“…Fructose, the monosaccharide used in this study, is a nontoxic reducing agent and constitutes a cheap and abundant natural source for the synthesis of inorganic NPs, such as AuNPs [37]. This reducing character is achieved in its open-chain form and maximized with its ionization [37]. In combination, reducing sugars and stabilizing biopolymers can mediate the formation of stable, morphologically controlled NPs.…”

Silver selenide (Ag2Se) is a promising nanomaterial due to its outstanding optoelectronic properties and countless bio-applications. To the best of our knowledge, we report, for the first time, a simple and easy method for the ultrasound-assisted synthesis of Ag2Se nanoparticles (NPs) by mixing aqueous solutions of silver nitrate (AgNO3) and selenous acid (H2SeO3) that act as Ag and Se sources, respectively, in the presence of dissolved fructose and starch that act as reducing and stabilizing agents, respectively. The concentrations of mono- and polysaccharides were screened to determine their effect on the size, shape and colloidal stability of the as-synthesized Ag2Se NPs which, in turn, impact the optical properties of these NPs. The morphology of the as-synthesized Ag2Se NPs was characterized by transmission electron microscopy (TEM) and both α- and β-phases of Ag2Se were determined by X-ray diffraction (XRD). The optical properties of Ag2Se were studied using UV–Vis spectroscopy and its elemental composition was determined non-destructively using scanning electron microscopy–energy-dispersive spectroscopy (SEM–EDS). The biological activity of the Ag2Se NPs was assessed using cytotoxic and bactericidal approaches. Our findings pave the way to the cost-effective, fast and scalable production of valuable Ag2Se NPs that may be utilized in numerous fields.

“…Amino acids as well as sugars are reported to reduce the gold salts into GNP. [23][24][25][26][27][28] Glycolipids are also reported to reduce the metals to form nanoparticles. [29][30][31][32] The presence of these moieties in the gelator structure motivated us to use this synthetic glycolipid amphiphile for in situ reduction of gold within the gel.…”

“…18 After this report, researchers have tried such in situ reduction of gold within supramolecular gels using different types of gelators such as ascorbic acid based amphiphiles, 19 fatty N -acylamino hydrazides, 20 N -acyl glutamine derivatives, 21 tryptophan-containing peptide amphiphiles, 22 tyrosine containing oligopeptide, 23 and amino acid based gelators. 24 Along with amino acid derivatives, many sugars such as agarose, 25 fructose, 26 chitosan, 27 and amino-dextran 28 have been reported as reducing as well as capping agents in GNP synthesis. Research in this area has recently started thriving to develop modernized LMWG for designing efficient nanocomposite gels.…”
