17 quadrillions iron oxide nanoparticles in just one milliliter of magnetic liquid

NanoTherm® is a ferrofluid – a liquid that reacts to the presence of a magnetic field. The liquid acquires its magnetic characteristics from the iron oxide nanoparticles it contains. Despite an average diameter of just 15 nanometers (one nanometer is one millionth of a millimeter), the nanoparticles possess strong magnetic characteristics (known in this context as superparamagnetism).

Thanks to their special aminosilane coating, these tiny magnets can be finely dispersed in water, forming a colloidal solution that can be introduced via a syringe. In addition, they have been specifically designed to produce heat inside the alternating magnetic field applicator, the NanoActivator®. The nanoparticles act as transducers and are exceptionally efficient at converting energy into heat. Their coating ensures that they form a stable depot within the tumor tissue. These characteristics are unique to NanoTherm® and form the basis of NanoTherm® therapy.
