Magnetic nanoparticles separation technology is a method for quick and easy extraction biomolecules such as proteins, DNA and RNA. The present work describes total RNA isolation procedure from transformed rose petals in our laboratory using magnetic nanoparticles as a solid phase absorbant. Petals are the main sources of secondary metabolites, i.e. carotenoids, anthocyanins, flavonoids and phen...

In the present study, new multi-components spinel ferrite Zinc doped metallic ferrites are investigated. The synthesized compounds consisting of Zinc copper ferrite nanostructures were developed using the Co-precipitation technique. Powder X-ray diffraction pattern (XRD) confirms the formation of the spinel phase for all the samples. The lattice constant was studied through powder X-ray diffrac...

a new method for the separation and preconcentration of trace amounts of cadmium in food and water samples by magnetic solid phase extraction (mspe) with fe3o4 magnetic nanoparticles (fe3o4-mnps) and its determination by flame atomic absorption spectrometry has been developed. for this purpose, fe3o4-mnps were synthesized via chemical precipitation method. the extraction of cadmium ions from th...

widespread arsenic contamination of mining wastewater of zarshouran (west azerbaijan province) hasled to a massive epidemic of arsenic poisoning in the whole of surrounding areas. it is estimated thatapproximately all agriculture fields are being irrigated with the water that its arsenic concentrationselevated above the world health organization’s standard of 10 parts per billion. a novel advan...

Implantable biosensors were developed for real-time monitoring of pressure and strain in the human body. The sensor, which was wireless and passive, consisted of a soft magnetic material and a permanent magnet. When exposed to a low frequency AC magnetic field, the soft magnetic material generated secondary magnetic fields that also included the higher-order harmonic modes. Parameters of intere...

Magnetic polymer particles have been used in a wide variety of applications ranging from targeting and separation to diagnostics and imaging. Current synthesis methods have limited these particles to spherical or deformations of spherical morphologies. In this paper, we report the use of stop flow lithography to produce magnetic hydrogel microparticles with a graphical code region, a probe regi...

Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation extremely poor, resulting in low-efficiency utilization resources. Here, from VTM ore studied by combining magnetic and flotation technologies. In particular, floatability mixed MOH/PG-1 collectors thoroughly investigated. The results show that a concen...

We present a lattice model to study the equilibrium phase diagram of ordered alloys with one magnetic component that exhibits a low temperature phase separation between paramagnetic and ferromagnetic phases. The model is constructed from the experimental facts observed in Cu32xAlMnx and it includes coupling between configurational and magnetic degrees of freedom that are appropriate for reprodu...
