This thesis is devoted to the study of vertical Pourous Anodic Alumina templates (PAA) and the application thereof for nanoorganization and device fabrication. Our principle objective was to develop an anodization method of Al that allows a reproducible fabrication of PAA offering the possibility to create complex porous nanostructures as well as the organization of nanomaterials. The PAA fabri...

PURPOSE The purpose of this study was to investigate the curative effect of bone-like hydroxyapatite/poly amino acid (BHA/PAA) as a carrier for poly(lactic-co-glycolic acid)-coated rifapentine microsphere (RPM) in the treatment of rabbit chronic osteomyelitis induced by Staphylococcus aureus. METHODS RPM was prepared through an oil-in-water emulsion solvent evaporation method, and RPM was com...

چکیده امروزه با توسعه صنایع شیمیایی ،تصفیه فاضلابهای صنعتی یکی از مشکلات اصلی این صنایع می باشد.کارخانه آنتی بیوتیک سازی ایران نیز یکی از این صنایع دارویی می باشد که دارای حجم بالایی از محصولات فرعی و حلالهای آلی است. در سال های اخیر این شرکت در تلاش بوده است تا بتواند جهت بازیافت نمودن بخشی از آن راهکاری پیدا کند. یکی از مواد تولیدی این کارخانه 6- آمینوپنی سیلانیک اسید می باشد که یکی از موا...

The paper is focused on the formation of hydroxyapatite nanoparticles (HAp) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. It is shown that PAA, can be incorporated into the individual inverse microemulsion droplets. The m...

Barium sulphate (BaSO4) precipitation has been suggested to occur by non-classical pathways that include the formation of a dense liquid precursor phase, nucleation of primary nanoparticles and two levels of oriented aggregation resulting in micron-sized barite single crystals. In this study we build from this previous knowledge and explore how Ba and SO4 2− ions associate in solution prior to ...

PURPOSE To investigate the anchoring of plasmid DNA/anti-DNA antibody/cationic lipid tri-complex (DAC micelles) onto bisphosphonate-modified 316 L coronary stents for cardiovascular site-specific gene delivery. METHODS Stents were first modified with polyallylamine bisphosphonate (PAA-BP), thereby enabling the retention of a PAA-BP molecular monolayer that permits the anchoring (via vector-bi...
