Silver Nanoparticles

Impacts of metal-based engineered nanomaterials on soil communities

“…If this takes place in the presence of MENM is not clear, as to date our knowledge on effects of MENM on soil fungi and Ar-chaea is very limited. 43,54 The generally higher metal susceptibility of bacteria due to their prokaryotic nature 49 is supported by a study with mineral silver compounds including metal-accumulating fungi. 55 On the other hand, MENM are also highly efficient fungicides.…”

“…44 AgNP are more effective against Gram-negative bacteria than Gram-positive: e.g., various types of fungal-produced AgNP (5-56 nm) completely inhibited Pseudomonas putida at 0.8 mg L −1 . 49,50 Pawlett et al 51 report bactericidal effects of nZVI on Gram-positive bacteria in soils. Premanathan et al 52 showed higher sensitivity of Grampositive bacteria towards ZnONP.…”

“…A stimulation of EPS production by bacteria has also been shown for AgNP, ZnONP and Cu-doped TiO 2 NP. 16 In their review on AgNP and microorganisms, Sweet and Singleton 49 recommend that future studies focus on "biofilm communities as a more pertinent system when regarding food, medical and environmental systems" (see also ref. 120).…”

Nanotechnology-Applied Curcumin for Different Diseases Therapy

“…Silver has usually been utilized as an incredibly efficient material for antimicrobial utility [138]. In small concentrations, it is safe for human cells but lethal for the majority of bacteria and viruses [139].…”

“…In small concentrations, it is safe for human cells but lethal for the majority of bacteria and viruses [139]. With development of nanotechnology, it has become the metal of choice in restricting microbial growth and expansion in a variety of nanoparticle-related requests [138]. Silver nanoparticles are identified for their brilliant optoelectronic properties originated from surface plasmon resonance.…”
