One-step synthesis of lignosulfonate-stabilized silver nanoparticles

Synthesis and characterization of Acacia lignin-gelatin film for its possible application in food packaging

“…AFM is an excellent and advanced tool for topography analysis of materials (Milczarek et al 2013). AFM surface topography mapping of 10 × 10 µm to 625 × 625 nm areas on the surface of the lignin-gelatin film show that the film surface is smooth without clumping or aggregates of lignin and gelatin molecules; however, at the lower scanning areas of 1.25 × 1.25 µm some roughness was observed (Fig.…”

Hydrogen peroxide sensing and cytotoxicity activity of Acacia lignin stabilized silver nanoparticles

“…However, the literature reports limited synthesis of silver nanoparticles using agriculture or forest wastes such as banana, Annona squamosa and mango peel extract [6,14,15].The property to act as both stabilizing and reducing agent marks the advantage of using biological compounds over organic chemicals for the synthesis of nanoparticle. Traditionally, for the synthesis of silver nanoparticles, several reducing agents like Page 4 of 34 A c c e p t e d M a n u s c r i p t sodium borohydride (NaBH 4 ), formaldehyde, sodium citrate, hydrazine, ascorbic acid, glucose and UV irradiation are utilized to reduce the silver cations [16,17].Some polymeric materials such as poly(vinyl pyrrolidone), poly(ethylene glycol), and surfactants are also used as stabilizers to prevent nanoparticles agglomeration and precipitation [18,19].…”

“…Literature shows that the polyphenols like poly-eugenol and kraft lignin serve as an effective stabilizing agent for gold nanoparticles and dispersing agent for carbon nanotubes, respectively. Acacialignins are potent antioxidant and could be possibly used to reduce metal ions that display a relatively high redox potential [16,21].…”

Bakteriobójcza aktywność koloidów srebra stabilizowanych hydrolizatami skrobiowymi oraz ich wpływ na wytrzymałość zapraw cementowych

“…W pewnych sytuacjach jeden związek może służyć zarówno jako reduktor, jak i środek stabilizujący, np. lignosulfoniany, polisacharydy (Milczarek, Rebis i Fabianska, 2013;Konował, Modrzejewska--Sikorska i Milczarek, 2015).…”
