Porous collagen-apatite nanocomposite foams as bone regeneration scaffolds.

abstract：:We describe a near-infrared fluorescent heptamethine dye (IR-780 iodide) with unique properties for sentinel lymph node (SLN) mapping in both small and large animals. This dye has a significant photobrightening effect in serum and a long retention time in the lymphatic system which allows to acquire much higher signal...
