Study Data from National Center for Nanoscience and Technology Update Knowledge of Gene Therapy

February 6, 2014

By a News Reporter-Staff News Editor at Gene Therapy Weekly -- Investigators publish new report on Biotechnology. According to news reporting originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "Carbon dots (CD) are luminescent nanomaterial with unique properties that show great potential in many applications. Herein, branched polyethyleneimine-based carbon dots (PCD) are prepared from branched polyethyleneimine by oxidation and a modified hydrothermal reaction."

Our news editors obtained a quote from the research from National Center for Nanoscience and Technology, "Structure and composition analysis indicate that obtained PCD possesses a 3-4 am in diameter and a graphitic structure with lattice spacing of 0.30 nm. The PCD has a quantum yield of 54.3%. The bright photoluminescence shows that it can be used for cell imaging. The PCD exhibits extremely good biocompatibility and can be applied for gene delivery."

According to the news editors, the research concluded: "Because of its specific nanostructure and photoluminescence property the multifunctional PCD prepared shows potential for applications in bioimaging and gene delivery."
