The conducting polymers (CPs) are the important materials due to their large surface area, high thermal stability, good conductivity, easy shape, process and properties can be tuned by modifying structures or processing. Few have emerged as potential candidate for determination of a few anti-cancer drugs. In present study, sensing ability Poly-pyrrole (poly-py) has been investigated with withou...

We report a simple approach to fabricate custom-shape microcapsules using hydrogel templates synthesized by stop flow lithography. Cargo-containing microcapsules were made by coating hydrogel particles with a single layer of poly-l-lysine followed by a one-step core degradation and capsule cross-linking procedure. We determined appropriate coating conditions by investigating the effect of pH, i...

Defined aggregates of polymers such as polymeric micelles are of great importance in the development of pharmaceutical formulations. The amount of drug that can be formulated by a drug delivery system is an important issue, and most drug delivery systems suffer from their relatively low drug-loading capacity. However, as the loading capacities increase, i.e., promoted by good drug-polymer inter...

Poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. The aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (PMECA) particles containing 5-aminosalicylic acid (5-ASA). PMECA particles were prepared using the inverse emulsification...

background: drug nano-carriers are one of the most important tools for targeted cancer therapy so that undesired side effects of chemotherapy drugs are minimized. in this area, the use of ultrasound can be helpful in controlling drug release from nanoparticles to achieve higher treatment efficiency. objective: here, we studies the effects of ultrasound irradiation on the release profile of 5-fl...

The objective of this study was to synthesize and characterize particles as a drug-delivery platform for gliomas, a highly advanced and invasive stage of brain tumor with poor prognosis. Poly(aminoethyl methacrylate-co-methyl methacrylate) particles were prepared by suspension polymerization and poly(aminoethyl methacrylate-co-poly(ethylene glycol) methacrylate) particles were prepared by emuls...

Understanding and controlling structural properties of the materials are crucial in materials research. In this paper, we report that crystallinity and crystallographic orientation of Pd nanowires can be tailored by varying the fabrication conditions during electrochemical deposition in polycarbonate ion-track templates. By changing the deposition temperature during the fabrication process, the...

objective(s): irinotecan is a potent anti-cancer drug from camptothecin group which inhibits topoisomerase i. recently, biodegradable and biocompatible polymers such as poly lactide-co-glycolides (plga) have been considered for the preparation of nanoparticles (nps). materials and methods: in this study, irinotecan loaded plga nps were fabricated by an emulsification/solvent diffusion method to...

INTRODUCTION Extensively used polymers in biomedical applications are naturally occurring or synthetic compounds consisting of large molecules obtained from linking of simple monomers. Potential biomedical applications of these polymers include carrier based drug delivery systems, tissue engineering scaffold and cell culture supports [1]. Polymer based drug delivery system can control the rate ...
