A one step method for isolation of genomic DNA using multi-amino modified magnetic nanoparticles

Magnetic controlling of migration of DNA and proteins using one-step modified gold nanoparticles.

A protocol was developed for preparing magnetic gold nanoparticles via one-step modification with a paramagnetic cationic surfactant. These magnetic gold nanoparticles can bind to and manipulate a low strength magnetic field-based delivery of DNA and proteins powerfully and non-invasively.

One-pot Multi-step Synthesis of some Aromatic Salicylaldoximes Using MgO Nanoparticles

MgO nanopartticels (NP-MgO) in average size between 30—130 nm were prepared by sonochemistry method. Some phenols have been converted to ortho-hydroxybezaldehyd by ortho-formylation using MgO nanoparticles and (CH2O)n in xylene and subsequently treated with aqueous NH2OH.HCl, affording the corresponding aldoxime in a one-pot procedure. Moreover, this one-pot process, with two transformations, o...

A Modified Multi Time Step Integration for Dynamic Analysis

In this paper new implicit higher order accuracy (N-IHOA) time integration based on assumption of constant time step is presented for dynamic analysis. This method belongs to the category of the multi time step integrations. Here, current displacement and velocity are assumed to be functions of the velocities and accelerations of several previous time steps, respectively. This definition causes...

Ammonia-mediated Method for One-step and Surfactant-free Synthesis of Magnetite Nanoparticles

Magnetite (Fe3O4) nanoparticles have been successfully prepared by a novel one-step and surfactant-free approach utilizing ferrous ion, as a single iron source. In this manner, the reaction occurs between two aqueous solutions via the spontaneous transfer of ammonia gas from one to another in room temperature. No ferric source or oxidizing specie, oxidation controlling and capping agents are ne...
