Tissue Scaffolds (IMAGE) Optica Caption In this image, a multi-layer tissue scaffold created with single-focus two-photon polymerization ("2PP") (a) is shown beside one created with multifoci two-photon polymerization (b). The two scaffolds are structurally similar, but the one created with multifoci 2PP was completed in approximately one-fourth the time. In image c, cells from the inner lining of bovine blood vessels are shown growing on the multifoci-created scaffold.
