“… Kudzu ligands, such as daidzein and puerarin possess potent anti-inflammatory and anti-oxidation properties, thus protecting against alcohol-mediated disorders [ 28 , 29 , 94 , 95 , 96 , 97 ]. As shown in Figure 10 , ethanol induces oxidative stress and ensuing downstream activation of p50–p65 (a pro-inflammatory dimer of NFκB) and suppression of p50–p50 (an anti-inflammatory dimer of NFκB), resulting in dysregulation of inflammation and activation of pro-apoptosis signaling [ 32 ]. The addictive effects of ethanol are mediated by the brain addiction pathways including dopamine, GABA, NMDA, and serotonin neurons [ 5 , 98 , 99 ].…”

“…Plant Extract Synthesized Nanoparticles: Earlier studies have described “green” synthesis of gold and silver NPs using plant extracts that are environment friendly, cost effective, easily scaled up for large scale syntheses of nanoparticles, and do not require stabilizers such as polyethylene glycols [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Most importantly, the “green” nanoparticles may retain the therapeutic potency of the plant and the unique properties of NPs.…”

The present study describes potential beneficial and adverse effects of plant-extract synthesized gold nanoparticles (AuNPs) on ethanol toxicity in SH-SY5Y cells. Although kudzu root extract (K), edible-gum extract (G), alone or in combination (KG), reduced Au3+ into AuNPs, the extract’s composition and the reaction temperature determined their size (AuNPKG(90<50<37) << AuNPK (90,50<37) < AuNPG (90<50); the subscript KG, K, or G is extract identification and numerical vales are reaction temperature in Celsius) and biological properties (AuNPKG (90,50>37) << AuNPK (90,50>37) < AuNPG (90,50)). The surface of each AuNP contained the extract’s active ingredients, that were analyzed and confirmed using laser desorption ionization (LDI)) and low-matrix laser desorption-ionization (LMALDI). AuNPKG-50 was (i) least toxic to SH-SY5Y cells, but most effective in suppressing the adverse effects of ethanol on SH-SY5Y cells, and (ii) more effective than a combination of free kudzu and gum extracts. The beneficial and adverse effects of AuNPs may have been modified by the formation of proteins corona. This study provides a proof of concept for possible application of plant-extract synthesized AuNPs in mitigating ethanol toxicity.

“…Photocatalytic activity of AgNPs biosynthesized from the extract of lychee (L. chinensis) was reported to be significantly higher when compared to commercial AgNPs; 99.24% of methylene blue degraded within 11 min. e catalytic activity was maintained even after the third time of reusing the AgNPs [38]. e high activity is attributed by the small size of AgNPs that provides large surface area for catalysis to occur on the surface of nanoparticles [38].…”

Biosynthesized or biogenic metallic nanoparticles, particularly silver and gold nanoparticles (AgNPs and AuNPs, respectively), have been increasingly used because of their advantages, including high stability and loading capacity; moreover, these nanoparticles are synthesized using a green and cost-effective method. Previous studies have investigated reducing and/or stabilizing agents from various biological sources, including plants, microorganisms, and marine-derived products, using either a one-pot or a multistep process at different conditions. In addition, extensive studies have been performed to determine the biological or pharmacological effects of these nanoparticles, such as antimicrobial, antitumor, anti-inflammatory, and antioxidant effects. In the recent years, chitosan, a natural cationic polysaccharide, has been increasingly investigated as a reducing and/or stabilizing agent in the synthesis of biogenic metallic nanoparticles with potential applications in nanomedicine. Here, we have reviewed the mechanism of biosynthesis and potential applications of AgNPs and AuNPs and their chitosan-mediated nanocomposites in nanomedicine.

Nowadays production of different nanoparticles (NPs) with plausible biomedical benefits is tremendously increasing. NPs are of great interest in drug delivery systems, drug formulation, medical diagnostic, and biosensor production. Aside from the importance of NPs in medicine, their negative side effects including potential cytotoxicity, inflammatory response induction, and drug interruption should be carefully considered. Several molecular and physicochemical mechanisms are involved in toxicity induction of NPs. Finding the negative effects of NPs on human tissues and investigation of their mechanism of action are a way for preventing the happening of unpleasant event. Here in this work, we would describe the main way of NP production with special attention to green NP production, and then their application in medical diagnosis and disease treatment would be explored. Also the main toxicity effects of NPs on different tissues would be explored, and the parameters affecting the quality of NPs and their corresponding biological properties would be highlighted.
