Preparation and properties of silver nanoparticles loaded in activated carbon for biological and environmental applications

Antiadherence and Antimicrobial Properties of Silver Nanoparticles against Streptococcus mutans on Brackets and Wires Used for Orthodontic Treatments

“…Various studies have shown that a coverage of AgNPs in Journal of Nanomaterials human dentin can prevent biofilm formation on the surface of the dentin as well as inhibit bacterial growth around it [18,24]. According to the characterization of AgNPs, it is very well known that particles with zeta potential values between +30 and −30 mV are considered a stable suspension limiting the agglomeration [25,26]. It has been reported that the concentration of AgNO 3 (0.01, 0.1, and 0.5 M) can affect the size of silver nanoparticles (20,25, and 11 nm) and the zeta potential values (−26.37, −37.95, and −28.23, resp.…”

Synthesis of Silver-Graphene Oxide nanocomposite for removal of anionic dye by adsorption

“…Since eosin yellow does not contain any OH and NH 2 group, n-π EDA interaction is not possible between them [38].The high surface area of graphene oxide acts as the ideal support for the dispersion of high surface area of silver nanoparticle. The adsorption capacity of AgGO nanocomposite was greater than GO nanosheets because of the high surface area of silver nanoparticle at nanometer level [39][40][41]. Silver nanoparticle binds more strongly with dyes than any other nanoparticle and hence increases the adsorption capacity of AgGO than GO.…”

Synthesis and characterization of metallic nanoparticles impregnated onto activated carbon using leaf extract of Mukia maderasapatna: Evaluation of antimicrobial activities

“…Consequently, the interest in the embedding of metallic nanoparticles on the activated carbon has been developed and successfully used in antimicrobial studies. Recently, the activated carbon from natural sources has been explored as an effective adsorbent in the treatment of microorganisms [3,27,29,30]. As the activated carbon has a stronger affinity for adsorbing the organic substances at lower concentrations due to its large specific surface area and porous nature.…”
