Dekel Rosenfeld

Congratulations to Zuckerman Faculty Scholar Dekel Rosenfeld, Assistant Professor at Tel Aviv University, on  publishing her latest research in  Advanced Electronic Materials. Together with her team of researchers, Dr. Rosenfeld developed a platform to study cell viability under magnetothermal stimulation in 2D cultures and within 3D magnetic collagen gels.

Abstract:
Magnetic nanoparticles (MNPs) hold great promise for bioelectronic medicine, particularly as transducers of remote activation to control cell function. MNPs in the 20–30 nm size range efficiently dissipate heat under alternating magnetic fields (AMFs), enabling control of heat-sensitive receptors that regulate electrogenic cell signaling. However, effective magnetothermal stimulation tools must maintain cell viability and optimally deliver heat to the cellular microenvironment.
