Mild and selective oxidation of cellulose fibers in the presence of N-hydroxyphthalimide.

abstract：:Bioprinting has become an important tool for fabricating regenerative implants and in vitro cell culture platforms. However, until today, extrusion-based bioprinting processes are limited to resolutions of hundreds of micrometers, which hamper the reproduction of intrinsic functions and morphologies of living tissues....
