“…This binding diminishes the membrane permeability and leads to cell death [ 39 ]. Specifically, MIC value against gram-positive E. faecalis bacteria has been found in an interval between 500 and 0.19 μg/mL, depending on synthesis route, particle size, and surface modification [ 39 , 40 , 41 , 42 ]. Accordingly, the Ag-O coordination bonds among AgNPs and COO − moieties of CMC do not blur the ability of nanoparticles to produce and release Ag + from their surface, thus, to display a remarkable antibacterial activity in aqueous media.…”

In this paper we report on the influence of polysaccharides’ molecular structure on the antibacterial activity and cytotoxicity of composites based on silver nanoparticles (AgNPs) immobilized into carboxymethyl-cellulose (CMC). These composites were green synthesized from the reduction of silver ions into aqueous solutions of the polysaccharide, using CMC with different degree of substitution (DS) and molecular weight (Mw). The composites were characterized by transmission electron microscopy (TEM), as well as infrared (ATR-FTIR), ultraviolet (UV-Vis), Raman, and X-ray photo-electron (XPS) spectroscopic techniques. The antibacterial activity was evaluated with minimum inhibitory concentration against Enterococcus faecalis. The cytotoxicity of composites was assessed against human gingival fibroblast. Experimental evidence suggests that particle size distribution and morphology of AgNPs change according to the quantity of silver precursor added to the reaction, as well as the DS and Mw of CMC used for composites preparation. This is related to the dispersion of silver precursor into aqueous solutions of the polysaccharide and the formation of Ag-O coordination bonds among AgNPs and COO− moieties of CMC. Moreover, these coordination bonds modify the ability of nanoparticles to produce and release Ag+ into aqueous dispersion, adjusting their antibacterial activity and the induction of cytotoxicity into the tested biological environments.

“…The present phytochemicals (flavonoids) and silver ions could serve as antioxidants through single electron and hydrogen atom transfer [127]. Other theory was presented by Vijayan et al [128], who indicate that the increased antioxidant properties of nanoparticles compared to extract can be attributed to the adsorption of bioactive compounds of leaf extract over spherically shaped nanoparticles. Analogically, AgNPs prepared by extract of Melia azedarach exhibited higher antioxidant capacity according to extract [129].…”

Our objective in this review article is to find out relevant information about methods of determination of antioxidant activity of silver nanoparticles. There are many studies dealing with mentioned problem and herein we summarize the knowledge about methods evaluating the antioxidant activity of silver nanoparticles reported so far. Many authors declare better antioxidant activity of silver nanoparticles compared to the extract used for synthesis of them. In this review, we focused on methods of antioxidant activity determination in detail to find out novel and perspective techniques to solve the general problems associated with the determination of antioxidant activity of silver nanoparticles.

“…This was because the higher the pH, the more negative NPs surface and the stronger electrostatic attraction between positively charged DOX molecule and the composite surface (Cai et al., 2020). The horse chestnut extract was applied as a capping agent to produce AgNPs, and spherical shape of 50 ± 5 nm and the release of resveratrol reached 45.6% (pH 5.2) and 32.3% (pH 7.4) after 5 hr (Küp et al., 2020). In their experiment, the reducing power of the NPs was stronger than that of the extract, while the DPPH (1,1‐Diphenyl‐2‐picrylhydrazyl) and superoxide radical scavenging activity of the NPs were weaker than that of the extract.…”

Botanic bioactive substances have issues with their solubility, stability, and oral bioavailability in the application, which could be improved by nanotechnologies. In another hands, green synthesis of nanoparticles (NPs) with plant extract is also a promising technology for preparation of NPs due to its safety advantage, yet the bioactive botanic substances that could be more than the assistant of the green synthesis of NPs. Based on the above concerns, this review summarized the preparation of botanic NPs with various plant extract, their solubility, stability, and oral bioavailability; specific attention has been paid to the botanic Ag/Au NPs, their capacity of antioxidant, bioavailability, antimicrobial, anti‐inflammatory, and anticancer.
