Bell Biosystems is a biotechnology company developing and commericializing advances in sythetic biology to provide tools for researchers. Its flagship technology, The Magnelle, is a synthetic organelle that produces magnetic nanoparticles from intracellular iron. This, in turn, creates a magnetic phenotype in the cell allowing a researcher to easily track the cell and its progeny. Besides allowing real-time tracking, the magnetic nature of the organelles allows the control and/or localization of the implanted cells and also allows the destruction of implanted cells via magnetic-induced hyperthermia. The technology pioneered by Bell Biosystems provdides researchers with a tool to both increase efficiency as well reduce the cost of their research.
