Abstract: The paper presents a general analytical method for evaluating the magnetic properties of colloidal fluid with magnetic nanoparticles and agar through in vitro Specific Absorption Rate (SAR) measurements. The approach for the determination of magnetic complex susceptibility herein presented reveals itself as simple, rapid, broadband and accurate enough to compete with alternative conventional direct methods requiring complex and expensive instrumentation. In particular, it makes use of indirect equations based on the single order Debye model (Linear Response Theory, LRT) combined with a punctual set of in vitro SAR measurements. The procedure is effective inside the range of validity of the LRT theory and it can be easily applied in the up-growing field of magnetic hyperthermia studies.
