“…Nanoparticle agglomerates were reported to be less likely internalized into cells and/or tissues, but may be adsorbed to cell membranes [59]. Other metal-based NPs (e.g., lead (nPb)) were adsorbed on S. minima cell walls in roots and fronds irrespective of their morphology (spherical or elongated) [60]. Numerous studies have reported accumulation of NPs in aquatic higher plants through either internalization-or adsorption-driven processes as summarized in Table 1.…”

“…Generally, smaller-sized NPs are more rapidly internalized by aquatic higher plants [61]. However, data reveals that accumulation is dependent on complex and multifactorial factors, broadly categorized as physicochemical properties of NPs (e.g., size [20], coating type [62], morphology [60]), NPs type [63], exposure concentration [51,64], and plant physiological and phenotypic characteristics, e.g., presence of root hairs [20,65] (Table 1). Thus, in light of SEM and ICP-MS results (Figures 4 and 5, respectively), adsorption mechanism accounted for the observed accumulation of nAu in S. minima.…”

Interactions of Coated-Gold Engineered Nanoparticles with Aquatic Higher Plant Salvinia minima Baker

The study investigated the interactions of coated-gold engineered nanoparticles (nAu) with the aquatic higher plant Salvinia minima Baker in 2,7, and 14 d. Herein, the nAu concentration of 1000 µg/L was used; as in lower concentrations, analytical limitations persisted but >1000 µg/L were deemed too high and unlikely to be present in the environment. Exposure of S. minima to 1000 µg/L of citrate (cit)- and branched polyethyleneimine (BPEI)-coated nAu (5, 20, and 40 nm) in 10% Hoagland’s medium (10 HM) had marginal effect on biomass and growth rate irrespective of nAu size, coating type, or exposure duration. Further, results demonstrated that nAu were adsorbed on the plants’ roots irrespective of their size or coating variant; however, no evidence of internalization was apparent, and this was attributed to high agglomeration of nAu in 10 HM. Hence, adsorption was concluded as the basic mechanism of nAu accumulation by S. minima. Overall, the long-term exposure of S. minima to nAu did not inhibit plant biomass and growth rate but agglomerates on plant roots may block cell wall pores, and, in turn, alter uptake of essential macronutrients in plants, thus potentially affecting the overall ecological function.

“…It was concluded that the presence of several phytochemicals like carbohydrates, phenols, flavonoids, and terpenoids might have played a major role in the bioreduction process. Castro-Longoria et al (2014) successfully developed an eco-friendly method for the synthesis of lead nanoparticles from Salvinia minima (family: Salviniaceae), a free floating fern. This non-rooted aquatic fern grows wild in South America and Mesoamerica and is referred to as "common Salvinia."…”

Green Nanoparticles: The Future of Nanobiotechnology

Pteridophytes, also known as "vascular cryptogams," were the first vascular plants that evolved a system of vascular elements. Ferns and lycophytes, believed to be among the oldest lineages of terrestrial plants, are thought to have evolved around 400 million years ago, possibly in the Ordovician or Silurian period when a major divergence event led to separation of bryophytes from the ancestral tracheophytes. The use of pteridophytes for biological production is meager and has been restricted to studies in a few genera. Mostly, fabrication of metal nanoparticles has been carried out using plants of this group which have numerous medicinal properties. However, scant studies available point toward great scope in their utilization in future research programs involving green synthesis of a wide range of nanoparticles.
