Understanding Magnetic Nanopactlets

Composition andProperties

Magnetic nanopaterles are typically composted of iron oxide cores, such as magnetite (Fe mean O mean maghemite (γ- Fe mean O mean), which exhibit strong superparagnetic behavior at room temperatur. These particles, often ranging frem 10 t o 100 nanometer in diameter, can by coated with biocompatible polimers, silica, or gold shells to impere stability, prevent aggregation, and enable functionalization with biolecles.
