Adsorption preconcentration of pyrene by silver nanoparticles and its determination in aqueous solutions

Gold and silver nanoparticles‐based laser desorption/ionization mass spectrometry method for detection and quantification of carboxylic acids

“…For example, Hidalgo et al used discussed properties presenting effective nonsteroidal anti-inflammatory drugs extraction method with AgNP-containing agar film 27. Vasil'eva et al presented the possibility of using silver nanoparticles to preconcentrate pyrene, which is an aromatic compound of very low polarity 28. Sherrod et al studies showed selective binding of AgNPs with olefins, a carbon-carbon double bond-containing group very close in structure with unsaturated fatty acids studied in this work 29.…”

“…In case of 109 AgNPs, mainly silver-109 adducts are formed, whereas for AuNPs, sodium, potassium, and proton adducts were found. It is known from literature that AgNPs form strong interactions with low-polarity compounds and can be used to concentrate various compounds such as low-polar drugs, polyaromatic hydrocarbons, or olefinic compounds [26][27][28][29]. For example, Hidalgo et al used discussed properties presenting effective nonsteroidal anti-inflammatory drugs extraction method with AgNP-containing agar film 27.…”

Silver nanoparticles for separation and preconcentration processes

“…Olenin et al [33,34] used adsorption-luminescence methods to combine the preconcentration of polyaromatic hydrocarbons (PAHs), such as pyrene, on the adsorbent surface and their subsequent luminescence determination directly in the adsorbent matrix. For this purpose they used hydrophobic AgNPs with an average size of 4 nm, which were synthesized in two-phase water-organic emulsions.…”

The formation of mono- and bimetallic silver-containing seed nanoparticles

“…Silver nanoparticles with different sizes (from 1 to 100 nm) and geometry parameters possess a unique combination of valuable properties due to surface plasmon resonance (SPR), highly developed surface area, and catalytic activity [1][2][3][4][5][6][7]; their dispersions are characterized by long term aggregation stability owing to high absolute values of the ζ potential of particles.…”
