There is a high prevalence of musculoskeletal injuries in the United States with over 2 million fracture fixation surgeries reported annually. During fracture revision surgeries, medical hardware including pins, wires, screws, plates, and rods can be implanted to maintain bone in proper alignment as the fracture callus forms. There is a clinical need for assessing […]

In order to measure infection-induced chemical changes at the surface of implanted orthopedic plates, we develop and characterize a pH sensor based on the use of X-ray Excited Luminescence Chemical Imaging (XELCI) to non-invasively detect and image changes in pH at the implant surface with high spatial and pH resolution while minimizing tissue scattering effects.

Multifunctional Magnetic Nanoparticles Multifunctional fluorescent and magnetic nanomaterials have broad application utility for bioimaging, magnetic resonance imaging (MRI), magnetic hyperthermia, and drug delivery. An external magnetic field can be used to heat, guide, orient, and image magnetic particles. Particle fluorescence is useful for sensitive target labeling and subsequent imaging. However, fluorescence measurements are difficult to
