nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. importance of the magnetic nanomaterials in biomedical science cannot be overlooked. the most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. however monodispersion, selection of an appropriate coati...

objective(s):  biosynthesis of gold nanoparticles (ngps) is environmentally safer than chemical and physical procedures. this method requires no use of toxic solvents and synthesis of dangerous products and is environmentally safe. in this study, we report the biosynthesis of ngps using streptomyces djakartensis isolate b-5.   materials and methods: ngps were biosynthesized by reducing aqueous ...

In this final contribution we summarize the current status and achievements of the SWS Challenge, present the perspectives and future steps, and summarize the lessons learned so far both concerning this Challenge and the non-competitive problem driven comparison of approaches in general, as for instance in the context of other initiatives with a similar spirit (like the jETI-FMICS and Bio-jETI ...

SnCl4/nano-sawdust was prepared as a carbohydrate-based catalyst containing of tin bearing cellulose units. The catalyst was characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDS). The catalyst was applied successfully as a readily available, inexpensive, biodeg...

Background: Developing effective methods for the synthesis of bio-compatible and non-toxic nanoparticles is the main goal of nanotechnology. In the most chemical methods, a chemical reducing agent is used to reduce metal ions. But, in chemical methods, the stability of nanoparticles is controversial and synthesis in large sizes is much more difficult. Moreover, there is an incr...

α-amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2zncl2 as a bio lewis acidic ionic liquid. mild lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.

Schwertmannite, a kind of iron oxyhydrosulfate mineral, can removal arsenic(III) from arsenic(III)-bearing groundwater by the adsorption process. In this study, schwertmannite was bio-synthesized by Acidithiobacillus ferrooxidans LX5 in shaking flasks (160 rpm) containing a 0.16 mol/L FeSO4 liquid solution. After bio-synthesis, 25.5% of the bio-synthesized schwertmannite adhered to the reactor ...

Biological systems offer more than an inspiration for the spontaneous hierarchical organization of matter at length scales between 1 and 1000 nm. They also provide useful principles and molecular building blocks that have recently emerged with the proven ability to generate extended three-dimensional structures of hybrid biotic/abiotic components arranged with molecular precision. These princip...
