Engineering ultraparamagnetic cells

Congratulations to Pradeep, Sonjong, Hunter, Audrey, Vivek, Max, Jenny and Vasant on their new work showing that strong cellular paramagnetism is sufficient for magnetic manipulation and MRI contrast. Their genetic circuit makes bacteria “ultraparamagnetic” by oxidizing and chelating iron in a ferrogel.
