Bone fracture healing includes complex and sequence of dynamic events to restore the integrity and biomechanical properties of the bone. While most of the fractures heal without any problem, healing is sometimes compromised. Two significant fracture healing complications are orthopedic implant-associated infections and non-unions/delayed union. These can be interrelated causes as well. Implant-associated infection can cause implant loosening, and as a result, it can delay the fracture healing process. Herein, we describe two different types of sensors that can be used in monitoring biochemical and biomechanical processes of fracture healing using X-rays.

In this dissertation we describe methods for measuring infection relevant biochemical analytes using radioluminescent and ultrasound luminescent materials. Films and nanoparticles fabricated with europium doped gadolinium oxysulfide (Gd2O2S:Eu3+) are used to quantitatively measure radiolabeled pharmaceutical concentration, specifically tritium labeled vancomycin (3H-vancomycin). Europium and dysprosium doped strontium aluminate is used to fabricate an ultrasound modulated, pH sensing film. These methods are indicated for theranostic evaluation of implant associated infection. Bacterial biofilms are inherently resistant to traditional antibiotic treatment and can coat biomedical implants. These biofilm related infections are difficult or impossible to eradicate …
