Dear Colleagues:

This special issue focuses on the latest advances in bioprinting technology and scope includes novel bioinks with various organic and inorganic compositions including new developments in photosensitive, responsive bioinks. 
Tissue models are of great interest for drug testing and early stage clinical evaluations, we will consider single as well as composite tissue (more than 1 cell type) based in vitro tissue models developed for drug testing and early stage clinical studies. 
While materials are important, bioprinter play a very important role, we encourage contribution on nee methods of bioprinting technologies both experimental and computational focused at lab and scale up production.
