The Company

MediSieve is an exciting medical device therapeutics start-up developing “magnetic blood filtration”, a revolutionary treatment for blood-borne diseases which removes pathogens directly from the bloodstream. Our technology is like dialysis, circulating a patient’s blood through an external loop to remove disease causing targets. While dialysis relies on non-specific size based filtration, MediSieve uses magnetic beads coated with antibodies to target specific components, and magnetic forces to extract them. Our initial target diseases are malaria, sepsis and leukaemia. More details on
