Using the body’s naturally occurring ions to help transmit data from implantable devices
MediSCAPE imaging of fresh human kidney compared to gold standard periodic acid-Schiff (PAS) histology of the same tissue. Center shows large area scanned using MediSCAPE. Panels point to specific features of the kidney that are either normal or represent disease. 488 nm excited autofluorescence is color-coded in a yellow-blue scale.
