One of the challenges in tissue engineering is the need for cell-size cages where cells can be encapsulated. A porous 3D structure of arbitrary geometry formed from biocompatible material is the perfect option for scaffold manufacturing.
Scaffold-like structure can be produced within a resolution of up to 150 nm capable of entrapping submicrometer sized cells by multiphoton polymerization (MPP) technique. MPP is a flexible technology that allows for the formation of various resolutions and different shaped structures.
