“…19 Recently, Ag nanoparticles were prepared by using agar solutions as the reducing agents and/or surfactants. 20,21 However, these preparation approaches required higher temperature or strong light illumination to prompt the reduction of Ag + in aqueous agar solution. Herein, we report on the synthesis of a concave-cubic AgCl@Ag photocatalyst through a facile, mild and eco-friendly route by using agar gel as a mediated agent.…”

A facile biomaterial-assisted method has been developed to fabricate AgCl@Ag concave cubes. The biomaterial agar gel was used to moderate the reaction process by providing a reaction matrix to mediate the diffusion of reactants and confine the growth of AgCl@Ag concave cubes. The whole reaction process was performed under mild conditions without heat treatment or organic additives. The as-formed AgCl@Ag concave cubes as a photocatalyst exhibit effective activity for photocatalytic degradation of methyl orange (MO) under visible-light irradiation, which is mainly attributed to the surface plasmon resonance (SPR) of Ag nanoparticles.

“…[16][17][18][19][20] PDT efficacy in the presence of combined ALA and silver nanoparticles (ALAAgNPs) was demonstrated, resulting in higher efficiency than ALA alone. 20,21 AgNPs can be synthesized by several physical, chemical, and biological methods, and engineered nanomaterials [22][23][24][25][26][27] have various biomedical, food processing, and agrochemical applications when conjugated with a ligand. Silver nanoparticles (AgNPs) are an effective pest management agent in agriculture, on account of known surface plasmon resonance (SPR) characteristics, and are a potential tool to act as nanopesticides.…”

“…The possibility of incorporating nanoparticles into fabrics, polymers, paints, electronics, diagnostic methods, etc requires specific parameters of the nanoparticles such as size, shape, dispersion, and solubility in various solvents. Nanoparticle synthesis may be performed using various methods including polysaccharide reduction, irradiation (microwave, 7 ultraviolet, 8 laser, 9 gamma radiation, 10 artificial sunlight 11 ), the Tollens method, and biological synthesis (using extracts from plants, bacteria, fungi, as well as peptides and live organisms). 12 These approaches allow to obtain the desired product, however, they may considerably benefit from several alterations.…”

A fast, economical, and reproducible method for nanoparticle synthesis has been developed in our laboratory. The reaction is performed in an aqueous environment and utilizes light emitted by commercially available 1 W light-emitting diodes (λ =420 nm) as the catalyst. This method does not require nanoparticle seeds or toxic chemicals. The irradiation process is carried out for a period of up to 10 minutes, significantly reducing the time required for synthesis as well as environmental impact. By modulating various reaction parameters silver nanoparticles were obtained, which were predominantly either spherical or cubic. The produced nanoparticles demonstrated strong antimicrobial activity toward the examined bacterial strains. Additionally, testing the effect of silver nanoparticles on the human keratinocyte cell line and human peripheral blood mononuclear cells revealed that their cytotoxicity may be limited by modulating the employed concentrations of nanoparticles.
