Hyaluronan-assisted synthesis of silver nanoparticles and nanowires

Silver Nanowire Synthesis and Applications in Composites: Progress and Prospects

“…[98,99] AgNWs have also been fabricated in aqueous reaction systems involving inorganic ions (NaOH and NaCl) or organic substances (CTAB, trisodium citrate (TSC), sodium dodecyl sulfate (SDS), cholesteryl pyridine carbamate (CPC), 5-hydroxytryptophan (5-HTP), and sodium dodecylsulfonate (SDSN)) as stabilizers or attractants, which are referred to as wet chemical methods. [70,[100][101][102][103][104][105][106] The typical mechanism of AgNW synthesis via a wet-chemical process (using CPC as a soft template) is shown in Figure 3c. Specifically, a chiral gelator (CPC) forms a gel comprising long nanotubes in a mixture of water and anisole.…”

Brief review on recent outcomes of applications of green synthesis vs chemical synthesis of silver nanoparticles

“…42,43 But later, this methodology is found to be highly hazardous and costly due to usage of toxic chemical stabilisers, reducers, capping agents and solvents over the green approach of silver nanoparticles preparation by the scientific community when considered for clinical, biomedical, therapeutics, diagnostic, pharmaceutical and cosmetic applications. [43][44][45] Chemical reduction is the most common chemical method of silver nanoparticle synthesis in which reduction of metal salts is carried out by organic and inorganic reducing agents like sodium citrate, ascorbate, N, N-dimethylformamide, toluene and sodium polyacrylate are used to reduce Ag + to Ag 0 to prevent agglomeration and stabilization. [44][45][46] Among other reported chemical methods, microemulsion techniques were also involved for silver nanoparticles preparation by using two immiscible organic phases for separation of metal saltreducer complex which stabilised by alkyl groups which required huge amount of chemicals.…”

Fast synthesis of silver nanowires at room temperature via ultrasonication-mediated galvanic replacement for flexible transparent electrodes

“…[9][10][11][12][13][14][15] The properties of AgNWs, which lead to their diverse application performance with high optical transparency and low sheet resistance, are significantly determined by their preparation method. 16 Recently, many preparation methods have been reported, including the polyol method, [17][18][19] template method, 20,21 wet chemical method, 22,23 photo-reduction method, 24 and seedmediated method. 25 Previous studies demonstrated that the polyol method is the most promising strategy, but it usually requires high-temperature and high-pressure conditions and its final products need to go through complicated purification, 26 which undoubtedly increases the cost of preparation.…”
