Preparation and release kinetics of carboxymethyl chitosan/cellulose acetate microspheres as drug delivery system

21-Mar-2015 | Hui Yun Zhou, Pei Pei Cao, Jun Bo Li, Fa Liang Zhang, Pei Pei Ding, Journal of Applied Polymer Science, 2015

ABSTRACT Carboxymethyl chitosan, a water soluble chitosan derivative, was prepared from chitosan using monochloroacetic acid. Carboxymethyl chitosan/cellulose acetate microspheres (CCM) were prepared using the method of W/O/W and emulsification solvent evaporation as drug delivery system. The ...

Exploiting the Lactose–GM3 Interaction for Drug Delivery

20-Mar-2015 | Raghavendra Vasudeva Murthy, Harikrishna Bavireddi, Madhuri Gade, Raghavendra Kikkeri, ChemMedChem, 2015

Abstract Protein–protein and protein–carbohydrate interactions as a means to target the cell surface for therapeutic applications have been extensively investigated. However, carbohydrate–carbohydrate interactions (CCIs) have largely been overlooked. Here, we investigate the concept of ...

Fabrication and Characterization of Chitosan and Pectin Nanostructured Multilayers

17-Mar-2015 | Laura Pastorino, Svetlana Erokhina, Carmelina Ruggiero, Victor Erokhin, Paola Petrini, Macromolecular Chemistry and Physics, 2015

Chitosan has been used for drug delivery applications for many years, and pectin has been recently used for several biomedical applications too. Both chitosan and pectin have shown to possess mucoadhesive properties. We report the assembly and characterization of biocompatible and biodegradable ...

Implantable hydrogel embedded dark-gold nanoswitch as a theranostic probe to sense and overcome cancer multidrug resistance [Medical Sciences]

17-Mar-2015 | João Conde; Nuria Oliva; Natalie Artzi, Proceedings of the National Academy of Sciences current issue, 2015

Multidrug resistance (MDR) in cancer cells is a substantial limitation to the success of chemotherapy. Here, we describe facile means to overcome resistance by silencing the multidrug resistance protein 1 (MRP1), before chemotherapeutic drug delivery in vivo with a single local application. Our ...

Quantum Dot Surface Chemistry and Functionalization for Cell Targeting and Imaging

13-Mar-2015 | Regina Bilan; Fabrice Fleury; Igor Nabiev; Alyona Sukhanova, Bioconjugate Chemistry, 2015

Quantum dots (QDs) are highly fluorescent nanoscale crystals with size-dependent emission spectra. Due to their excellent photophysical properties, QDs are a promising alternative to organic fluorescent dyes and fluorescent proteins for cell targeting, imaging, and drug delivery. For biomedical ...
