Abstract
Deep ultraviolet light excites many common fluorophores and is heavily absorbed by biological samples, making it ideal for facial histology of fresh biological samples. Microscopy with ultraviolet surface excitation (MUSE) provides high-resolution diagnostic images comparable to slide-based imaging. However, current implementations of MUSE are limited to the facial surface of the sample, restricting the availability of three-dimensional tissue structure. Our work extends MUSE imaging by providing inexpensive three dimensional images at resolutions comparable to confocal microscopy with the throughput of wide-field imaging. This approach allows comprehensive imaging of macro-scale samples by eliminating constraints on sample size and imaging depth. In this paper, we discuss recent advances in milling with ultraviolet excitation, with a focus on complex neurological structures such as cellular and microvascular networks.
