Material bioprinted incorporating oxygen sensitive nanoparticles

The bioink could be used to 3D bioprint complex biofilm and tissue-like structures, which can be monitored non-invasively for growth and oxygen distribution, without destructive sampling. A collaborative team of Danish and German researchers have bioprinted a gel material incorporating oxygen sensitive nanoparticles, which can be used for 3D printing of complex biofilm and tissue-like structures. The study, published in Advanced Functional Materials, describes the development of a functionalized bioink, via the implementation of luminescent oxygen sensitive nanoparticles into the print matrix. When blue light excites the nanoparticles, they emit red luminescent light in proportion to the local oxygen concentration....
