“…The particles are in broad size distribution from 15 to 60 nm with average size of 40 nm, as a consequence of the slow rate in the citrate reduction method. The sodium citrate acts as reducing as well as stabilization agent [38,66,67,78]. Moreover, it was confirmed that using the tri sodium citrate in chemical synthesis of silver nanoparticles, the solution was transparent and stable over time (at least 3 months) [62].…”

“…According to the results of microbiological test, the silver NPs noticed a highly antibacterial effect against Escherichia coli and Staphylococcus aureus. It is important to notice that in the form of powders or suspensions, due to the high surface to volume ratio, AgNPs have been used as antibacterial; the main advantages of using AgNPs are related to low toxicity, high efficiency, and low risk of developing resistance and reasonable production cost [38].…”

“…Thus, the way of AgNPs obtains imprint to the nanoparticle different physical, chemical, biologic, and optical properties. The possibilities of AgNP surface to interact with stabilizing agents are depending on their nature; thus, the capping agent can supply new properties of nanoparticles as surface charge, acidity, or basicity in function of pH and susceptibility to ionic strength; consequently, capping agent affects the antimicrobial properties in positive or negative way [38].…”

“…On the other hand, antibacterial properties of silver nanoparticles (AgNPs) have been widely documented . Usually, AgNPs correspond to colloidal systems of Ag0 stabilized by polymers or low‐molecular weight substances . In consequence, immobilization of AgNPs in polymers is an alternative to give intrinsic antibacterial properties by the making of nanostructured systems.…”

Stimuli‐sensitive polymers are a type of smart polymers having the capability to change their configuration or properties under adequate stimuli as heat, pH, magnetic field, mechanical strength, among other. The aim of this work was to synthesize nanostructured polymers with antibacterial properties capable to change their retention properties of divalent metal ions by external stimuli (pH and ionic strength). For that, a polymerizable nanostructured crosslinker (PNC) based on silver nanoparticles (AgNPs) and acrylic acid was synthesized. Later, NPSS was synthesized by free‐radical polymerization, characterized by different analytical techniques and its retention properties of divalent ions (Cu2+, Fe2+, Mn2+, and Zn2+) were studied at different pHs and ionic strengths (5.0, 7.0, and 9.0; and 0.0, 0.5, and 1.5% NaCl, respectively). It was evidenced that AgNPs can be synthesized using acrylic acid as stabilizing agent, and later, be used for synthesis of NPSS by free‐radical polymerization. For NPSS, metal ion retention decreases as pH is increased; in addition, results suggest that the electrostatic interaction is not the only determining factor in the retention of ions. Other possible factors which would be affecting the retention are: water flow by swelling capacity and water flow by osmotic stress resulting of high salt concentration. NPSS showed antimicrobial activity against Escherichia coli and Staphylococcus aureus which was enhanced by incorporation of PNC based on AgNPs. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
