(a) MCF7 cells’ viability results using MTT assay with and without 0.35 mg/mL concentration magnetic fluid for 24 h interaction and magnetic induction heating for 30 min and 60 min. All the groups showed significant cell death compared to untreated cells (no MF and HT) (p < 0.01) except HT 30 min group. Microscopic image of MCF7 cells (b1) control, (b2) after 60 min hyperthermia, (b3) negligible live cells with magnetic fluid interaction after 24 h and (b4) negligible live cells with 24 h MF interaction and hyperthermia treatment of 60 min.
