Two-Photon Polymerization of an In-Vivo Multiphoton Imaging Window

Intravital microscopy windows for in vivo observation of tissue are desirable in many biomedical fields, from immunology to the assessment of the foreign body reaction to biomaterials. Moreover, they allow one to reduce the number of animals required to statistically validate biomaterials if compared with traditional histopathological analyses of animal biopsies [1], [2].
