Abstract

FeCo nanoparticles were synthesized by a solvothermal method, and could work as a fuel-free magneto-controllable carrier to load biocatalytically-active cargo for magneto-controllable and recyclable biocatalysis.

Ethanediamine magnetite nanoparticles (EDAMPs) were used as adsorbents to isolate genomic DNA from various bean-species. A "single-pot" preparation of EDAMPs was described. Further characterization, including transmission electronic microscopy (TEM), scanning electronic microscopy (SEM), thermo-gravimetric analysis (TGA), X-ray powder diffraction (XRD) and Fourier Transform Infrared Spectrophotometer (FT-IR) were used to demonstrate the efficiency of this simple and general identification method. The EDAMPs provided excellent yields of genomic DNA. The isolated DNAwas suitable for use in further applications by the Polymerase Chain Reaction (PCR) for the detection of Genetically Modified (GM) food and non-GM food. The EDAMPs are effective for bioseparation applications.
