In this study, we first investigated changes seen in electrical and optical properties of a polymer light-emitting diode due to using different kinds of solvents and their mixture. Two-layer light emitting diodes with organic small molecules doped in a PVK polymer host were fabricated using (i) non-aromatic solvent chloroform with a high evaporation rate; (ii) aromatic solvent chlorobenzene wit...

In the last several decades, cardiovascular diseases (CVDs) have emerged as a major hazard to human life and health. Conventional formulations for treatment of CVD are available, but they far from ideal because poor water solubility, limited biological activity, non-targeting, drug resistance. With advancement nanotechnology, novel delivery approach CVDs has emerged: nano-drug systems (NDDSs). ...

In this study, we investigated the effects of temozolomide (TMZ)/Poly (lactide-co-glycolide)(PLGA)/nano-hydroxyapatite microspheres on the behavior of U87 glioma cells. The microspheres were fabricated by the "Solid/Water/Oil" method, and they were characterized by using X-Ray diffraction, scanning electron microscopy and differential scanning calorimetry. The proliferation, apoptosis and invas...

linear–dendrite copolymers containing hyper branched poly(citric acid) and linear poly(ethylene glycol) blocks pca–peg–pca are promising nonmaterial to use  in nanomedicine. to investigate their potential application in biological systems (especially for drug carries) oniom2 calculations were applied to study the nature of particular interactions between drug and the polymeric nanoparticles.  b...

The world is facing immense challenges in terms of food security, due to the combined impacts ever-increasing population and adversity climate change. In an attempt counteract these factors, smart nutrient delivery systems, including nano-fertilizers, additives, material coatings, have been introduced increase productivity meet growing demand. Use nanocarriers agro-practices for sustainable far...

Development of delivery systems for new drug for its safe and effective delivery it into the body is an integral part of drug research program. This is particularly true due to increased incidence of adverse pharmacokinetic behavior of new drugs developed recently. Alternative delivery systems have been researched extensively not only to modulate their kinetic behavior in the body but also to a...

The study examined surface adsorption of fullerene C60 with anticancer drug procarbazine in gas and solvent (water) phases using the DFT method. In doing so, the structure of the procarbazine, fullerene and their derivatives were first geometrically optimized in three different configurations with a base set of 6-31 g * and B3LYP hybrid functions. Then, IR calculations, frontier molecular orbit...
