Microfluidic systems can accelerate clinical translation of nanoparticles due to their ability to generate nanoparticles in a well-controlled and reproducible manner. In this study, a single-step process based on microfluidic focusing (MF) was employed to synthesize transferrin-conjugated lipid nanoparticles (Tf-LNPs) and the method was compared with a(More)
Polyethylenimine (PEI) as a cationic polymer is commonly used as a carrier for gene delivery. PEI-800 is less toxic than PEI-25K but it is also less efficient. A novel nanocarrier was developed by combining PEI-800 with a pH-sensitive lipid to form polymer-lipid hybrid nanoparticles (P/LNPs). They were synthesized by microfluidic focusing (MF). Two(More)
Cationic liposomes incorporating stearic acid-modified octa-arginine (StA-R8) were evaluated for survivin small interfering RNA (siRNA) delivery. StA-R8 was synthesized and incorporated into liposomes. The composition of liposomes was optimized. Physicochemical properties, cytotoxicity, cellular uptake and gene silencing activity of the liposomes complexed(More)
Clinical development of siRNA has been hindered by the lack of an effective delivery system. Here, we report the construction of a novel siRNA delivery system, sTOLP, which is based on cell penetrating peptide oleoyl-octaarginine (OA-R8) modified multifunctional lipid nanoparticles. sTOLP nanoparticles are composed of a protamine complexed siRNA core,(More)
