Synthesis of Smart Nanocomposites from Chitosan, Functionalized with Gold Nanoparticles and Temperature Sensitive Polymers: Investigation of their Application in Light Responsive Nano Vehicles
, M.Sc. Thesis Sharif University of Technology ; Pourjavadi, Ali (Supervisor)
Abstract
With the fast progress of nanotechnology, targeted drug delivery systems have been widely developed due to decreasing in the drug dosage and subsequently side effects of them into body. These smart systems are able to response to the surroundings stimuli. External stimuli in comparison with internal stimuli are more controllable, and can release drug at the targeted side in the desirable times. In the recent studies, there has been an increasing interest in the usage of LASER as an external stimulus due to high precision, short time response, and suitable practical function. For cancer therapy, several studies have been done by focusing on the hyperthermia effects of gold nanoparticles. In...

Abstract
The oxidation-reduction (redox) responsive micelle system is based on a diselenide-containing triblock copolymer, poly(ε-caprolactone)-bis(diselenide-methoxy poly(ethylene glycol)/poly(ethylene glycol)-folate) [PCL-(SeSe-mPEG/PEG-FA)2]. Resulting in the development of tumor-targeted delivery for hydrophobic anticancer drugs. The diselenide bond, as redox-sensitive linkage, was designed, so it is located at the hydrophilic/hydrophobic hinge to allow complete micelles collapse and efficient drug release, in redox environments. The amphiphilic block copolymers self-assembled into micelles at concentrations above the critical micelle concentration (CMC) in an aqueous environment. Dynamic light...
