The effect of milling process on TiO2 nanopowders and functional properties of TiO2 coated cotton fabric was investigated. The XRD analysis reveals that the milled TiO2 nanopowders reduce its size in Nano scale when milling time increases. SEM analysis reveals that the milled TiO2 powder shows a seed-like structure. FTIR spectra show the presence of […]
Recently, with the increase in diseases caused by bacterial and viral infections, the need for antibacterial agents has widely increased. On the other hand, with the development of drug resistance to organic groups of antibiotics, new antibiotics have attracted the attention of researchers because new methods are needed to reduce the activity of bacteria. Nanotechnology […]
Recently, the synthesis of metal nanocrystallites using plant extracts has received much attention due to its low cost and compatibility with the environment. In this research, copper nanocrystallites were synthesized using hawthorn extract. The formation of copper nanocrystallites was observed by changing the color of the solution. Synthesized copper nanocrystallites were investigated by techniques such […]
In the present study, we have reported the biological synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (PBW343, Triticum durum and Aegilops tauschii )for the reduction of silver ions to silver nanoparticles. Bioreduction of Ag+ to Ag0 was observed when aqueous extract augmented with silver nitrate […]
Zinc Oxide nanoparticles (ZnO-NPs) and graphene carbon material, due to lower drug resistance, can replace antibiotics, and by decorating of graphene with Zn-NPs, their properties can be greatly improved. The purpose of this study was to evaluate the antioxidant and antibacterial effects of ZnO-NPs biosynthesized using Crocus Sativus petal extract, graphene and graphene decorated by […]
The spread of contagious diseases and the increase in the drug resistance amongst pathogens has enforced the researchers to synthesize biologically active nanoparticles. Development of eco-friendly practice for the synthesis of nanoparticles is growing bit by bit in the field of nano-biotechnology. The present investigation outlines the development of a method to biosynthesize copper nanoparticles […]
The advantage of using plants and plant metabolites over expansive and toxic chemical methods for nanoparticles (NPs) synthesis has fascinated researchers to investigate the mechanisms of bio-reduction of metal ion for various biomedical applications. Herein, pineapple leaf extract was used for the synthesis of silver (Ag) and bimetallic silver-gold (Ag-Au) core-shell NPs which offered an […]
The seed extract of Spondia mombins was used in the biofabrication of silver nanoparticles (AgNPs) in this study. The biosynthesized AgNPs was characterised using UV-Vis Spectroscopy, FTIR, FESEM, TEM, XRD and EDX. The antimicrobial efficacy of the synthetized AgNPs was evaluated against certain pathogens. The absorption spectrum peaked at 425 nm when the UV analysis […]
Bactericidal effect of copper oxide is still a growing area of research even though a lot of experiments have been carried out by the researchers. The present work was designed to explore structural and optical properties of micro-size copper oxide particles (µCuO) synthesized using microwave irradiation. Synthesized samples were characterized with ultraviolet-visible spectroscopy, Fourier transform […]
