Carbon quantum dots (CQDs), unlike semiconductor quantum dots, possess fine biocompatibility, excellent upconversion properties, high photostability and low toxicity. Here, we report multifunctional CQDs which were developed using alginate, 3% hydrogen peroxide and double distilled water through a facile, eco-friendly and inexpensive one-step hydrothermal carbonization route. In this reaction, the...
A new gene vector, cationized Lycium barbarum polysaccharides (cLBP) nanoparticles, prepared with different amine compounds for non-viral delivery of plasmid DNA encoding for transforming growth factor beta 1 (TGFβ-1) was developed and the efficiency of these nanoparticles to transfect rat mesenchymal stem cells in vitro was determined. The spherical cLBP-plasmid TGFβ-1 nanoparticles were 160–330nm...
