The embodiments herein provide a system and method for detecting, actively targeting and selectively treating the biological targets in a human body by a non-invasive procedure. The system comprises an electromagnetic inductor supported at a predetermined height and rotated to generate a high frequency magnetic field. A head rest is provided at one end of a non-metallic bed provided at the center of the inductor for supporting a patient. A track is arranged below the bed to move the bed and the patient to a desired position indicated by a laser beam to efficiently aim at the targets. The electromagnetic inductor produces electric, magnetic and thermal effects on the nano-conductors attached to the biological targets to activate a nano drug infused into the blood stream of a patient and attached to the surface of the targets to dysfunction or destroy the targets.
