In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

The aim of this study was to formulate and evaluate microencapsulated controlled release preparations of a highly water/soluble drug, salbutamol sulphate by (water in oil) in oil emulsion technique using ethyl cellulose as the retardant material. Various processing and formulation parameters such as drug/polymer ratio, stirring speed, volume of processing medium were optimized to maximize the e...

Objective(s): Fabricating a biomimetic scaffold platform combined with controlled release of bioactive agents is a practical approach for bone tissue engineering. Controlled delivery of peptides and growth factors which play a significant role in osteogenesis is an important issue reducing the associated adverse effects and leading to cost-effectiveness. Materials and Methods: We develope...

objective(s): researchers have intended to reformulate drugs so that they may be more safely used in human body. polymer science and nanotechnology have great roles in this field. the aim of this paper is to introduce an efficient drug delivery vehicle which can perform both targeted and controlled antibiotic release using magnetic nanoparticles grafted ph-responsive polymer.  methods: fe3o4 na...
