Many drugs under development are delivered by nanoparticles in the bloodstream. To monitor changes in the nanoparticles, investigators can retrieve them from the blood by using a device with electrodes that apply oscillating electric fields. The nanoparticles, which are electrically conducting, are strongly attracted to the nearest electrode, while blood cells, which are poor conductors, experience only a weak force toward the nearest electrode,and suspended ions in the blood experience no net force. Explain why the conducting nanoparticles are strongly attracted to the electrodes while other components of the blood are not.
