In this work we investigate the characteristics and feasibility of a new class magnetic particles that are optimized for possible biological applications as hyperthermia. These nanostructures have nanoring shape, being composed iron oxides (magnetite or hematite). Such morphology gives nanoparticles peculiar behavior due to their vortex state. The oxide nanorings were obtained using hydrotherma...

background: chitosan nanoparticles have become of great interest for nanomedicine, biomedical engineering and development of new therapeutic drug release systems with improved bioavailability, increased specificity and sensitivity, and reduced pharmacological toxicity. the aim of the present study is to synthesis and optimization of chitosan nanoparticles for industrial and biomedical applicati...
