Gold Nanoparticles for X-ray Microtomography of Neurons [PDF]
ACS Chemical Neuroscience, 2019 Commonly used methods to visualize the biological structure of brain tissues at subcellular resolution are confocal microscopy and two-photon microscopy. Both require slicing the sample into sections of a few tens of micrometers. The recent developments in X-ray microtomography enable three-dimensional imaging at sub-micrometer and isotropic resolution
