Using Bacteria to Kill Cancer Cells

Bacteria could be armed with destructive payloads that will kill cancer cells directly and evoke, or evoke, anti-tumor immune responses at the same time. Simone Schurler has an ingenious solution using bacteria that naturally accumulate iron particles that make them magnetic. She creates rotating magnetic fields that behave like whirlpools to trap the magnetic bugs where she wants them in the vicinity of cancers.
