Nanovehicles are a new class of molecular machines consisting of a molecular scale chassis, axles, and wheels, that can roll across solid surfaces with structurally defined directions making them of interest to synthetic chemists, surface scientists, chemical engineers, and the general car enthusiast. In this tutorial review, following a brief introduction to the development of nanomachines, ou...

glioma, as a primary tumor of central nervous system, is the main cause of death in patients with brain cancer. therefore, development of an efficient strategy for treatment of glioma is worthy. the aim of the current study was to develop a srl peptide-coated dendrimer as a novel dual gene delivery system for targeting the lrp receptor, an up-regulated gene in both bbb and glioma cells. to perf...

Real-time diagnosis and monitoring of disease development, and therapeutic responses to treatment, are possible by theranostic magnetic resonance imaging (MRI). Here we report the synthesis of a multifunctional liposome, which contains Gd-DOTA (an MRI probe), paclitaxel and c(RGDyk) (a targeted peptide). This nanoparticle overcame the insolubility of paclitaxel, reduced the side effects of FDA-...

intravitreal injection is the most common approach for drug delivery to the posterior segment in humans. however, following the injection, drugs are rapidly eliminated from the vitreous, with half-lives up to a few days. depending on the rate of clearance from the vitreous, large boluses and frequent administrations may be required to ensure therapeutic levels over an extended period of time. m...

objective (s): transdermal preparations for testosterone are becoming popular because of their unique advantages such as avoidance of first-pass effect, convenience, improved bioavailability, and reduction of systemic side effects. a novel testosterone transdermal delivery system (tdds) was developed using a palm oil base called hamintm (a commercial product) and tested using in vitro and in vi...
