Chitosan-based nanomaterials for drug delivery and antibiotic-free bacterial control

, , , , , , , , , , , , , , , ,
Research focused on chitosan (CS)-based nanostructured materials has burgeoned in the past decade or so, particularly in the biosciences and bionanotechnology fields. Chitosan characteristics (Mw and degree of acetylation), as well as the processing conditions [...]

Supramolecular assemblies of cisplatin and polyelectrolytes: preparation, characterization and activity against cancer cells

, , , , , ,
Nanoformulation of cisplatin (Cis) is important to circumvent its high toxicity against normal cells. In this work, Cis cationic nanoparticles were prepared by the self-assembly of drug and oppositely charged polyelectrolytes (carboxymethylcellulose, CMC; chitosan, CH; [...]

Stability of Functionalized Magnetic Particles in a Physiologic Fluid

, , , , , , ,
Magnetic materials are widely used in biomedical applications such as magnetic separation, magnetic resonance imaging, drug delivery and hyperthermia. In these applications the nanoparticles are functionalized in a core/shell type with polymeric materials which contains [...]
