“…It is also reported that an increase in the temperature increased the intensity level of the plasmonic band and decreased the nano-silver diameter ( Dada et al, 2018 ). Temperature-dependent increase in aggregation of larger particles and nano-silver grain modification agrees with the previously published work ( Shahjahan et al, 2017 , Munir et al, 2021 ). Besides, the 3000.01 (OH) and (CH 2 ) 2053.61 cm −1 are responsible for reducing AgNO 3 to Ag-NPs The given functional groups are attached on the surface of nano-silver as reported by ( Muzamil et al, 2014 , Hamedi et al, 2017 , Elumalai et al, 2017 ).…”

“…Diffracted peaks were calculated at (1 1 1) and (2 0 0); miller indices of these peaks compared with standard card JCPDS number 4–0783 ( Lanje et al, 2010 ). The octahedral crystal structure and crystallite size of pure nano-silver were increased by increasing the temperature and is consistent with the previous work ( Singh et al, 2010 , Allafchian et al, 2016 , Munir et al, 2021 ). It is also reported that an increase in the temperature increased the intensity level of the plasmonic band and decreased the nano-silver diameter ( Dada et al, 2018 ).…”

“…The AgNPs displayed minimal agglomeration in water with an increased effective diameter in media, due to the formation of a protein corona [ 38 ]. As the NPs had a PVP surface coating, which is known to promote particle stability in solution, the small extent of aggregation was expected [ 39 ]. Additionally, the surface charge was assessed using zeta potential measurements.…”

Characterizing the Role of Biologically Relevant Fluid Dynamics on Silver Nanoparticle Dependent Oxidative Stress in Adherent and Suspension In Vitro Models

Silver nanoparticles (AgNPs) are being employed in numerous consumer goods and applications; however, they are renowned for inducing negative cellular consequences including toxicity, oxidative stress, and an inflammatory response. Nanotoxicological outcomes are dependent on numerous factors, including physicochemical, biological, and environmental influences. Currently, NP safety evaluations are carried out in both cell-based in vitro and animal in vivo models, with poor correlation between these mechanisms. These discrepancies highlight the need for enhanced exposure environments, which retain the advantages of in vitro models but incorporate critical in vivo influences, such as fluid dynamics. This study characterized the effects of dynamic flow on AgNP behavior, cellular interactions, and oxidative stress within both adherent alveolar (A549) and suspension monocyte (U937) models. This study determined that the presence of physiologically relevant flow resulted in substantial modifications to AgNP cellular interactions and subsequent oxidative stress, as assessed via reactive oxygen species (ROS), glutathione levels, p53, NFκB, and secretion of pro-inflammatory cytokines. Within the adherent model, dynamic flow reduced AgNP deposition and oxidative stress markers by roughly 20%. However, due to increased frequency of contact, the suspension U937 cells were associated with higher NP interactions and intracellular stress under fluid flow exposure conditions. For example, the increased AgNP association resulted in a 50% increase in intracellular ROS and p53 levels. This work highlights the potential of modified in vitro systems to improve analysis of AgNP dosimetry and safety evaluations, including oxidative stress assessments.

“…The use of silver for the development of nanoparticles increased initially because of its biomedical applications, mainly as an effective antimicrobial agent [3,19]. Over the years, with the improvement of studies in relation to nanomaterials, it was possible to recognize several possibilities of application for silver nanoparticles (Ag-NPs), such in the development of food packaging to protect against microorganisms [20,21], the production of biosensors [22,23], and water decontamination [24,25].…”

Biosynthesis of Silver Nanoparticles Mediated by Entomopathogenic Fungi: Antimicrobial Resistance, Nanopesticides, and Toxicity

et al. 2021

View full text Add to dashboard Cite

Silver nanoparticles are widely used in the biomedical and agri-food fields due to their versatility. The use of biological methods for the synthesis of silver nanoparticles has increased considerably due to their feasibility and high biocompatibility. In general, microorganisms have been widely explored for the production of silver nanoparticles for several applications. The objective of this work was to evaluate the use of entomopathogenic fungi for the biological synthesis of silver nanoparticles, in comparison to the use of other filamentous fungi, and the possibility of using these nanoparticles as antimicrobial agents and for the control of insect pests. In addition, the in vitro methods commonly used to assess the toxicity of these materials are discussed. Several species of filamentous fungi are known to have the ability to form silver nanoparticles, but few studies have been conducted on the potential of entomopathogenic fungi to produce these materials. The investigation of the toxicity of silver nanoparticles is usually carried out in vitro through cytotoxicity/genotoxicity analyses, using well-established methodologies, such as MTT and comet assays, respectively. The use of silver nanoparticles obtained through entomopathogenic fungi against insects is mainly focused on mosquitoes that transmit diseases to humans, with satisfactory results regarding mortality estimates. Entomopathogenic fungi can be employed in the synthesis of silver nanoparticles for potential use in insect control, but there is a need to expand studies on toxicity so to enable their use also in insect control in agriculture.
