Abstract
An implantable magnetic relaxation sensor is provided that comprises superparamagnetic nanoparticies functionalized with one or more agents that bond with a biomarker of interest. The sensor is configured for minimally-invasive implantation into a human or animal, and is configured to indicate the implanted sensor's cumulative exposure to the biomarker of interest by analysis using magnetic resonance relaxometry.
