Rapid Separation of Bacteria from Blood Using Surface-Modified Magnetic Nanoparticles
Sepsis—a bacterial infection of the blood that can cause a deadly drop in blood pressure—is one of the leading causes of death in the United States. Current diagnostic methods can require up to 72 hours to identify the specific bacteria causing the full-body response. Every hour a patient doesn't receive treatment, their mortality rate increases by 7%. Therefore, our goal is to decrease the amount of time it takes for a doctor to isolate and identify bacteria in blood down to 2 hours. We are developing a filtration procedure that will isolate bacteria from blood using surface-modified magnetic nanoparticles, which can potentially be used to save lives.
