synthesis and characterization of magnetite nanoparticles conjugated with peg as a carrier for ciprofloxacin

synthesis and evaluation of chemically-conjugated carbon nanotubes with peg as a drug carrier

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Covalently modified magnetite nanoparticles with PEG: preparation and characterization as nano-adsorbent for removal of lead from wastewater

BACKGROUND Lead is one of the hazardous materials which is associated with pollution and toxicity problems. This paper describes a novel approach for removal of lead from wastewater. Although naked magnetic nanoparticles have been applied for removal of different pollutants from wastewater, there was no research on employment of covalently PEG modified magnetic nanoparticles for such purpose. ...

Preparation and Characterization of PCL-PEG-PCL Copolymeric Nanoparticles as Polymersomes for Delivery Hydrophilic Drugs

Background: A novel drug delivery system using poly (ε-caprolactone) - poly (ethylene glycol) -poly (ε-caprolactone) (PCL-PEG-PCL) was established in this study. Methods: Ceftriaxone (CTX) was encapsulated within PCL-PEG-PCL nanoparticles by a double emulsion technique (w/o/w), leading to creation of ceftriaxone-loaded PCL-PEG-PCL (CTX/PCL-PEG-PCL) polymersomes. The resulting polymersomes...

Folate-Conjugated Gold Nanoparticles (Synthesis, Characterization and Design for Cancer Cells Nanotechnology-based Targeting)

A new folate-conjugated gold nanoparticle (AuNP) has been designed to selectively target the folate receptor that is overexpressed on the surface of tumoral cells. For this purpose, we made 4-aminothiophenol, as a bifunctional linker to react with HAuCl4 in the presence of sodium borohydride and it was binded to the AuNP surface through its thiol group. Then, we conjugated amino-terminated nano...
