Mimosa pudica Flower Extract Mediated Green Synthesis of Gold Nanoparticles

Krishnaprabha Mapala and Manjunatha Pattabi
The use of Mimosa pudica flower extract in the synthesis of highly stable gold nanoparticles (AuNPs) is reported here. On treatment of aqueous chloroauric acid with crude aqueous extract of Mimosa pudica flowers, rapid reduction of Au3+ ions at room temperature was observed without the need of any additional reducing or stabilizing agent.

Magnetophoresis of Superparamagnetic Nanoparticles Applied to the Extraction of Lanthanide Ions in the Presence of Magnetic Field

Fernando Menegatti de Melo, Sabrina da Nobrega Almeida, Antonio Domingues dos Santos and Henrique Eisi Toma
Magnetic migration (magnetophoresis) and extraction of Dy3+ ions by magnetite (Fe3O4) nanoparticles functionalized with diethylenetriaminepentaacetic acid (MagNP@DTPA) were probed, using an analytical balance and an external weighing device comprising a miniature neodymium (Nd2Fe14B) magnet and a Lego® system.

Adsorptive Removal of Phenol from Aqueous Solution by Using Carbon Nanotubes and Magnetic BioChar

N. M. Mubarak, N. Sazila, Sabzoi Nizamuddin, E.C. Abdullah and JN Sahu
The effectiveness of phenol removal from aqueous solution by different adsorbents was experimentally studied. Results revealed that the pH and adsorbent dosage to be the main factors in this adsorption study. It is found that functionalized carbon nanotubes (CNTs) give the highest removal of 88% followed by 82.3% and 82.2% for magnetic biochar and raw CNTs respectively.

Magnetotactic Bacteria – Trends for the Future Research

Denis Grouzdev, Veronika Koziaeva, Boris Kuznetsov and Konstantin Skryabin
Magnetotactic bacteria (MTB) are interesting for their ability to produce size-narrowed and chemically pure magnetic nanoparticles, which are the promising new nanomaterial useful for a number of biotech applications – drug delivery, cell sorting, DNA/RNA extraction, etc. The only difficulty hampering the practical recruitment of bacterial magnetosomes is the low level of their production by bacteria.
