pH reversibility through cadaveric tissue. XELCI ratiometric images (I700/I620 nm) of the pH sensor clip with two wells fixed on a tibial plate through human cadaveric tissue. Right well contained only the reference scintillator film and the left well had the pH sensing gel film on top of the scintillator layer. The pH of the left well was cycled between 4 and 7 by rinsing with pH 4 and pH 7 buffers alternatively followed by imaging with XELCI through tissue. (a) and (c), set to pH 4. (b) and (d), set to pH 7.
