“…The adsorbed surfactant molecules from the solution prevent the coalescence of particles and control the rate of particle exaggeration. By choosing the proper kind or concentration of the surface active agent, the size of particles composed in the solution can be contained on a nanometer scale [111][112][113][114][115][116][117]. A process patent has been granted to Li and Ong [118] for the preparation of silver nanoparticles and the formation of molecules of an initial stabilizer on the surface of the nanoparticles, as well as the mixing of a replacement stabilizer composed mainly of a carboxylic acid also with composition to substitute at least a portion of the primary stabilizer with the replacement stabilizer, resulting in molecules of the initial stabilizer on the surface of the nanoparticles [119][120][121][122][123][124][125][126][127][128][129][130].…”

Silver nanoparticles in the range from 1 to 100 nm are widely used in industrial applications as catalysis, electronics, and photonics, and they have unique properties such as optical, electrical, and magnetic characteristics that can be used as antimicrobial, biosensor textile, cosmetics, composite fibers, and electronic components and to amend shelf life of food substances. The main objective of the present review was to focus on formulation methods of silver nanoparticles with recent advances and future aspects. Silver nanoparticle shows very high potential towards biological applications. Several physicals, chemical, and various biological techniques have been employed to synthesize and stabilize silver nanoparticles. For the manufacture of silver nanoparticles, multiple methods, including chemical simplification with different natural and inorganic decreasing agents, physicochemical reduction, electrochemical procedures, and radiolysis, are employed. Silver nanoparticles are the single most manufacturer-identified material that can be used in all nanotechnology products. They can be used in food packing polymers to enhance the shelf lifespan. The present review is aimed at different types of synthesis and details of silver nanoparticles used as drug delivery vehicles, antibacterial activity, toxicity, recent advances, and future aspects.

“…Catapol and its precursor aucubin are the most common iridoid glycosides in P. lanceolata 36 . Plantago lanceolata is widely used to treat blisters, stomach disorders, uterine cancer, pimples, homeostatic, TB, asthma, bronchitis, and diarrhea 37 – 40 . The secondary metabolites present in the leaves, roots, and bark are responsible for therapeutic potential.…”

Silver nanoparticles (Ag. NPs) have shown a biological activity range, synthesized under different environment-friendly approaches. Ag. NPs were synthesized using aqueous crude extract (ACE) isolated from Plantago lanceolata. The ACE and Ag. NPs were characterized and assessed their biological and antioxidant activities. The existence of nanoparticles (NPs) was confirmed by color shift, atomic force microscopy (AFM), and UV–Vis’s spectroscopy. The FT-IR analysis indicated the association of biomolecules (phenolic acid and flavonoids) to reduce silver (Ag+) ions. The SEM study demonstrated a sphere-shaped and mean size in the range of 30 ± 4 nm. The EDX spectrum revealed that the Ag. NPs were composed of 54.87% Ag with 20 nm size as identified by SEM and TEM. AFM has ended up being exceptionally useful in deciding morphological elements and the distance across of Ag. NPs in the scope of 23–30 nm. The TEM image showed aggregations of NPs and physical interaction. Ag. NPs formation also confirmed by XPS, DRS and BET studies. Ag. NPs showed efficient activity as compared to ACE, and finally, the bacterial growth was impaired by biogenic NPs. The lethal dose (LD50) of Ag. NPs against Agrobacterium tumefaciens, Proteus vulgaris, Staphylococcus aureus, and Escherichia coli were 45.66%, 139.71%, 332.87%, and 45.54%, with IC50 (08.02 ± 0.68), (55.78 ± 1.01), (12.34 ± 1.35) and (11.68 ± 1.42) respectively, suppressing the growth as compared to ACE. The antioxidant capacity, i.e., 2,2-diphenyl-1-picrylhydrazyl (DPPH) of Ag. NPs were assayed. ACE and Ag. NPs achieved a peak antioxidant capacity of 62.43 ± 2.4 and 16.85 ± 0.4 μg mL−1, compared to standard (69.60 ± 1.1 at 100 μg mL−1) with IC50 (369.5 ± 13.42 and 159.5 ± 10.52 respectively). Finally, the Ag. NPs synthesized by P. lanceolata extract have an excellent source of bioactive natural products (NP). Outstanding antioxidant, antibacterial activities have been shown by NPs and can be used in various biological techniques in future research.

“…Currently, many researchers have inclined their interests toward the secondary metabolites from various parts of plants as a route of synthesis of metal/metal oxide nanoparticles [ 179 ]. Green metal/metal oxide nanoparticles are highly used in various applications such as antibacterial, antioxidant, anti-inflammatory, catalytic, and cytotoxic activities [ 180 ]. Even though few studies have been carried out on the green synthesis using aquatic and semiaquatic plant extracts, some earlier studies revealed that these plants are rich sources of stronger bioreductants for synthesizing metallic nanoparticles.…”

Medicinal plants have been treating various ailments and diseases since ancient times. Aquatic and semiaquatic medicinal plants play an essential role in human welfare to fulfill their daily needs. They have shown biological, pharmacological, nutraceutical, and commercial applications. This review aims to collect and update all recent information on ethnomedicinal, phytochemistry, pharmacological activities, and nanoparticle synthesis and their uses in aquatic and semiaquatic medicinal plants. Original research papers, review papers, short communications, and book chapters on aquatic and semiaquatic plants have been retrieved from PubMed, Web of Science, Scopus, and Google Scholar. Keywords, ethnomedicinal studies, phytochemistry, pharmacological activities, and nanoparticle synthesis from aquatic and semiaquatic medicinal plants are used for the search. Different aquatic and semiaquatic medicinal plants belonging to the families Acanthaceae, Alismataceae, Amaranthaceae, Apiaceae, Araceae, Asteraceae, Boraginaceae, Ceratophyllaceae, Cyperaceae, Fabaceae, Hydrocharitaceae, Lythraceae, Marsileaceae, Menyanthaceae, Nelumbonaceae, Nymphaeaceae, Onagraceae, Plantaginaceae, Poaceae, Polygonaceae, Pontederiaceae, Primulaceae, Scrophulariaceae, and Zingiberaceae have been studied. They are rich in alkaloids, flavonoids, terpenoids, phenolics, saponins, tannins, dietary fiber, glycosidic derivatives, carbohydrates, and proteins. These phytochemicals have been used for their antimicrobial, antioxidant, hepatoprotective, sedative, anticonvulsant, cytotoxic, antiparasitic, and antidiabetic activities. Besides this, various parts of the plants are used as dietary supplements and green nanoparticle synthesis. These plants are also known for their commercial value and are used as an ingredient in some pharmaceutical industries.
