Single vs. two-photon microscopy for label free intrinsic tissue studies in the UV light region
Abstract
Fibrillar distribution in the rat tail tendon and mice liver can be measured using optical methods. Two-photon excitation provides easy assessment of fibrotic collagen types I and II. Single photon deep ultraviolet (DUV) excitation imaging highlights all collagen types without discrimination. Their combination on the same tissue area provides a better overview of collagens in fibrillar diseases.
