“…The chitosan medium increase the efficiency of the antimicrobial activity of copper oxide nanoparticles against Gram negative, Gram positive organisms that indicated by the zones of inhibition as shown in Table.3, it was observed that zones of inhibition against Gram negative and gram positive bacteria for CuO nanoparticles with Chitosan at concentration 1%, 2%, 3%, and 5% respectively was higher than zones of inhibition of CuO nanoparticles or chitosan alone, that agreement with study demonstrated that copper oxide nanoparticles embedded within polypropylene exhibiting stronger antimicrobial activity than metal copper nanoparticles 47 as coatings based on copper / polymer which called ex situ, the matrix is act as dispersion medium and the polymer incorporated into the synthesized cupper nanoparticles to develop antimicrobial activity 48,49 . The mechanisms for the antimicrobial behavior of metal/polymer nanocomposites based on thermoplastic matrices explained by the adsorption of bacteria on the polymer surface that cause water to be diffused through the polymer matrix leading to corrosion processes and release of metal ions and water that dissolved in oxygen to the metal/polymer nanocomposite surface causing destroy bacterial membrane 25,50,47,51,30 .…”

Development of nanotechnology, nanoparticles based product and its application is generating interest of many researchers due to its promising biological achievement. However, it is well known that inorganic nanomaterials are good antimicrobial agents. Among the various nanoparticles, metal nanoparticles as copper assume special importance due to its low cost and easy availability. In this study, the green synthesis method as eco-friendly approach is used to produce biologically copper oxide nanoparticles from Ficus carica leaf extract, stable CuO NPs were formed. The synthesized nanoparticles is characterized through the UV-Vis Spectrophotometer as it found to be 437 nm, Transmission Electron microscopy (TEM) investigated particle sizes in the range 51-62 nm and typical XRD patterns of the formed CuO NPs with high phase purity were obtained. Chitosan stabilizer as naturally occurring polymers was added to the prepared copper nanoparticles in different amounts to obtain Chitosan-CuO with different CuO percentage for longterm stability, for prevention the agglomeration of nanoparticles and enhancing their antibacterial efficacy. FTIR spectroscopy analysis was performed to copperoxide nanoparticle, chitosan, copperoxide chitosan composite to confirm that CuO nanoparticle was mixed with polymer. The antibacterial efficacy of chitosan, copper nanoparticles alone was studied against 22 bacterial pathogen like Coaggulase +ve S. aureus, methicillin-resistant Coaggulase -ve S. aureus, Klebsiella pneumonia as gram positive bacteria, Escherichia coli, e.coli o157 Salmonella typhi, Pseudomonas aeruginosa as gram negative bacteria that showed antibacterial activity against Gram positive as well as Gram negative bacteria. Antimicrobial activities of polymer/metal composites (Co oxide-chitosan nanoparticle) is studied against the same bacterial pathogen. The effect of the prepared Chitosan-CuO composite on ultrastructure of bacterial cells were evaluated by scanning electron microscopy (SEM), it was found that the antibacterial activity of Cu-chitosan nanoparticle composite is more greater than antibacterial activity of copper nanoparticles and chitosan alone that indicate the addition of chitosan stabilizer enhance at great extent the antimicrobial activity of CuO NPs.

“…Metal particles, mainly silver and copper, or mineral fillers functionalized by antibacterial polymers are then relevant. [6][7][8] The antibacterial activity of silver ions has been well known since ancient times. 9,10 It has been particularly demonstrated that, in low concentrations, silver is non-toxic to human cells.…”

Silver nanoparticles were prepared by microwave irradiation of a silver nitrate (AgNO 3 ) aqueous solution in poly(ethylene glycol) (PEG) in the absence of other chemicals. Optimal monodispersed, stable and spherical silver nanoparticles with 35 ± 5 nm diameter were obtained after 20 min of microwave irradiation at 120 1C in the presence of PEG 2000. Polyurethanes (PUs) containing silver (Ag) nanoparticles (35 nm, 1 Â 10 À3 -3 Â 10 À3 wt-%) were then prepared by introducing the nanoparticles suspension at different times of the waterborne PU synthesis. The Ag nanoparticles were found to be well dispersed in PU when introduced initially with the reagents. In these conditions, the PEG was well chemically linked to the PU chains and the presence of Ag nanoparticles didn't impact the thermo-mechanical properties of the PU. The prepared silver nanoparticles exhibited biocidal properties against Pseudomonas aeruginosa and Enterococcus faecalis both in liquid suspension and on the PUs surfaces.

“…Biocidal polymers can be prepared by the incorporation of a biocide agent into bulk polymers during processing of the material or by endowing a biocidal function to the polymer after processing, for example, applying surface coatings containing the agent. [3][4][5][6] A different approach is the polymerization of monomer-containing biocide groups or its copolymerization with another monomer producing a new family of polymers bearing biocidal agents. [3] The grafting of antimicrobial agents into the polymers is yet another approach to prepare bioactive materials.…”

A set of poly(propylene) composites containing different amounts of copper nanoparticles (CNP) were prepared by the melt mixed method and their antimicrobial behavior was quantitatively studied. The time needed to reduce the bacteria to 50% dropped to half with only 1 v/v % of CNP, compared to the polymer without CNP. After 4 h, this composite killed more than 99.9% of the bacteria. The biocide kinetics can be controlled by the nanofiller content; composites with CNP concentrations higher than 10 v/v % eliminated 99% of the bacteria in less than 2 h. X-ray photoelectron spectroscopy did not detect CNP at the surface, therefore the biocide behavior was attributed to copper in the bulk of the composite.
