Different mechanisms are triggered when tissue is exposed to a biomaterial. The success of the biomaterial targeted process, like the release of chemicals, promoted angiogenesis, tissue regeneration, etc. depends on its integration in the tissue . Studying this interaction in vivo requires the ability to image simultaneously deep immersed proteins and biomaterials with high resolution and low damage. Several methods offer solutions but only multiphoton microscopy (MM) has the ability to image with high resolution deep inside the sample. Why is not MM more extensively applied as a platform for investigating biomaterial integration in vivo? The high cost of the typical source for multiphoton microscopy is a clear limitation. Furthermore, imaging several channels simultaneously becomes out of reach for most of the labs.
