Preparation and characterization of the Cloisite Na+ modified with cationic surfactants

An easy method was used to modify the Cloisite Na+ with different cationic surfactants. To prevent the damages in the clay crystal structure, the process was taken without acid activation. The organo-modified montmorillonite (MMT) were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermal analysis (TG/DTG), field emission scanning electron microscopy ...

Highly Efficient Intracellular Protein Delivery by Cationic Polyethyleneimine-Modified Gelatin Nanoparticles

Intracellular protein delivery may provide a safe and non-genome integrated strategy for targeting abnormal or specific cells for applications in cell reprogramming therapy. Thus, highly efficient intracellular functional protein delivery would be beneficial for protein drug discovery. In this study, we generated a cationic polyethyleneimine (PEI)-modified gelatin nanoparticle and evaluated its...
