We have developed a sensitive electrochemical sensor for Organophosphorus pesticide methyl parathion (MP) using silver particles supported graphene nanoribbons (Ag@GNRs). The Ag@GNRs nanocomposite was prepared through facile wet chemical strategy and characterized by TEM, EDX, XRD, Raman, UV-visible, electrochemical and impedance spectroscopies. The Ag@GNRs film modified screen printed carbon e...

In this work, the antimicrobial property of nanocomposite prepared by loading of silver nanoparticle onto activated carbon (AgNP-AC) was studied. The silver nanoparticles were synthesized biologically from the culture Enterobacter aerogenes and loaded onto the activated carbon. The nanoparticle and nanocomposite were characterized by UV-vis, scanning electron microscopy and X-ray diffraction st...

A nanocomposite of silver nanoparticles and reduced graphene oxide (Ag/rGO) has been developed as a catalyst for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with sodium borohydride, owing to the larger specific surface area and synergistic effect of rGO. A facile and rapid microwave-assisted green route has been used for the uniform deposition of Ag nanoparticles and the reduc...

Objective(s): Antibacterial and antifungal nanocomposites are widely used in food packaging and pharmaceutical and medicine industries. Among the polymers of these nanocomposites, epoxy coatings are commonly used for health and industrial applications. The present study aimed to synthesize CuO nanoparticles using the chemical reduction method and characterized them by ultraviolet-visible (UV-Vi...

A nanocomposite of silver nanoparticles/reduced graphene oxide (Ag/rGO) has been fabricated as a surface-enhanced Raman scattering (SERS) substrate owing to the large surface area and two-dimensional nanosheet structure of rGO. A facile and rapid microwave-assisted green route has been used for the formation of Ag nanoparticles and the reduction of graphene oxide simultaneously with L-arginine ...

Pectin-Ag nanocomposites with a core-shell structure are synthesized by the “green chemistry” method based on reduction of silver nitrate pectin (amidated, low-, or high methoxylated) in an alkaline medium at room temperature. TEM and DLS measurements show that average size inorganic core (10–30 nm) hydrodynamic diameter nanocomposite (284.8–649.2 depend type pectin. The films pectin-Ag polyvin...

nanocomposite composed of organoclay(cloisite 20a-c20a) and poly lactic acid (pla) was prepared by solvent casting method. physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. x-ray diffraction (xrd) patterns and scanning electron microscopy (sem) images revealed that the diffraction peak of nanoclay shifted to lower angles and the d-spacing betwee...

Nano packaging is currently one of the most important topics in food packaging technologies. The aim of the application of this technology in food packaging is increasing shelf life of foods by preventing internal and external corruption and microbial contaminations. Use of silver nanoparticles in food packaging has recently attracted much attention. The aim of this study was to investigate the...

The field of manufacturing technology has totally been renovated with the emergence of nanotechnology; and the mergence of nanoscience with material science, biology, biotechnology and medicine has completely novelized various arrays of biomedical engineering. For the nanomedicine landscape we have designed and developed Ag/CS-PVC nanocomposite material having superb antimicrobial properties wh...

The antimicrobial activity of silver nanoparticles (AgNPs) is currently used as an alternative disinfectant with diverse applications, ranging from decontamination of aquatic environments to disinfection of medical devices and instrumentation. However, incorporation of AgNPs to the environment causes collateral damage that should be avoided. In this work, a novel Ag-based nanocomposite (CEOBACT...
