumoral agents, as well as the results regarding their toxicological potential.Materials 2020, 13, 574 2 of 32 in terms of their toxic potential towards target organisms (leading to their proposal as antimicrobial [4], antiviral [5] or cytogenotoxic agents [6]), their possible negative toxicity has not been thoroughly established. The present review aims to present the advances that have been recorded in the last year in the area of phytosynthesized nanoparticle applications and toxicity studies, as well to underline the shortcomings of the encountered approach. The literature review survey was performed on multiple databases (Scopus, Web of Science, ScienceDirect, SpringerLink, PubMed) and used the main keywords "nanoparticles" and "extract" (as the term "phytosynthesis" was not adopted by all the authors). From the returned results, only the works that were published in the last year (2019) were selected. Furthermore, a supplementary selection was performed by using keywords as "antimicrobial," "cytotoxicity," and "toxicology" (results presented in Figure 1). The results of this preliminary selection led to the return of approximately 1800 unique works (from all the databases). A preliminary validation was manually performed (by reading the keywords and abstract) in order to remove the "false-positive" results. The final validation was performed by reading the entire manuscript. The criteria for inclusion in the present review were: (i) the use of phytosynthesized nanoparticles that were obtained in the laboratory; (ii) the existence of analytical studies for the characterization of the nanoparticles; and (iii) in-depth applications reports. The review is structured in different chapters for each potential application that is related to the toxic effect of the metallic nanoparticles.

“…Green synthesis of metallic nanomaterials are of great interests owing to their sustainable production and being free from environmentally toxic chemicals [1]. Utilization of plant extracts [2][3][4][5], simple sugars [6], microorganisms [7] and carbohydrate polymers [6] are among the greener approaches. Among these approaches, the use of plant extracts are the most widely preferred route in the synthesis of metallic nanostructures including gold [6], silver [8], copper [9] and platinum [10].…”

There is an increasing demand in the synthesis of shape and size-controlled gold nanostructures (Au NSs) with greener methods. Therefore, we aimed to synthesize differently shaped and sized Au NSs using a greener technique under ambient conditions. In this study, we utilized pollen extracts of Corylus avellana, Juniperus oxycedrus and Pinus nigra species (collected from Kastamonu region of Turkey) for the synthesis. The extraction was performed in water in order to recover "water soluble" content from the pollen grains. The extracts were used to stabilize, and direct shape and size of the HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) buffer synthesized Au NSs. UV-vis, powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) characterizations proved synthesis of spherical, anisotropic and large Au NSs with this benign approach. The obtained Au NSs were possible to separate small and large Au NSs through centrifugation. Chemistry of pollen extracts played a key role on the morphology and stability of the Au NSs. The findings, for the first time, is revealing the synthesis of large Au nanorod bundles (>300 nm) along with hexagonal and spherical Au NSs under ambient conditions using pollen grain extracts, whose maturation took 24h.

“…Generally, the eco-toxicity investigative studies have been conducted on model organisms (such as bacteria, fungi, algae, small crustaceans, worms, shrimp, rats and fish) when exposed to AgNPs in a uniform experimental medium setup (such as sediment, solid media and water) for limited duration (1day to 8-weeks) [169,174,177,182]. Hence, it is possible to determine the toxic effects and mechanisms involved in the toxicity of AgNPs in regard to specific organism or species.…”

In recent years, fabrication of AgNPs via plant extracts has gained much attention because of being environmentally friendly, non-hazardous and cost effective. The bio-fabrication of AgNPs using plant extracts as reducing, capping and stabilizing agents includes simpler, safer, less-toxic and energy efficient. AgNPs have been widely applied in numerous fields due to their bio-compatibility, multifunctionality, solubility, high stability, therapeutic and adhesive properties. This review focuses on the advantages of AgNPs synthesis using plant extracts and its applications in various fields for the betterment of mankind and environment with numerous examples and also highlights on explaining possible fundamental mechanisms involved in antimicrobial and anticancer activities of plant extract synthesized AgNPs.
