Bio-inspired perylene diimide coated super paramagnetic nanoparticles for the effective and efficient removal of lead(ii) from aqueous medium

Evaluation of Cr (VI) ion removal from aqueous solution by bio-inspired chitosan-clay composite: Kinetics and isotherms

This paper reports the evaluation of adsorbing Cr (VI) ions on sorbent prepared from chitosan (CHT), a versatile derivative of chitin, and dodecyl amine modified locally available kaolinite clay (Bijoypur clay) (MC) that has excellent mechanical properties and great resistance to chemical and biological attack. The effect of the initial metal ion concentration, solution pH, contact time, and ad...

Adsorptive Removal of Reactive Orange 122 from Aqueous Solutions by Ionic Liquid Coated Fe3O4 Magnetic Nanoparticles as an Efficient Adsorbent

  In the present investigation, a novel adsorbent, ionic liquid modified magnetic nanoparticles (IL-Fe3O4), was successfully synthesized and characterized by FT-IR spectroscopy, ThermoGravimetric Analysis (TGA), XRD analysis, Scanning Electron Microscopy (SEM) and theory of Brunauer, Emmett, and Teller (BET) for remo...

Polyethyleneimine-modified super paramagnetic Fe3O4 nanoparticles: An efficient, reusable and water tolerance nanocatalyst.

A novel magnetically immobilized polyethyleneimine (PEI) fabricated by covalently anchoring on silica coated Fe3O4 nanoparticles (PEI@Si-MNPs) was prepared. The synthesized catalyst was characterized by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). The immobili...

In vitro Labeling of Neural Stem Cells with Poly-L-Lysine Coated Super Paramagnetic Nanoparticles for Green Fluorescent Protein Transfection

Background: The magnetic nanoparticle-based transfection method is a relatively new technique for delivery of functional genes to target tissues. We aimed to evaluate the transfection efficiency of rat neural stem cell (NSC) using poly-L-lysine hydrobromide (PLL)-coated super paramagnetic iron oxide nanoparticles (SPION). Methods: The SPION was prepared and coated with PLL as transfection agent...
