Journal ArticleDOI
Bioink properties before, during and after 3D bioprinting
Katja Hölzl,Shengmao Lin,Shengmao Lin,Liesbeth Tytgat,Liesbeth Tytgat,Sandra Van Vlierberghe,Sandra Van Vlierberghe,Linxia Gu,Aleksandr Ovsianikov +8 more
TL;DR: Numerical approaches were reviewed and implemented for depicting the cellular mechanics within the hydrogel as well as for prediction of mechanical properties to achieve the desired hydrogels construct considering cell density, distribution and material-cell interaction.
Journal ArticleDOI
A definition of bioinks and their distinction from biomaterial inks.
Jürgen Groll,Jason A. Burdick,Dong-Woo Cho,Brian Derby,Michael Gelinsky,Sarah C. Heilshorn,Tomasz Jungst,Jos Malda,Vladimir Mironov,Koichi Nakayama,Aleksandr Ovsianikov,Wei Sun,Wei Sun,Shoji Takeuchi,James J. Yoo,Tim B. F. Woodfield +15 more
TL;DR: A simple but general definition of bioinks is proposed, and its distinction from biomaterial inks is clarified, to briefly summarize the historic evolution of this term within the field of biofabrication.
Journal ArticleDOI
Ultra-low shrinkage hybrid photosensitive material for two-photon polymerization microfabrication.
Aleksandr Ovsianikov,Jacques Viertl,Boris N. Chichkov,Mohamed Oubaha,Brian D. MacCraith,Ioanna Sakellari,Ioanna Sakellari,Anastasia Giakoumaki,Anastasia Giakoumaki,David Gray,Maria Vamvakaki,Maria Vamvakaki,Maria Farsari,Costas Fotakis,Costas Fotakis +14 more
TL;DR: No additional effort is required to precompensate for shrinkage or to improve the structural stability of the fabricated photonic crystals; this, combined with the possibility of tuning this material's optical, mechanical, and chemical properties, makes it suitable for a variety of applications by two-photon polymerization manufacturing.
Journal ArticleDOI
Fabrication of woodpile structures by two-photon polymerization and investigation of their optical properties.
TL;DR: Woodpile photonic crystal structures fabricated in organic-inorganic hybrid polymers (Ormocers) and investigation of their optical properties are reported.
Journal ArticleDOI
Laser fabrication of three-dimensional CAD scaffolds from photosensitive gelatin for applications in tissue engineering
Aleksandr Ovsianikov,Andrea Deiwick,Sandra Van Vlierberghe,Peter Dubruel,Lena Möller,Gerald Dräger,Boris N. Chichkov +6 more
TL;DR: The results clearly indicate that 2PP is capable of manufacturing precisely constructed 3D tissue engineering scaffolds using photosensitive polymers as starting material and the applied materials are suitable to support porcine mesenchymal stem cell adhesion and subsequent proliferation.
