In this paper, a folate-PEG coated polymeric liposome (FPL) formed from octadecyl-quaternized lysine modified chitosan (OQLCS) and cholesterol has been prepared successfully. The OQLCS and its… (More)
In this paper, based on selecting the appropriate type of quantum dots (QDs), a novel method is developed to enhance the quantum yield (QY) of silica-coated QD nanoparticles (SQDNPs). The effect of… (More)
Chemotherapy is one of the most effective approaches to treat cancers in the clinic, but the problems, such as multidrug resistance (MDR), low bioavailability and toxicity, severely constrain the… (More)
Due to the existence of the blood-spinal cord barrier (BSCB), many therapeutic macromolecular agents, such as drugs, protein and gene, cannot pass through this barrier to reach the site of injury,… (More)
A facile strategy is reported here for synthesis of Zn-Cu-In-S/ZnS (ZCIS/ZnS) core/shell QDs to address the synthetic issues that the unexpected blue-shift of CuInS(2)-based nanocrystals. In this… (More)
Functionalized quantum dots (QDs) have been widely explored for multimodality bioimaging and proven to be versatile agents. Attaching positron-emitting radioisotopes onto QDs not only endows their… (More)
The design and construction of effective delivery vectors for drugs is very important. We have discovered that octadecyl quaternized carboxymethyl chitosan (OQCMC) in combination with cholesterol… (More)
Golgi complexes (Golgi) play important roles in the development and function of neurons [1-3]. Not only are Golgi present in the neuronal soma (somal Golgi), they also exist in the dendrites as Golgi… (More)
Polyamidoamine (PAMAM) dendrimer and Tat peptides were conjugated to bacterial magnetic nanoparticles (BMPs) for the construction of an efficient and targeted gene delivery system with transmembrane… (More)

Paclitaxel has fared poorly in clinical trials against brain glioma. We hypothesized that superparamagnetic nanocarriers may enhance its bioactivities by delivering it into the brain.
