Skin is an important organ of the body due to offering an accessible and convenient site for drug administration. One of the disadvantages of transdermal drug delivery is the low penetration rate of drugs through the skin. Over the past decades, nanoparticles have been used as drug delivery systems to increase therapeutic effects or reduce toxicity. Encapsulation of drugs in nanoparticulate ves...

One of the most challenging efforts in drug delivery is the targeting of the eye. The eye structure and barriers render this organ poorly permeable to drugs. Quite recently the entrance of nanoscience in ocular drug delivery has improved the penetration and half-life of drugs, especially in the anterior eye chamber, while targeting the posterior chamber is still an open issue. The retina and th...

a carrier system based on nanoporous silica (sba-15) with magnetic nanoparticles of cofe2o4 was synthesized via the impregnation of cobalt salt, iron salt and citric acid with as-synthesized sba-15. the obtained samples were characterized by small angle x-ray scattering (saxs), n2 adsorption/desorption, scanning electron microscopy (sem), vibrating sample magnetometer (vsm) and ultraviolet (uv)...
