Uniform polypyrrole (PPy) nanoparticles are fabricated from a facile one-step aqueous dispersion polymerization. Owing to their high photothermal conversion efficiency and photostability compared with the well-known Au nanorods, as well as their good colloidal stability and biocompatibility, the resulting PPy nanoparticles can used as a novel promising(More)
A nanotheranostic agent has been readily fabricated by encapsulating tantalum oxide (TaOx) nanoparticles (NPs) into polypyrrole (PPy) NPs via a facile one-step chemical oxidation polymerization for bimodal imaging guided photothermal ablation of tumor. It was proved that the obtained composite nanoparticles (TaOx@PPy NPs) with an average diameter around 45(More)
Electrospinning of natural polymer nanofibers useful for biomedical applications often requires the use of cytotoxic organic solvents. In this study, gelatin nanofibers are electrospun from phosphate buffer saline/ethanol binary mixtures as a benign solvent at ambient temperature. The influences of ionic strength, ethanol concentration, and gelatin(More)
Imaging guided ablation therapy has been applied in both biomedical research and clinical trials and turned out to be one of the most promising approaches for cancer treatment. Herein, the multifunctional nanocapsules were fabricated through loading perfluorooctylbromide (PFOB) and superparamagnetic iron oxide nanoparticles (SPIOs) into poly(lactic acid)(More)
The therapeutic application of small interfering RNA (siRNA) requires safe nanocarriers for specific and efficient delivery in vivo. Herein, PEGylated cationic cerasomes (PCCs) were fabricated by doping a cationic lipid with a hydroxyl group into nanohybrid cerasomes. Multiple properties of PCCs provide a solution to many of the limitations associated with(More)
Novel biocompatible nanobubbles were fabricated by ultrasonication of a mixture of Span 60 and polyoxyethylene 40 stearate (PEG40S) followed by differential centrifugation to isolate the relevant subpopulation from the parent suspensions. Particle sizing analysis and optical microscopy inspection indicated that the freshly generated micro/nanobubble(More)
A biodegradable nanotheranostic agent has been successfully constructed for fluorescence/magnetic resonance dual-modal imaging guided photothermal therapy by loading indocyanine green (ICG) molecules into 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy (polyethylene glycol)] (DSPE-PEG) coated superparamagnetic iron oxide (SPIO) nanoparticles(More)
Aiming at the enhancement of the physicochemical stability as well as the sustained-release property of conventional liposomes, a novel polymerized vesicular carrier, 10,12-pentacosadiynoic acid (PCDA) vesicles, loaded with paclitaxel as a model hydrophobic drug has been successfully constituted by incorporation of a polymerizable diacetylene into the lipid(More)
