The aim of the study was to synthesize silver nanoparticles by using filamentous fungus Penicillium sp. The fungal culture was isolated from the soil samples collected from agriculture fields in Vellore district, Tamil Nadu, India. The purified fungal isolates were inoculated in minimal medium and incubated at room temperature for three days. For the synthesis of silver nanoparticles, 50 ml of ...

Polymer nanocomposites incorporating metal or metal oxide nanoparticles have been developed to improve their characteristics (flexibility, gas barrier properties, antimicrobial or antioxidant properties, etc.). Among them silver nanoparticles are used because of their antimicrobial effect in many daily life materials, i.e. food packaging. However, there is not any reference to the migration of ...

Nanotechnology is a field of science which involves the synthesis and applications of nanoparticles. Silver nanoparticles (AgNp) have applications in various fields due to their unique optical, physical, electrical and medicinal properties. In this study, silver nanoparticles were synthesized by biophysical method. Silver nanoparticles were characterized by using UV-Visible absorption spectrosc...

The interaction between silver nanoparticles and viruses is attracting great interest due to the potential antiviral activity of these particles, and is the subject of much research effort in the treatment of infectious diseases. In this work, we demonstrate that silver nanoparticles undergo a size-dependent interaction with herpes simplex virus types 1 and 2 and with human parainfluenza virus ...

Biological synthesis of silver nanoparticles using microorganisms has received profound interest because of their potential to synthesize nanoparticles of various size, shape and morphology. In the current study, synthesis of silver nanoparticles by a bacterial strain (CS 11) isolated from heavy metal contaminated soil is reported. Molecular identification of the isolate showed it as a strain o...

Here we report synthesis of silver nanoparticles using leaf extracts of four varieties of lemongrass (Cymbopogon flexuosus) namely krishna, neema, pragati and suvarna and their antibacterial activities against drug resistant bacteria Staphylococcus aureus, Pseudomonas aeruginosa and Acinatobacter bamunnii. Silver nanoparticles were synthesized by the bio-reduction of silver nitrate solution (1 ...

Preparation of silver nanoparticle by using leaf extracts of Terminalia catappa, its deposition on Nylon fabrics, and the modification with an addition of HDTMS have been conducted in this research. The samples prepared in this study were nylon cloth (N0), nylon cloth silver nanoparticles (N1), Nylon cloth HDTMS (N2), Nylon cloth − silver nanoparticles − HDTMS (N3), and Nylon cloth HDTMS silver...

Silver doped zinc oxide nanoparticles are synthesized by a solution combustion method. The samples characterized by a variety of spectroscopic and other techniques clearly reveal the presence of silver nanoparticles as well as silver clusters. The silver in the two forms was identified by careful deconvolution of X-ray photoelectron spectral results. Their formation was also confirmed by the pr...

Silver nanoparticles have been used in various fields, and several synthesis processes have been developed. The stability and dispersion of the synthesized nanoparticles is vital. The present article describes a novel approach for one-step synthesis of silver nanoparticles-embedded chitosan particles. The proposed approach was applied to simultaneously obtain and stabilize silver nanoparticles ...

Biologically synthesized silver nanoparticles (SNPs) are being widely using in the field of medicine. Extracellular biosynthesis of silver nanoparticles was carried out by using medicinal plant extracts for the reduction of aqueous silver ions in short period. The silver nanoparticles formation was confirmed by the colour change of plant extracts (SNPs) and further confirmed with the help of UV...
