Validation of Oxygen Nanosensor in Mitochondrial Myopathy

"The purpose of the study is to test a device called a nanosensor, which measures oxygen levels (a proxy of mitochondrial function) in muscle. The nanosensor has not been tested in humans nor has it been approved by the FDA.~The study nanosensor measures 1.8 mm width x 6 mm length x 0.3 mm depth. Placement of the sterilized nanosensor involves a small incision for manual placement of the nanosensor in muscle forearm tissue."
