In vivo nerve-specificity of rhodamines and Si-rhodamines [PDF]
Molecular-Guided Surgery: Molecules, Devices, and Applications VI, 2020 Accidental nerve damage or transection of vital nerve structures remains an unfortunate reality that is often associated with surgery. Despite the existence of nerve-sparing techniques, the success of such procedures is not only complicated by anatomical variance across patients but is also highly dependent on a surgeon's first-hand experience that is ...
