Resistance to aspirin and its cytotoxicity significantly limits its therapeutic applications. Nano-liposomal encapsulation of aspirin can reduce its cytotoxicity. In this study, aspirin encapsulated nano-liposomes (AS-NL) was prepared and its performance in drug delivery and cytotoxicity was evaluated. The effects of two independent variables including: number of freeze/thawing cycles and conce...

Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) s...

nanotechnology has changed our lives dramatically and influenced every sector of the research, engineering and also business community. nanotechnology is a rapidly growing science of producing and utilizing nano-sized particles, that measure in nanometer. in other words, nanotechnology is the art of characterizing, manipulating and organizing matter systemically, at the nanometer scale, which h...

Based on the antimicrobial action of nano-silver, a number of “active” FCMs have been developed that are claimed to extend the shelf-life of food by inhibiting the growth of microorganisms. As commercialization of nano-silver grows, the public and the governments become more concerned about the safety and environmental effects of the widespread use of products containing nano-silver [2]. Severa...

BACKGROUND Drug delivery in polymeric micelles combined with tumor irradiation by ultrasound results in effective drug targeting, but this technique requires prior tumor imaging. A technology that combined ultrasound imaging with ultrasound-mediated nanoparticle-based targeted chemotherapy could therefore have important applications in cancer treatment. METHODS Mixtures of drug-loaded polymer...

One never forgets the sheer excitement of an infant's first hesitant steps; the clumsy but undaunted efforts that you know will soon develop to the confident strides that will enable entry to the 'real world'. It is hard to avoid similar thoughts when one looks at the steps currently taken to achieve movement at the nanoscale. In a nano-world where thermal Brownian motion rules, finding movemen...
