In the current study, amine surface modified iron-oxide nanoparticles of 6nm diameter without polymer coating were fabricated in an aqueous solution by organic acid modification as an adherent following chemical coprecipitation. Structure and the superparamagnetic property of magnetite nanoparticles were characterized by selected area electron diffraction (SAED) and superconducting quantum interference...
A newly developed non-polymer coated Fe 3 O 4 nanoparticles showing well-dispersion were synthesized using Fe(II) and Fe(III) salt chemical coprecipitation with tetramethylammonium hydroxide (N(CH 3 ) 4 OH) in an aqueous solution. Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectrometer (FT-IR), X-ray photoelectron spectrometer...
We describe a simple, efficient two-step method for construction of glycoprotein D (gD)-negative pseudorabies virus (PrV) carrying transgenes inserted in place of the gD gene. The first step was the use of the thymidine kinase (TK) gene of herpes simplex virus (HSV) for insertional inactivation of the gD gene in a PrV mutant deficient in both TK and glycoprotein E (gE). The gD-negative, HSV-TK-positive...
