Synthesis of silver nanoparticles by chemical and biological methods and their antimicrobial properties

Abstract: Biogenic synthesis of nanoparticles offers an attractive alternate to chemical synthesis methods. Various hazard free, eco-friendly methods of synthesis of silver nanoparticles are in operation. In chemical reduction methods, the reducing agent is a chemical solution, whereas in biological ones, the collection of enzymes, especially nitrate reductase, plays this role. The highest antibacterial activity of silver nanoparticles synthesised by chemical and biological methods was found in Staphylococcus aureus and Escherichia coli. The paper aims to discuss some fundamental issues about non-biological methods and benefits about biological methods for silver nanoparticles synthesis and their antibacterial studies.

Preparation and characterisation of lignin nanoparticles: evaluation of their potential as antioxidants and UV protectants

Abstract: Lignin, an abundant plant biopolymer, is known to possess antioxidant and UV protectant properties in its native state. Nanoparticles exhibit either improved or different properties corresponding to their bulk materials or parent polymers. In the present study, using nanoprecipitation method, dioxane lignin nanoparticles (DLNP) and alkali lignin nanoparticles (ALNP) are fabricated from two different sources of lignin, i.e., hardwood dioxane lignin (DL) extracted from subabul stems and softwood alkali lignin (AL) which is available as a commercial source. Both DLNP and ALNP were fabricated in spherical shape with mean size of 80–104 nm. Analysis of radical scavenging activity revealed that both DLNP and ALNP possess higher antioxidant activity when compared with their parent polymers DL and AL, respectively. UV protectant potential of DLNP and ALNP was validated by monitoring the survival rates of Escherichia coli upon UV-induced mortality. DLNP and ALNP were more efficient than DL and AL in protecting E. ...

Ultrafine dispersed CuO nanoparticles and their antibacterial activity

Abstract: Copper oxide nanoparticles with a particle size ranging from 80 to 160 nm were prepared by a wet chemical procedure. Copper carbonate hydroxide and sodium hydroxide were used as raw materials. Copper hydroxide was generated as a precursor which was thermally decomposed to CuO nanoparticles. The nanoparticles were characterised using atomic force microscopy, X-ray diffraction and UV-visible spectrometry. The nanoparticles were tested for antibacterial activity against Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella paratyphi and Shigella strains.

NO2 and humidity sensing characteristics of few-layer graphenes

Abstract: Sensing characteristics of few-layer graphenes for NO2 and humidity have been investigated with graphene samples prepared by the thermal exfoliation of graphitic oxide, conversion of nanodiamond (DG) and arc-discharge of graphite in hydrogen (HG). The sensitivity for NO2 is found to be highest with DG. Nitrogen-doped HG (n-type) shows increased sensitivity for NO2 compared with pure HG. The highest sensitivity for humidity is observed with HG. Sensing characteristics of graphene have been examined for different aliphatic alcohols and the sensitivity is found to vary with the chain length and branching.
