Description
The most widespread 3D bioprinting technologies are based on computer-controlled deposition of cells or assembly of cellular units, and thus cannot achieve spatial resolution better than few tens of micrometers. Lithography-based methods approach the problem from a different direction, by producing 3D structures within cell-containing materials and can therefore overcome this limitation. Among these methods, high-resolution 3D printing employing nonlinear absorption of femtosecond laser radiation, also referred to as multi-photon lithography, is an outstanding one as it can produce features even smaller than a single mammalian cell.
Numerous publications already demonstrated that MPL can be used to produce stimuli-responsive structures from different materials, including hydrogels. In this talk, the recent progress of MPL for 4D printing applications, as well as its advantages and limitations, along with the perspectives for 4D bioprinting will be discussed. The presentation is supported by numerous examples.
