An interdisciplinary group of scientists in Lithuania has tested a complex tissue scaffold made by direct laser writing in vivo for the first time. The scaffold has exhibited high performance and biocompatibility, paving the way for a clinical trial of the desirable tissue-engineering technique.
Direct laser writing (DLW) is an advanced way of structuring materials with light, without the use of a mask. Instead, a tightly focused laser beam scans a photosensitive material, creating a structure directly from a computer model. In this way it is like a 3D printer – but one with unmatched spatial resolution and material choice.
